Dell PowerEdge RAID Controller 9 User’s Guide H330, H730, and H830

Virtual disk migration

The PERC 9 series supports migration of virtual disks from one controller to another without taking the target controller offline. The controller can import RAID virtual disks in optimal, degraded, or partially degraded states. You cannot import a virtual disk that is offline. Disk migration pointers:
  • Supports migration of virtual disks from PERC H310, H710, H710P, and H810 to PERC 9 series
  • Supports migration of volumes created within PERC 9 series
  • Does not support migration from PERC 9 series to H310, H710, H710P, H810
NOTE:The source controller must be offline prior to performing the disk migration.
NOTE:Disks cannot be migrated to older generations of the PERC cards.
NOTE:Importing secured virtual disks is supported as long as the appropriate Local Key Management (LKM) is supplied or configured.

When a controller detects a configured physical disk, it flags the physical disk as foreign, and generates an alert indicating that a foreign disk was detected.

CAUTION:Do not attempt disk migration during RLM or online capacity expansion (OCE). This causes loss of the virtual disk.
