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.

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.

Table 3-15 Summary of Management Options in NSSMU for NetWare

Function Keys

  • F3 = Initialize device (not for your sys pool or sys: volume)
  • F4 = Multipath (available only if there are multiple paths for the device)
  • F5 = Select/deselect one or more devices for Initialize or Share actions
  • F6 = Share (shareable/not shareable for clustering)
  • F9 = Refresh details of the device
  • Enter = Show partitions

Use this menu option to initialize and maintain a wide selection of 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)

Volume Management

  • Ins = Create an encrypted or unencrypted NSS volume
  • Del = Delete a volume
  • F3 = Rename a volume
  • F5 = Refresh details of the volume
  • F6 = Deactivate/activate the volume. If it is encrypted, the volume prompts for a password on the first activation after a system boot or reboot.

Use this menu option to create, delete, rename, activate/deactivate, and mount/dismount volumes and to set volume 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. Supply the password on the first volume activate after a system boot or reboot.

Software RAID Management

  • Ins = Create a software RAID (0, 1, or 5)
  • Del = Delete a software RAID device
  • F3 = Expand a RAID device (add segments)
  • F5 = Refresh details of the software RAID device
  • F6 = Restripe (resume restriping for paused RAID 0 or 5 device)
  • F8 = Show pools (list pools on selected RAID 0 or 5; for RAID 1, its single member pool appears in device details)
  • 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.

Create a software RAID 10 device by mirroring software RAID 0 devices. Create a software RAID 15 device by mirroring software RAID 5 devices.

Partition Management

  • Ins = Create an NSS or an iSCSI partition
  • Del = Delete an NSS or an iSCSI partition
  • F3 = Mirror (create a software RAID-1 device)
  • F5 = Refresh details of the partition
  • Enter =Show volumes

Use this option to create and manage NSS partitions and iSCSI partitions. To create iSCSI partitions, the server must run iSCSI target software and be the server you plan to make your iSCSI disk server.
