1.111 NSSMU

Purpose

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

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.

For OES NetWare, you can set up iSCSI partitions using the Partitions option in the main menu in NSSMU. You must have iSCSI target software loaded to make your server an iSCSI disk server. You cannot create iSCSI devices during the initial installation. For more information, see the NW 6.5 SP8: iSCSI 1.1.3 Administration Guide.

For OES NetWare, you can use NSSMU and Novell Remote Manager to create encrypted volumes. Encryption is an optional volume attribute, available only at volume-creation time. An encrypted volume meets the legal standard of making data inaccessible to software that circumvents normal access control, such as if the media were stolen. You cannot create encrypted volumes during the installation. The sys: volume is not eligible for encryption.

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 server if you accidentally delete or rename the sys: volume.

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

Management Options

Function Keys

Description

Device Management

F1 = Help

F2 = Scan for devices

F3 = Initialize device (not for sys:)

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 (Sharable/Not sharable 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. Use the RAID Devices option to create and expand software RAID-0, RAID-1, and RAID-5 devices.

Pool Management

Ins = Create a pool

Del = Delete a pool

F3 = Expand a pool (add segments)

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)

Alt+F8 = Update NDS®/eDirectory™

Enter = Show volumes (on a server or pool)

Use this menu option to create, delete, rename, and expand NSS storage pools to efficiently use all free space in the available devices.

Volume Management

Ins = Create an encrypted or unencrypted volume

Del = Delete a volume

F3 = Rename a volume

F5 = Refresh details of the volume

F6 = Deactivate/Activate an encrypted or unencrypted volume. If encrypted, the volume prompts for a password on the first activate after a system boot or reboot.

F7 = Dismount/Mount a volume

F8 = More (list more options)

Alt+F8 = Update NDS/eDirectory

Enter = Properties (change volume properties)

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, enable the encryption attribute on volume creation. The encryption setting persists for the life of the volume. The encryption password can be up to 16 standard ASCII characters, with a suggested minimum of six. 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 0/5)

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 segments)

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 segment to the RAID.

You can also create a software RAID 10 pool by mirroring a pool on software RAID 0 devices, which must have no physical drives in common. Create a pool on one of the RAID 0 devices, then mirror the pool on up to three software RAID 0 devices, totalling up to four segments for the RAID 10 pool.

Partitions

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.
