Virtual disk migration

The Shared PERC 8 card 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.
The Shared PERC 8 card does not support virtual disk migration:
  • Where the virtual disk is in a failed state.
  • When the virtual disk is removed while the source system is turned on.
  • From any other PERC cards such as PERC H310, H700, H710, H800, and H810.
The Shared PERC 8 card supports virtual disk migration:
  • From a similar Shared PERC 8 card.

  • From the Single Shared PERC 8 card configuration to the Fault Tolerant Shared PERC 8 card configuration, but not from a newer firmware version to an older firmware version system.

  • From another system's Shared PERC 8 controller when the target system is either turned on or off.
  • NOTE: When a controller detects a physical disk with an existing configuration, it flags the physical disk as a foreign disk and generates an alert indicating that a foreign disk was detected.
