From this result, D001 and D102 are the target drives for copy in the storage
system.
4. If the copy is to be a Snapshot, skip to Step 5, otherwise follow the Clone
procedure described in this guide. Repeat the procedure for each target drive.
As mentioned before, the hdisks associated with the storage system drives and
targeted for Clone copy can remain available and logical volumes mounted in
AIX. However, no AIX operation that results in a write to the drives should be
allowed. When the Clone is complete, go to Step 6.
5. For Snapshot, the HSG80 controller must loaded with “S” type firmware
before this function can succeed. Select and initialize the disk devices in the
storage system having the same capacity as the target drives. Create a
one-disk mirror container for each selected drive. Using a terminal attached to
the HSG80 controller serial interface, add the drives as Snapshot units using
the following CLI command construct:
ADD SNAPSHOT <New Unit Number> <Mirror Container Name> <Target
Disk Unit>
6. Depending on the storage system configuration with the host or hosts, it may
be necessary to control or activate host access to the new drive. Refer to the
section, "Restricting Host Access in Multiple-Bus Failover Mode", page 55.
Once this has been addressed, the new drives should be available for AIX use.
7. Run
cfgmgr on the AIX system after which a new set of hdisks equal to the
number of target hdisks should become available.
8. The new hdisks can be verified as copies of the originals by examining the
respective hdisk physical volume IDs (PVID). To do this, issue the
lspv AIX
command.
The following is an example:
# lspv
hdisk0 000518660c11216F rootvg
hdisk1 003b5075af8b1c4e datavg
hdisk2 003b50756c0fc93e datavg
hdisk3 003b5075af8b1c4e none
hdisk4 003b50756c0fc93e none
