Using the Virtual Disk Copy Feature
79
The following steps show the general process for creating a virtual disk copy:
1 Enable the Virtual Disk Copy feature.
2 Determine candidates for a virtual disk copy.
3 Create the target virtual disk and source virtual disk for a virtual disk copy.
Enabling the Virtual Disk Copy Feature
The first step in creating a virtual disk copy is to make sure the feature is
enabled on the storage array. You need a feature key to enable the feature. To
enable the feature key file, use the command:
enable storageArray feature file=" filename "
where the file parameter is the complete file path and file name of a valid
feature key file. Enclose the file path and file name in quotation marks (" ").
Valid file names for feature key files usually end with a .key extension.
Determining Virtual Disk Copy Candidates
All virtual disks might not be available for use in virtual disk copy operations.
To determine which candidate virtual disks on the storage array can be used
as a source virtual disk, use the
show virtualDiskCopy sourceCandidates
command. To determine which candidate virtual disks on the storage array
can be used as a target virtual disk, use the show virtualDiskCopy
targetCandidates command. These commands return a list of the expansion
enclosure, slot, and capacity information for source virtual disk and target
virtual disk candidates. You can use the show virtualDiskCopy
sourceCandidates and the show virtualDiskCopy targetCandidates
commands only after you have enabled the virtual disk copy feature.
Creating a Virtual Disk Copy
NOTICE:
A virtual disk copy overwrites data on the target virtual disk. Ensure that
you no longer need the data or have backed up the data on the target virtual disk
before starting a virtual disk copy.
When you create a virtual disk copy, you must define which virtual disks to
use for the source virtual disk and target virtual disks. Define the source
virtual disk and target virtual disk by the name of each virtual disk. You can
