Virtual Disk Copy and Modification Operations

If a modification operation is running on a source virtual disk or a target virtual disk, and the virtual disk copy has a status of In Progress, Pending, or Failed, the virtual disk copy does not take place. If a modification operation is running on a source virtual disk or a target virtual disk after a virtual disk copy is created, the modification operation must complete before the virtual disk copy can start. If a virtual disk copy has a status of In Progress, any modification operation does not take place.

Create Copy Wizard

The Create Copy Wizard guides you through:

•Selecting a source virtual disk from a list of available virtual disks.

•Selecting a target virtual disk from a list of available virtual disks.

•Setting the copy priority for the virtual disk copy.

When you have completed the wizard dialogs, the virtual disk copy starts, and data is read from the source virtual disk and written to the target virtual disk.

Operation in Progress icons are displayed on the source virtual disk and the target virtual disk while the virtual disk copy has a status of In Progress or Pending.

Failed Virtual Disk Copy

A virtual disk copy can fail due to:

•A read error from the source virtual disk.

•A write error to the target virtual disk.

•A failure in the storage array that affects the source virtual disk or the target virtual disk.

When the virtual disk copy fails, a critical event is logged in the Event Log, and a Needs Attention icon is displayed in the AMW. While a virtual disk copy has this status, the host has read-only access to the source virtual disk. Read requests from and write requests to the target virtual disk do not take place until the failure is corrected by using the Recovery Guru.
