Enabling XBM to process traditional hardware snapshots

Set up the hardware environment.

Hardware snapshots rely on user-controlled mirrored pairs or data set replications to obtain a preimage of registered data sets. Mirrors must be synchronized with the source volume before the snapshot can begin.

Consult your storage device documentation or vendor to ensure that your pairs are set up and working correctly before beginning a hardware snapshot.

Setting-up-the-hardware-environment

Configure the SSI component.

In the ISPF interface, set SSI options to configure the SSI component.

The SSI options control such things as:

• The display of hardware devices
• Whether the SSI component is enabled
• Whether to allow data set snaps or volume mirror splits
• Data set options
• Support of remote hardware

Setting-SSI-options-for-hardware-snapshots

Create a snapshot utilities template in a management set to define snapshot attributes.

Through the ISPF interface, create a management set to contain the snapshot template that you want to use.

In the snapshot template, control whether hardware snapshots can be performed and other hardware-specific options.

Creating-a-snapshot-template-for-a-hardware-snapshot

Activate the snapshot template.

Through the ISPF interface, activate the management set that contains the snapshot template that you want to use.

Activating-the-management-set

Run the utility job.

Initiate your utility job by following the instructions provided in the utility documentation.

When the snapshot job begins, XBM first attempts a hardware snapshot to provide preimages to the snapshot utility. If the appropriate mirrored pair or data set snapshot capability is unavailable and you have specified a software cache, XBM falls back to a software snapshot to successfully complete the snapshot job.

Review the status of the snapshot job.

Review the messages that XBM generated.
