Copying a Volume
You can copy a master volume or a snapshot to a new standard volume. The
volume-copy operation takes a snapshot of all data in the source volume and creates
a destination volume that you specify. The destination volume must be in a virtual
disk owned by the same controller as the source volume.
Caution – To avoid data corruption in the destination volume, prepare for the copy
operation as described in Step 1.
To copy a volume:
1. Prepare to copy a master volume or a snapshot as follows:
■ Before copying a master volume:
■ Verify that the snap-pool has space for the temporary snapshot, which is used
to track changes to the master volume while the copy is in progress; see
“Estimating Snap-Pool Size” on page 105. If there is insufficient space, you
can expand the snap pool; see “Expanding a Volume” on page 87.
■ Synchronize the volume’s data with the host either by using a third-party host
utility or by unmounting the volume.
■ Before copying a snapshot’s modified data, either unmount the volume or
otherwise ensure that there is no host or application access to the volume.
■ No preparation is needed to copy a snapshot’s preserved data only.
2. Select Manage > Volume Management > Volume-Copy Services > Volume-Copy.
For each virtual disk, the virtual disk panel shows a status icon; the name, RAID
level, size, number of disk drives, and number of volumes; and utility status, if any.
3. Select the master volume or snapshot that you want to copy.
The selected virtual disk’s volume names, sizes, and types are displayed, and the
amount of free space.
4. Select a destination virtual disk.
5. Type a name for the destination volume.
The name is case sensitive and can include 20 characters, but not comma, quotation
mark ("), or backslash.
