Snapshot Tools from the AIX Solution Kit
The Snapshot tools from the AIX Solution Kit are contained within a fileset called
hsg_snapshot.rte. The Snapshot utilities can be accessed through SMIT
through the menu items Applications->Compaq HSG80 Snapshots. Following
is a description of each of the menu items under StorageWorks HSG80 Snapshots
and how to use them.
List Snapshot Units
The menu item lists all the Snapshot units on a particular HSG80. You have to
specify which communications device you wish to use when you list the Snapshot
units. This allows you to specify which subsystem you wish to list. The World
Wide Node Name of the subsystem attached to your server is listed along with the
communications device.
Automatic Snapshot
This automatically creates a Snapshot of a particular HSG80 hdisk device on your
system. The only parameter that you need to specify is which hdisk you wish to
create a Snapshot of. The utility automatically creates either a JBOD disk or a
Stripeset disk to house the Snapshot data and then create the actually Snapshot
itself. You can then issue a
cfgmgr -v command to configure the new device.
If the Snapshot fails to be created, the following could be the cause:
■ There is not enough space left on the HSG80.
■ The Stripeset could not be created.
■ You have reached the maximum allowed number of Snapshots.
■ There was a communications failure with the HSG80.
Manual Snapshot
This method of Snapshot creation allows you to choose the parameters you wish
to use to create the Snapshot. You first pick the communications device to use the
same way as you do when you list the Snapshot units on a particular subsystem.
You then fill in the following parameters:
1. Unit to Snapshot—The unit name on the subsystem that you wish to make a
Snapshot of.
