Missing Virtual Disk

What Caused the Problem?

The storage array has detected that the physical disks associated with a virtual disk are no longer accessible. This can be the result of removing all physical disks associated with a disk group or a loss of power to one or more enclosures. The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

 Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.
