13.4 Viewing Details of a Software RAID Device

You can view the following information about a selected software RAID device:

Table 13-3 Explanation of Details for a Software RAID Device

Software RAID Device Detail

Description

Name

On Linux, this is the administrator-specified descriptive name for the RAID. In iManager, if you do not specify a name for the device at create time, a name is autogenerated in the format of RAID <type> Device <number>.

On NetWare®, this is the device ID assigned by the operating system, such as 0x2. This name appears in the Devices list.

Device

On NetWare, this field displays the RAID type and the number of member devices.

Description

On NetWare, this is the administrator-specified descriptive name for the RAID. In iManager, if you do not specify a name for the device at create time, a name is autogenerated in the format of RAID <type> Device <number>.

Module ID

The Novell driver identification number for the module; it indicates what type of driver you are using.

Adapter

The sequential number registered for the adapter; it indicates which drive is on which adapter.

GUID

The Global Unique Identifier number that NSS assigns to the storage object. This number is necessary so your file system can locate the specific device.

Share State

Shareable for Clustering or Not Shareable for Clustering. The share state can be modified on the Devices page.

If you assign partitions to a software RAID device, all the devices for those member partitions must either be marked as Shareable for Clustering, or all marked as Not Shareable for Clustering.

Capacity

The total storage capacity of the device that is reserved for data storage. For a RAID 0, the storage capacity is equal to the sum of its partitions. For RAID 1, the storage capacity is equal to a single partition size; the duplicate partitions are mirrors. For RAID 5, the storage capacity is equal to the sum of its partitions minus one partition for parity.

Used Space

The amount of space on the device that is currently in use by NSS partitions.

Free Space

The total amount of space on the device that is currently not in use.

Partitions

Lists the member partitions of the selected software RAID device in a drop-down list. To view a partition’s details, select the partition in the drop-down list, then click the View Details icon.

Partition Size

The size (in MB) of partitioned space per drive.

Stripe Size

The maximum size (in KB) of a data write, as configured for a RAID 0 or RAID 5 device.

Number of Partitions

The total number of partitions in the selected software RAID device.

Status

Shows the status of a RAID 1 (mirrored) device’s partitions: In Sync or Out of Sync.

Viewing Details in iManager

  1. In iManager, click Storage > Software RAIDs.

    For instructions, see Section 9.1.3, Accessing Roles and Tasks in iManager.

  2. Select a server in the eDirectory tree where you are logged in.

    For instructions, see Section 9.1.4, Selecting a Server to Manage.

    This opens the Software RAIDs Management page.

    The Software RAIDs list displays the virtual RAID devices on the selected server. The list might include any RAID O, RAID 1, or RAID 5 devices that you created. It does not list any hardware RAID devices in this list.

  3. Select a virtual storage device in the Software RAIDs list to view information about that device, then wait for the page to refresh.

Viewing Details in NSSMU

  1. In NSSMU, select Software RAIDs.

  2. Select the RAID device you want to manage and wait for the information to be displayed.
