Novell Doc: OES 1 - NSS Management Utility (NSSMU)

3.2 NSS Management Utility (NSSMU)

The Novell Storage Services Management Utility (NSSMU) is a console-based utility for managing NSS storage media on a server. You can use NSSMU at any time as an alternative to the browser-based iManager Storage plug-in.

3.2.1 NSSMU for Linux

For OES Linux, NSSMU is installed when you install NSS. The Linux install creates symlinks in the /opt/novell/nss/sbin folder for common nss utilities, including NSSMU. Symlinks allow the path to NSSMU to become part of the root user’s path, which allows you to run it with the command nssmu.

The following table identifies key functions available in NSSMU for Linux.

Table 3-14 Summary of Management Options in NSSMU for Linux

Management Options	Description
Device Management F1 = Help F3 = Initialize device (do not initialize your system device) F5 = Refresh display F6 = Share (shareable/not shareable for clustering) Enter = Show partitions	Initialize and maintain physical storage devices and software RAID devices available to this server. See Software RAID Devices to create, repair, or delete RAIDs.
Pool Management Ins = Create a pool Del = Delete a pool F3 = Expand a pool (add partitions) F4 = Update NDS™/eDirectory F5 = Refresh details of the pool F6 = Rename a pool F7 = Activate/deactivate pools F8 = More (list more options) F9 = Show/Hide deleted volumes F10 = List devices (that a pool resides on) Enter = Show volumes (on a server or pool)	Create, delete, rename, and expand NSS storage pools to efficiently use all free space in the available devices.
Volume Management Ins = Create an unencrypted volume Del = Delete a volume F2 = Rename mount point for the volume (new path with volume name) F3 = Rename volume F4 = Update NDS/eDirectory F5 = Refresh details of the volume F6 = View compression statistics F7 = Dismount/mount a volume. If it is encrypted, the volume prompts for a password on the first mount after a system boot or reboot. F8 = More (list more options) F9 = Name Space - choose Long, UNIX, DOS, Mac Enter = Set or view volume properties	Use this menu option to create, delete, rename, activate/deactivate, and mount/dismount NSS volumes and to set their attributes. To store data in encrypted format, specify a password when you create the volume. This enables the Encryption attribute. The encryption setting persists for the life of the volume. The encryption password can be 2 to 16 standard ASCII characters, with a suggested minimum of 6. The password generates a 128-bit NICI key for encryption. You must supply the password on the first volume activate after a system boot or reboot. On Linux, you can mount encrypted volumes only from NSSMU on the first time after a system reboot. Provide the password when needed. Until you provide a password for encrypted volumes, you cannot mount multiple encrypted volumes at a time.
Software RAID Management Ins = Create a software RAID (0, 1, or 10) Del = Delete a software RAID device F3 = Expand a RAID device (add partitions) F4 = Rename a RAID device F5 = Refresh details of the software RAID device F6 = Restripe (resume restriping for paused RAID 0) Enter = Show segments (list member partitions for selected device)	A software RAID device emulates a hardware RAID device. RAID devices combine partitioned space on multiple physical devices into a single virtual device that you manage like any device. Each member device contributes an equal amount of space and only a single partition to the RAID.
Partition Management Ins = Create an NSS partition Del = Delete an NSS partition F5 = Refresh details of the partition F6 = Label Enter =Show volumes	Use this option to view details about partitions. You can also delete a single partition at a time when repairing a failed software RAID partition. To delete all software RAID partitions, delete the RAID itself.

Management Options

Description

Device Management

F1 = Help
F3 = Initialize device (do not initialize your system device)
F5 = Refresh display
F6 = Share (shareable/not shareable for clustering)
Enter = Show partitions

Initialize and maintain physical storage devices and software RAID devices available to this server. See Software RAID Devices to create, repair, or delete RAIDs.

Pool Management

Ins = Create a pool
Del = Delete a pool
F3 = Expand a pool (add partitions)
F4 = Update NDS™/eDirectory
F5 = Refresh details of the pool
F6 = Rename a pool
F7 = Activate/deactivate pools
F8 = More (list more options)
F9 = Show/Hide deleted volumes
F10 = List devices (that a pool resides on)
Enter = Show volumes (on a server or pool)

Create, delete, rename, and expand NSS storage pools to efficiently use all free space in the available devices.

Volume Management

Ins = Create an unencrypted volume
Del = Delete a volume
F2 = Rename mount point for the volume (new path with volume name)
F3 = Rename volume
F4 = Update NDS/eDirectory
F5 = Refresh details of the volume
F6 = View compression statistics
F7 = Dismount/mount a volume. If it is encrypted, the volume prompts for a password on the first mount after a system boot or reboot.
F8 = More (list more options)
F9 = Name Space - choose Long, UNIX, DOS, Mac
Enter = Set or view volume properties

Use this menu option to create, delete, rename, activate/deactivate, and mount/dismount NSS volumes and to set their attributes.

To store data in encrypted format, specify a password when you create the volume. This enables the Encryption attribute. The encryption setting persists for the life of the volume. The encryption password can be 2 to 16 standard ASCII characters, with a suggested minimum of 6. The password generates a 128-bit NICI key for encryption. You must supply the password on the first volume activate after a system boot or reboot.

On Linux, you can mount encrypted volumes only from NSSMU on the first time after a system reboot. Provide the password when needed. Until you provide a password for encrypted volumes, you cannot mount multiple encrypted volumes at a time.

Software RAID Management

Ins = Create a software RAID (0, 1, or 10)
Del = Delete a software RAID device
F3 = Expand a RAID device (add partitions)
F4 = Rename a RAID device
F5 = Refresh details of the software RAID device
F6 = Restripe (resume restriping for paused RAID 0)
Enter = Show segments (list member partitions for selected device)

A software RAID device emulates a hardware RAID device. RAID devices combine partitioned space on multiple physical devices into a single virtual device that you manage like any device. Each member device contributes an equal amount of space and only a single partition to the RAID.

Partition Management

Ins = Create an NSS partition
Del = Delete an NSS partition
F5 = Refresh details of the partition
F6 = Label
Enter =Show volumes

Use this option to view details about partitions. You can also delete a single partition at a time when repairing a failed software RAID partition.

To delete all software RAID partitions, delete the RAID itself.

3.2.2 NSSMU for NetWare

NSSMU is the interface you use to set up your basic NSS storage solution during the NetWare installation. For example, you must use NSSMU to create the sys pool and sys: volume. NSSMU allows limited creation and management of the following NSS components: devices (including software RAIDs 0, 1, 5, 10, and 15), partitions (NSS and iSCSI), pools, and volumes.

To set up iSCSI partitions, use the Partitions option in NSSMU. You must have iSCSI target software loaded to make your server into an iSCSI disk server. You cannot create iSCSI devices during the initial installation. For information, see the iSCSI 1.1.3 Administration Guide for NetWare 6.5 .

IMPORTANT:NSSMU is not meant to replace iManager or any other NetWare file system management utilities. However, it is the only management tool that can access your NetWare server if you accidentally delete or rename the sys: volume.

Load the NSSMU module ( nssmu.nlm) from the command line of the server console by entering

nssmu

The following table identifies key functions available in NSSMU for NetWare.
