Delete logical drives
This task deletes the selected logical drive and converts it into unused drive space. You can then use this unused drive space to:
•Create new logical drives ("Create a logical drive" on page 22).
•Migrate the RAID level or stripe size of an existing logical drive ("Migrate a logical drive" on page 25).
•Extend existing logical drives on the same array ("Extend logical drive" on page 25), if the operating system allows logical drive extension.
To delete a logical drive:
1.Click Delete logical drives, and then click Begin.
2.Select the logical drives that you want to delete, and then click Next. ACU displays a warning screen to remind you that you will lose all data on the logical drive.
3.Click Delete to continue, and then click Finish to accept the changes.
4.Click Save to apply the changes to the system, and then click OK on the confirmation alert.
Expand Array
NOTE: The Expand Array task is listed only if there is an unassigned physical drive on the controller. The unassigned drive must also have a capacity no less than that of a drive in an existing array. If these conditions are not fulfilled, install at least one suitable drive on the controller, and then click Refresh.
This task increases the storage capacity of an existing array. You can use the additional storage space to:
•Create new logical drives ("Create a logical drive" on page 22).
•Migrate the RAID level or stripe size of existing logical drives ("Migrate a logical drive" on page 25).
•Extend existing logical drives on the array ("Extend logical drive" on page 25), if the operating system allows logical drive extension.
IMPORTANT: An array expansion, logical drive extension, or logical drive migration takes about 15 minutes per gigabyte, or considerably longer if the controller does not have a
1.Click Controller Settings, and verify that the Expand Priority setting is acceptable.
2.Back up all data on the array. Although array expansion is unlikely to cause data loss, observing this precaution provides additional data protection.
3.Click Expand array, and then click Begin.
4.Choose the array that you want to expand, and then click Next.
5.Select the physical drives that you want to add to the array, and then click Next.
6.Click Finish to accept the changes.
At this point (before clicking Save in the next step), you can create logical drives on the unused space created by the expansion. You can also arrange to expand another array on the same controller by repeating the previous steps. However, the controller can expand only one array at a time. Remaining array expansions are queued.
7.Click Save.
