166 Configuration: Premium Feature—Virtual Disk Copy
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
has been 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:
1
Selecting a source virtual disk from a list of available virtual disks
2
Selecting a target virtual disk from a list of available virtual disks
3
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.
The Operation in Progress icon appears 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 these conditions:
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 appears in the Array Management window. 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.
