6.4 Viewing Device Details

NSSMU allows you to view the following information about each device:




Specifies the Linux device node name in the /dev directory.

Examples: sda, sdb, sdc, sdd, and so on


Specifies the major and minor number assigned to a block device on the server.

Example: 8:0, 8:16, 8:32, 8:48

Partitioning type

Specifies if the DOS or GPT partitioning scheme is used to format the device. A device that is not partitioned is reported as Uninitialized.

A device that contains a non-mirrored Novell Cluster Services split-brain detector (SBD) partition is typically formatted as MS-DOS. A device that contains a mirrored SBD partition has a partition type of NA (not applicable) because it is a RAID 1 device.


  • Uninitialized: The device is not partitioned.

  • DOS: The device is partitioned in MS-DOS format.

  • GPT: The device is partitioned in GUID Partition Table format.

  • CSM: The device contains a legacy Cluster Segment Manager partition that was created by using the Enterprise Volume Management System (EVMS) on an OES 2 cluster node, and has been imported for use on OES 11 (or later) cluster nodes.

  • LVM2: The entire device is an LVM2 volume group that contains an LVM2 logical volume. For example, the device is used for a clustered LVM2 volume group and logical volume.

  • NA: The device is an NSS or SBD RAID 1 mirrored device that does not have a partitioning scheme.


Specifies whether the device is an NSS software RAID device.

Values: Yes or No


Specifies whether the device contains an LVM volume group.

Values: Yes or No


Specifies the total amount of space available on the device.

Partitioned space

Specifies the amount of space in use on the device.

Unpartitioned space

Specifies the amount of free unpartitioned space available on the device. For MSDOS devices, free space includes unallocated space in an extended DOS partition.

Shareable for clustering

The device can be used for shared Novell partitions. Use with Novell Cluster Services SBD partitions and cluster-enabled NSS pools. The status is stored on a 4 KB partition on the device.

Values: Yes or No (default)
