This section describes how to determine available disk space, how to increase available disk space by compressing files and purging files, and how to add a hard disk to a NetWare server.
You should monitor available disk space regularly and keep a log so you can track disk usage over time. This information helps you make the best use of your disk space management options, such as adding a new hard disk, compressing files, and migrating data to an offline system such as an optical disc library.
At the workstation, type
NDIR volume: /VOL <Enter>
Statistics for the volume you selected appear on the screen.
For more information about the NDIR utility, see NDIR in Utilities Reference.
Write down the percentage shown for Space remaining on volume.
Repeat this procedure weekly for each volume.
Tracking this percentage over time helps you predict when a volume may run out of disk space.
HINT: You may want to enter the disk space information into a spreadsheet to create a graph of disk usage over time.
File compression allows you to store more information on a server hard disk.
File compression is enabled or disabled at the volume level. Once enabled, it can be turned on and off for individual files and directories by setting compression attributes with FLAG, FILER, or the NetWare Administrator graphical utility.
See Setting Compression for a File or Directory
When you install NetWare 4.11, the default is to enable file compression. However, you can override the default and disable file compression during installation.
If you disable file compression, you can enable it later. Once enabled, however, file compression cannot be turned off unless you first re-create the volume.
It isn't necessary to separate applications from data for file compression, because the Days Untouched Before Compression SET parameter can eliminate the compression of applications that are used regularly.
This parameter specifies the number of days that must pass without access to a file before the file can be compressed. The parameter uses the last accessed date to gauge whether a file should be compressed or not.
To avoid the overhead of uncompressing files that don't compress well, the system calculates the compressed size of a file before actually compressing it.
If no disk space will be saved by compression, or if the size difference does not meet the value specified by the Minimum Percentage Compression Gain SET parameter, the file is not compressed.
For a file to be uncompressed, there must be enough free space on the volume to accommodate the uncompressed file size.
When you install NetWare or create a new volume, file compression is enabled by default. You may override the default and disable file compression when the volume is created.
The following procedure explains how to enable file compression on a volume for which compression was disabled.
NOTE: Once file compression is enabled for a volume, you can't disable it unless you first re-create the volume.
WARNING: If you have a CD-ROM volume mounted as a NetWare volume, you should treat it as a read-only volume.
Do not use file compression on a CD-ROM volume. This will corrupt the CD-ROM volume index data. If you do so by mistake, use the CD command to rebuild the volume's index file. For command syntax, see CD in Utilities Reference.
At the server console prompt, type LOAD INSTALL <Enter>
Select Volume Options from the Installation Options menu. A list of volumes appears. Select the volume for which you want to enable file compression. The Volume Information screen appears, showing the current settings for the volume. Use the Down-arrow key to move the cursor to the File Compression field and press <Enter>. Change the setting from Off to On. Press <Esc> twice to save the new value and redisplay the Installation Options menu. Once file compression is enabled for a volume, turn it on or off for individual files and directories by using FLAG, FILER, or NetWare Administrator. You may want to group the files you want to compress into different directories from those you don't want to compress. For example, if you have data you don't access often, such as quarterly reports, you can create a directory called QUARTER and set it for immediate compression. Then when files are moved into the QUARTER directory, they stay compressed until the next report time, taking up much less disk space. You can use the FLAG utility from a workstation to set attributes for a directory or file. The attributes are Immediate Compress (IC) and Don't Compress (DC).
At the workstation, type FLAG <Enter>
The attributes for the current drive appear. If you are not in the directory where you want to set the file compression attributes, enter the drive letter or the complete path after the FLAG command. Enter the file compression option you want to apply to the file or directory. For example, if you want the files in the subdirectory LETTERS to be compressed each time a file is created or moved into the directory, type the Immediate Compress option: FLAG SYS:DOC\LETTERS IC <Enter>
If you have an APPS directory for files that you do not want compressed at any time, type the Don't Compress option: FLAG SYS:APPS DC <Enter> For more information, see FLAG in Utilities Reference. You can set file compression attributes with the FILER menu utility. The attributes are Immediate Compress (IC) and Don't Compress (DC). Online help appears at the bottom of each screen to help you use FILER, and you can press <F1> for more detailed help.
At the workstation, type FILER <Enter>
A list of available options appears. Select Manage Files and Directories from the Available Options menu and press <Enter>. A list of files appears in the Directory Contents window. Select the file you want to set file compression attributes for, and press <F10>. Select View/Set File Information from the File Options menu and press <Enter>. Select the Attributes list in the File Information display and press <Enter>. The Current File Attributes window appears. Press <Insert> to see other file attributes. Select Immediate Compress or Don't Compress from the Other File Attributes window and press <Esc>. The compression attribute you selected (Ic or Dc) appears in the attributes list. To exit FILER, press <Alt>+<F10>. You can set file compression attributes with the NetWare Administrator. The attributes are Immediate Compress (IC) and Don't Compress (DC).
Start NetWare Administrator. Select the file you want to set file compression attributes for. To see a file in the NetWare Administrator, choose a volume object and then choose the directory the file resides in. From the Object menu, choose Details. Choose the Attributes button. From the File Attributes list, choose Immediate Compress or Don't Compress. Choose OK.

You can suspend file compression temporarily by using the Enable File Compression SET parameter. Follow this procedure.
At the server console prompt, load either SERVMAN or MONITOR.
LOAD SERVMAN | MONITOR <Enter>
NOTE: You can also set parameters with the SET command. See SET in Utilities Reference.
Select File System from the Categories menu. Select Enable File Compression and change the value to OFF. If this parameter is set to OFF, any files that would normally be compressed are queued and will be compressed as soon as the parameter is reset to ON. If you have many files to compress, server performance may be affected when you turn file compression back on. If so, make sure you set file compression to be activated during nonpeak hours. See the Compression Daily Check Stop Hour and the Compression Daily Check Starting Hour parameters in Table 30. Press <Esc> twice to display the Update Options menu. Choose Update AUTOEXEC.NCF and STARTUP.NCF Now from the Update Options menu. You are prompted to update the STARTUP.NCF file. If the SET parameters are in the STARTUP.NCF file, press <Enter> to update the values in the file. Otherwise, press <Esc>. You are prompted to update the AUTOEXEC.NCF file. If the SET parameters are in the AUTOEXEC.NCF file, press <Enter> to update the values. Otherwise, press <Esc>. Changes to the parameters take effect immediately. If you do not update either of the .NCF files, changes to the parameters last only until you reboot the server.
You can control various aspects of file compression by using the file compression SET parameters. For example, the Compression Daily Check Starting Hour parameter determines when the file compressor begins scanning volumes for files that need to be compressed. File compression SET parameters do not affect volumes on which compression is disabled.
To change SET parameters, execute the SET command at the server console prompt, or use the SERVMAN or MONITOR utility.
For more information about executing the SET command, see SET in Utilities Reference.
For more information about using SERVMAN, see SERVMAN in Utilities Reference. The instructions for using SERVMAN also apply to MONITOR.
NOTE: In most cases, the default values for the SET parameters are the most efficient. We recommend you read this section before changing the default values.
You might want to add the file compression SET parameters to your AUTOEXEC.NCF or STARTUP.NCF file so that they are executed whenever the server is brought up.
You can use EDIT or INSTALL to edit the AUTOEXEC.NCF or STARTUP.NCF file. You can use SERVMAN or MONITOR to change the value of parameters that have already been set in either file.
Table 30 lists the file compression SET parameters and their default values. The settings apply to all files and directories in compression-enabled volumes on the server.
Table 30. SET Parameters for File Compression
| SET Parameter and Default | Explanation |
|---|---|
Compression Daily Check Stop Hour=6 (6:00 a.m.) |
Sets the hour when the file compressor stops scanning volumes for files that need to be compressed. Hours are specified by a 24-hour clock. Supported values: 0 to 23. |
Compression Daily Check Starting Hour=0 (midnight) |
Sets the hour when the file compressor starts scanning volumes for files that need to be compressed. Hours are specified by a 24-hour clock. Supported values: 0 to 23. |
Minimum Compression Percentage Gain=20 (%) |
Specifies the minimum percentage a file must compress in order to remain compressed. |
Enable File Compression=ON |
Allows file compression to occur on compression-enabled volumes. If you set this parameter to OFF, compression is suspended temporarily. Files flagged for compression are queued until the parameter is reset to ON. |
Maximum Concurrent Compressions=2 |
Specifies the number of volumes that can compress files at the same time. Increasing this setting may slow server performance. |
Convert Compressed To Uncompressed Option=1 |
Determines how the server stores a file after the file has been accessed.
|
Decompress Percent Disk Space Free To Allow Commit=10(%) |
Specifies the percentage of free disk space required on a volume before committing an uncompressed file to disk. This prevents newly uncompressed files from filling up the volume. |
Decompress Free Space Warning Interval=31 minutes 18.5 seconds |
Specifies the interval for displaying warning alerts when the volume has insufficient free disk space for uncompressed files. To turn off the alerts, set the parameter to 0. |
Deleted Files Compression Option=1 |
Determines how the server handles unpurged deleted files.
|
Days Untouched Before Compression=14 |
Specifies the number of days that must pass with no access to the file before the file can be compressed. |
Purging deleted files frees disk space on the NetWare server's hard disk. You can purge files manually, or you can set up automatic purging.
WARNING: Purged files cannot be salvaged.
To purge deleted files manually, use the NetWare Administrator graphical utility, or the FILER or PURGE text utility. See Purging Files You can set up automatic purging of all files on a NetWare server's hard disk, by setting the relevant parameters. At the server console prompt, load either SERVMAN or MONITOR. LOAD SERVMAN | MONITOR <Enter>
NOTE: You can also set parameters with the SET command. See SET in Utilities Reference.
Choose Server Parameters from the Available Options menu. Choose File System from the Categories menu. Change the following parameters in the File System menu to the indicated values: WARNING: These settings cause the system to purge deleted files immediately. Therefore, the files cannot be salvaged. Be sure you have backups of important files. Immediate Purge Of Deleted Files=ON File Delete Wait Time=0 Minimum File Delete Wait Time=0
Press <Esc> twice to reach the Update Options menu. Choose Update AUTOEXEC.NCF and STARTUP.NCF Now from the Update Options menu. The system displays the path to the AUTOEXEC.NCF file. If desired, press <Enter> to update the file. The new parameter values take effect immediately. You do not need to reboot the server.

The High Capacity Storage System (HCSS) extends the storage capacity of a NetWare server by integrating one or more optical library units, or jukeboxes, into the NetWare file system.
HCSS moves files between the server's hard disk and optical disks in a jukebox. HCSS uses hard disk free space to cache the files stored on optical disk. When the hard disk free space reaches a configurable threshold, HCSS migrates files to optical disk.
If you have installed an HCSS system on your network, you can set it to use as much or as little of the server's hard disk space as you want.
HCSS procedures are described in Migrating Data Using the High Capacity Storage System

The procedures in this section explain how to add the following:
Select the procedure that fits your situation.
To add an additional internal IDE hard disk, complete the following steps.
Bring down the server by typing DOWN <Enter> EXIT <Enter>
Turn off power to the server. Install and cable the hard disk. Make sure that the jumpers are configured so that one disk is the master and one the slave. Refer to the documentation that came with the hard disk for more information. Configure the computer to recognize the new disk. For example, you may need to run the CMOS or EISA configuration utility. Refer to the documentation that came with the computer for information about configuration methods and requirements. Reboot the server. At the server console prompt, type LOAD INSTALL <Enter>
Use INSTALL to create a NetWare partition. If you need help, see Creating NetWare Disk Partitions Create a new volume or designate the partition as a new segment of an existing volume. If you need help, see Creating Volumes or Adding a Segment to an Existing Volume To install an internal SCSI hard disk and new adapter, complete the following steps.
Bring down the server by typing DOWN <Enter> EXIT <Enter>
Turn off power to the server. Configure and install the new adapter.
Install the hard disk, connect the power cable to the disk, and cable the disk to the new adapter. If necessary, configure the computer to recognize the new disk and adapter. Refer to the documentation that came with the computer for more information about configuration methods and requirements. Reboot the server. At the server console prompt, type LOAD INSTALL <Enter>
Use INSTALL to load the disk driver. For more information about loading drivers, see Loading Disk Drivers Use INSTALL to create a NetWare partition. If you need help, see Creating NetWare Disk Partitions Do one of the following steps: A subsystem contains additional hard disks. To add a SCSI hard disk to an existing adapter in a subsystem, complete the following steps.
Bring down the server by typing DOWN <Enter> EXIT <Enter>
Turn off power to the subsystem. Install the hard disk and cable it to the adapter. Set the SCSI ID for the drive and terminate the SCSI bus. Refer to the documentation that came with the hard disk for more information about SCSI IDs and termination requirements. Turn on the power to the disk subsystem. Reboot the server. At the server console prompt, type LOAD INSTALL <Enter>
Use INSTALL to create a NetWare partition. If you need help, see Creating NetWare Disk Partitions Do one of the following steps: If a hard disk becomes unreliable or unusable, follow this procedure to remove the disk from the network. Once you start this procedure, you must complete it; otherwise, the system hangs as it looks for the missing hard disk. If you have been backing up your data consistently and verifying its integrity, you will be able to reload data for the volumes affected by the disk failure. WARNING: Although some hard disks (called hot plug devices) can be removed while the system is running, we do not recommend this practice. If you do try to replace a mirrored hot-plug disk while the system is running, you must unmirror the disk first or run SCAN FOR NEW DEVICES as soon as the disk is removed. Failure to do one of these steps could cause the loss of all data on the disk's mirrored partner when you install the replacement disk. See Unmirroring Hard Disks and SCAN FOR NEW DEVICES in Utilities Reference.
Make a backup copy of the data on the hard disk and verify its validity. Make sure the backup copy contains uncorrupted versions of all files and directories on the hard disk. If the disk is mirrored, dismount the volumes that reside on the disk by using either the DISMOUNT command or the INSTALL NLM. DISMOUNT [volume_name] <Enter>
Unmirror the hard disk if it is mirrored. At the server console, bring down the server by typing DOWN <Enter> EXIT <Enter>
Turn off the system containing the hard disk to be replaced. Remove the hard disk and install the replacement. Use the instructions that came with the hard disk and see Loading Disk Drivers Turn on power and reboot the server. If the replacement disk has been used before, delete any existing partitions on the replacement disk. WARNING: Deleting disk partitions destroys all data on the deleted partitions. Be sure you delete the partitions on the new disk, not an existing disk.
Create a partition on the replacement disk. See Creating NetWare Disk Partitions Complete one of the following steps: If the disk was not mirrored, create the volumes that previously resided on the hard disk and restore the data from a backup. See Creating Volumes If the hard disk was mirrored, remirror the disk. See Mirroring and Duplexing a Hard Disk IMPORTANT: If you replaced the Not Mirrored disk rather than the Out of Sync disk, recover the volume data from the Out of Sync disk before remirroring the disks. After you add or replace a hard disk on your NetWare server, you must load the corresponding disk driver. Loading a disk driver enables communication between the disk controller and the server's CPU. Load the disk driver once for each disk adapter you want to support. Most NetWare 4 disk drivers have a help file that appears on the screen as you highlight the driver. Refer to these descriptions to determine which driver to load. At the server console prompt, load INSTALL by typing LOAD INSTALL <Enter>
Select Driver Options from the Installation Options menu. Choose Configure Disk and Storage Device Drivers from the Driver Options menu. If you want INSTALL to search the installed drivers and find those compatible with your disk adapter and disk, choose Discover and Load Additional Drivers; otherwise, continue with Step 5. If INSTALL finds only one driver compatible with your disk adapter, it loads the driver automatically. If INSTALL finds more than one driver compatible with your disk adapter, it displays a message listing the hardware it detected. Press <F3> to see a list of drivers compatible with the detected hardware. Select a driver from the list. After the driver is loaded, choose Return to Previous Menu. If you loaded a .HAM module, NetWare searches for the .CDM module compatible with the .HAM module. If NetWare finds the .CDM module, it loads the module automatically. If NetWare does not find the .CDM module, it displays a list of available .CDM modules. If the screen displays a list of .CDM modules, select the one you want. If you want to load additional drivers, continue with Step 5; otherwise, press <Alt>+<F10> to exit INSTALL. NOTE: In machines with PCI buses and sometimes in machines with EISA hardware, INSTALL may not detect all the drivers associated with the disk adapters. When this happens, INSTALL displays a message that lists the hardware for which disk drivers were not detected. The message prompts you to press <F3> to see a list of all available drivers. Select the appropriate driver from the list and continue with Step 7 to modify driver parameters.
Choose Load an Additional Driver from the Additional Drivers Actions menu. Select the disk driver you want to load and press <Enter>. For example, if you are using an AT controller, the disk driver filename is ISADISK.DSK and its description filename is ISADISK.DDI. IMPORTANT: Some drivers do not have a description file (a configuration file that's appended to the driver). These drivers have to be loaded manually, at the system console. To load these drivers, follow the screen prompts or press <F1> for help.
Choose Select/Modify Driver Parameters. The cursor becomes active in the parameter window for the selected driver. Default parameters may be displayed in the fields. Use the arrow keys to move from field to field. Press <Enter> to change a value in a field. When you move the cursor to a field, the system displays a help window that describes the field. When you press <Enter> to change a value, the system usually displays a pop-up list of values from which you select the desired one. When finished setting parameter values, press <F10>. Select Save Parameters and Load Driver. The system displays a message asking if you want to load another driver. If you want to load an additional driver, select Yes and repeat Steps 5 through 10. You can load the same driver more than once if you have additional disk controller boards of the same type. (Remember to check controller board settings for conflicts.) To exit INSTALL, press <Alt>+<F10>.

NetWare partitions can be created on any hard drive and can coexist with other partitions such as DOS, OS/2, and UNIX.
If you have partitions from previous versions of NetWare that you are no longer using, you can delete them and create a new NetWare partition. (See Deleting NetWare Disk Partitions for more information.)
NOTE: Some machine vendors such as COMPAQ* create a small partition that setup and configuration utilities can be run from. Don't delete this partition.
At the server console prompt, type LOAD INSTALL <Enter>
Select Disk Options from the Installation Options menu. Select Modify Disk Partitions and Hot Fix from the Available Disk Options menu. If you have more than one disk, the Available Disk Drives list appears. If this list appears, select the disk you want to partition. A list of existing partitions appears, along with the Disk Partition Options menu. Select Create NetWare Disk Partition from the Disk Partition Options menu. NetWare allows only one NetWare partition per disk (unless the machine vendor presents multiple hard drives as one logical drive). If the disk has more than one free partition area, select an area for the NetWare partition. A screen containing disk partition and Hot Fix information with their default values appears. The cursor is on the Partition Size field. If you don't want to use the whole partition for NetWare, type a smaller value in the Partition Size field. The difference between the original size and the smaller size is added to the free space on the disk. To change the size of the data area, use the arrow keys to move the cursor to one of the Data Area fields, and then type in a new value. One field contains the size of the data area in blocks, the other in megabytes. When you change the value in one field, the system changes the corresponding value in the other field. To change the size of the Hot Fix Redirection Area, use the arrow keys to move the cursor to one of the Hot Fix Redirection Area fields, and then type in a new value. One field contains the size of the area in blocks, the other as a percentage of the partition. When you change the value in one field, the system changes the corresponding value in the other field. Press <Esc> to display the Create NetWare Partition? window. Select Yes. Press <Esc> twice to redisplay the Available Disk Options menu. To create NetWare partitions on additional disks, repeat Steps 3 through 10 for each disk. When finished, go to Step 12. If you want to mirror a disk, see Mirroring and Duplexing a Hard Disk Otherwise, press <Esc> to exit. NOTE: The partition table displays partitions such as OS/2, UNIX, and XENIX* as Unknown Partition Type #. Don't delete these unknown partition types unless you know what is on them. Some machine vendors such as COMPAQ create a small partition that setup and configuration utilities can be run from. Don't delete this partition.
At the server console prompt, type LOAD INSTALL <Enter>
Select Disk Options from the Installation Options menu. Select Modify Disk Partitions and Hot Fix from the Available Disk Options menu. If you have more than one disk, the Available Disk Drives list appears. If this list appears, select the disk you want from the Available Disk Drivers list. A list of disk partitions on the selected disk appears at the top of the screen. The Disk Partition Options menu appears at the bottom of the screen. Select Delete Any Disk Partition from the menu. A list of the available disk partitions is displayed in a pop-up menu. Select the disk partition you want to delete. If you did not delete existing volumes from the disk partition, a message similar to the following appears: If you are ready to delete the partition, press <Enter>; otherwise, press <Esc>. If you press <Enter>, a confirmation box is displayed containing the message Delete Disk Partition? Select Yes. The space occupied by the deleted disk partition now appears as Free Space in the list of disk partitions at the top of the screen. You can create a new disk partition in this free space. NetWare 4 enables you to protect data from hard disk failure by duplicating, or mirroring, one hard disk's data on one or more other hard disks. When you mirror hard disks over different disk channels or host bus adapters, this is called duplexing. The INSTALL processes for mirroring and duplexing are the same. The term mirroring is used in all menus to refer to both mirroring and duplexing. IMPORTANT: If you want mirroring with IDE/ATA disks, you must duplex them by mirroring them on separate host adapters or on different ports of a multiport IDE/ATA host adapter, with each port or adapter configured to support a single drive. This requirement is necessary because of a design limitation of the IDE drives that prevents them from continuing normally after one of the drives fails.
Following are some considerations to keep in mind when using mirrored disks:
IMPORTANT: When mirroring two disks, one of the disks should be blank. Delete all partitions from the blank disk and then create a new NetWare partition on it. Do not create any volumes. When you mirror the disks, the disk containing data will be mirrored to the blank disk.
To mirror two disks to each other, follow these steps.
At the server console prompt, type LOAD INSTALL <Enter>
Choose Disk Options from the Installation Options menu. Choose Mirror/Unmirror Disk Partitions from the Available Disk Options menu. A Disk Partition Mirroring Status window appears. This window lists each device and its mirrored status. For example: The meaning of each status is as follows:
Mirrored The partition is mirrored to another partition. Not Mirrored The partition is not mirrored to another partition. Out of Sync The partition was mirrored to another partition, but is currently unmirrored. From the Disk Partition Mirroring Status list, choose one of the two devices (disk partitions) you want to mirror to each other. See Device numbering in Concepts for an explanation of how logical partitions relate to the installed hard disks. A Mirrored Disk Partitions list appears. This window displays any hard disks that are currently mirrored to the partition you selected. You must now specify another partition to be mirrored to the selected partition. Press <Insert>. The system displays the Available Disk Partitions list---a list of all partitions that can be mirrored to the first partition. Select the other partition from the Available Disk Partitions list. The system mirrors the two partitions to each other so that the blank partition contains the data from the other partition. NOTE: If you are mirroring hard disks, the status on the Mirrored Disk Partitions list is now Out of Sync for one of the disks. As soon as mirroring is complete, the status of both disks changes to In Sync. You must unmirror mirrored hard disks before you can delete a partition or conduct surface tests on a disk. WARNING: If you plan to replace a hot-plug mirrored disk while the system is running, you must first unmirror the disk. Failure to unmirror the disk could cause the loss of all data on its mirrored partner when you install a replacement disk.
At the server console prompt, type LOAD INSTALL <Enter>
Choose Disk Options from the Installation Options menu. Choose Mirror/Unmirror Disk Partitions from the Available Disk Options menu. The system displays the Disk Partition Mirroring Status list. Select a mirrored partition from the list. After you select a partition, the system displays the list of disk partitions in the mirrored set. Select the hard disk partition you want to unmirror from the first disk and press <Delete>. The system displays a message warning that the partition contains volume information. Press <Enter> to clear the message. Choose Yes to salvage the information on the partition or No if you do not want to salvage the data.
Press <Enter> to clear the message. The system prompts you to enter a new name for the volume. Enter the new volume name. The Mirrored Disk Partitions list is redisplayed. Press <Esc> from the Mirrored Disk Partitions list. The Partition Mirroring Status list is displayed. The Out of Sync status appears next to the disk you unmirrored. You can now
You must first remove any existing volume information from the partition, if necessary. See Recovering Data from an Unmirrored (Out of Sync) Hard Disk for information about removing existing volume information. Then see Creating Volumes for instructions on creating the new volume segment.Procedure
