Array Configuration Utility (ACU)
106 Modular SAN Array 1000 User Guide
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.
■ Migrate the RAID level or stripe size of an existing logical drive.
■ Extend an existing logical drive on the same array, if the operating system
allows logical drive extension.
To delete a logical drive:
1. Click Delete logical drives and click Begin.
2. Select the logical drives that you want to delete and click Next.
A warning screen is displayed to remind you that you will lose all data on the
logical drive.
3. Click Delete to continue and click Finish to accept the changes.
4. Click Save to apply the changes to the system and click OK on the
confirmation alert.
Expand Array
Note: Expand array 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
physical 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.
■ Migrate the RAID level or stripe size of existing logical drives.
■ Extend existing logical drives on the array, if the operating system allows
logical drive extension.
