Important
•The Target logical drive may require more disk drives than the Source logical drive
•If the Target logical drive requires an EVEN number of disk drives but the Source logical drive has an ODD number, ADD a disk drive as part of the migration process
•You cannot reduce the number of disk drives in your logical drive, even if the Target logical drive requires fewer disk drives than the Source logical drive
•RAID 1 (mirror) works with two disk drives only
•You cannot migrate a logical drive when it is Critical or performing activities such as Synchronizing, Rebuilding and
PDM
•RAID level migration is not possible to or from JBOD
Ranges of Disk Array Expansion
There are limitations to how large you can expand a logical drive, depending on the size of your current logical drive.
The current SCSI and Fibre Channel HBA cards and PC Operating Systems support a
