Disk roaming

Disk roaming is when a physical disk is moved from one cable connection or backplane slot to another on the same controller. The controller automatically recognizes the relocated physical disks and logically places them in the virtual disks that are part of the disk group. If the physical disk is configured as a non–RAID disk, then the relocated physical disk is recognized as a non–RAID disk by the controller.

CAUTION:It is recommended that you perform disk roaming when the system is turned off.
CAUTION:Do not attempt disk roaming during RAID level migration (RLM) or online capacity expansion (OCE). This causes loss of the virtual disk.
