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 10-byte LBA format. This means that a logical drive can have up to 4 billion address blocks or sectors.

Multiply the number of blocks by the sector size to find the capacity of a logical drive:

4,000,000,000 blocks x 512 bytes per sector = 2,048,000,000,000 bytes of data for a 2TB drive.

Note that you cannot change the size of the sectors nor can you increase the number of address blocks above 4 billiion.
