13.4 Deleting an NSS Partition

Deleting a partition results in data loss. We recommend that you delete the storage structure that uses the partition instead of deleting the partition itself.

13.4.1 Deleting Partitions in a Pool

You cannot shrink the size of a pool by deleting its partitions. Use the Pools page in iManager or NSSMU to delete the pool. For information, see Section 16.6, Deleting a Pool.

13.4.2 Deleting Partitions in an NSS Software RAID Device

You can delete all of the partitions in a software RAID device by deleting the software RAID. For information, see Section 14.16, Deleting a Software RAID Device.

For NSS software RAIDs that provide fault-tolerance, there is limited support for deleting individual partitions used in the RAID.

NSS Software RAID

Delete a Partition (Yes/No)




Delete the RAID to remove its partitions.

RAID 1 (mirror)


Delete the RAID, or delete all but one partition.



Delete the RAID, or delete only one failed partition at a time to repair and restore the RAID. See also Section 14.15, Replacing a Failed Segment in a Software RAID.

For NSS software RAID devices, use the Software RAIDs page in iManager or NSSMU to access and delete its partitions.

Using iManager to Delete a Partition in a Software RAID

The Storage plug-in to iManager does not allow you to delete partitions from the Partitions page because it is designed to abstract all partition management. To delete a single partition in a software RAID 1 or RAID 5 device:

  1. In iManager, click Storage > Software RAIDs.

    For instructions, see Section 10.1.5, Accessing Roles and Tasks in iManager.

  2. Select the server that you want to manage.

    For instructions, see Section 10.1.6, Selecting a Server to Manage.

  3. In the Software RAIDs list, select the software RAID 1 or RAID 5 device you want to manage.

    Wait for the page to refresh and display the details.

  4. Click the View Partition Details icon to open the Partitions page for the selected software RAID.

  5. Select a partition, then click Delete to delete the partition and its contents.

Using NSSMU to Delete a Partition in a Software RAID

NSSMU allows you to delete any NSS partition directly from the Partitions page.

  1. In NSSMU, select Partitions.

  2. Select the partition you want to delete.

  3. Click Delete to delete the partition and its contents, then click OK to confirm deletion.
