4.4.6.3 Logical Drive Deletion
This option deletes a logical drive. The RAID controller supports the
ability to delete any unwanted logical drives and use that space for a new
logical drive. The configuration utility provides a list of configurable arrays
where there is a space to configure. You can have an array with multiple
logical drives and delete a logical drive without deleting the whole array.
Note: The deletion of the logical drive can fail under certain
conditions: During a rebuild, initialization or check
consistency of a logical drive, if that drive has a higher
logical drive number than the drive you want to delete.
4.4.6.4 Drive Migration
Drive migration is the transfer of a set of hard drives in an existing
configuration from one controller to another. If you put the hard drives on
a new controller, the controller must have a clear configuration. The
drives must remain on the same channel and must be reinstalled in the
same order as in the original configuration.
In addition, the drives must be on the same channel/target as they were
on the previous controller to keep the same configuration.
Note: For more information and the procedure for drive migration,
refer to
Section 3.7, “Performing Drive Migration,” page 3-29 .
