If the snapshot is of a stripeset, create a stripeset consisting of each of the
constituent snapshot disks:
CLI> ADD STRIPESET stripeset-name snapshot-disk-name-1 snapshot-disk-name-2
If the snapshot is of a simple disk or a simple mirrorset, the snapshot disk is
used as a simple disk device.
2. Initialize the snapshot stripeset or device using the NODESTROY option.
Only initialize the top storageset on which you are going to add the unit. If
you copied a stripeset or striped mirrorset unit, initialize the stripeset created
in step 1 above. If you copied a simple disk or mirrorset unit, initialize the
simple disk unit that resulted.
If you are initializing a stripeset or striped mirrorset, specify the same
chunksize as that on the original stripeset or striped mirrorset.
CLI> INITIALIZE container-name NODESTROY CHUNKSIZE= n
3. Add the host-visible unit with an ADD UNIT command.
6.11 Mirrorset Command Overview
The sections that follow describe mirrorset procedures, commands, and qualifiers.
6.11.1 Creating a Mirrorset
Enter the following commands to create a mirrorset:
1. Add the disks to be used for the mirrorset (unless they have already been
added):
CLI> ADD DISK DISK120 1 2 0 NOTRANSPORTABLE
CLI> ADD DISK DISK220 2 2 0 NOTRANSPORTABLE
CLI> ADD DISK DISK320 3 2 0 NOTRANSPORTABLE
For the best performance and data protection, your mirrorset members should
reside on different ports.
2. To create your mirrorset:
CLI> ADD MIRRORSET MIRR1 DISK120 DISK220 DISK320
CLI> INITIALIZE MIRR1
CLI> ADD UNIT DO MIRR1
3. To display all of the information about your newly created mirrorset:
CLI> SHOW MIRR1
4. To display all of the information about all of the mirrorsets known to your
controller:
CLI> SHOW MIRRORSETS FULL
