The ism_catalog command enables you to re-create entries in the ISM catalog for a volume that has been removed from the ISM catalog, find the ISM server bootstrap, create a new ISM bootstrap, and recover the entire ISM catalog.

| Element | Purpose | Key Considerations |
|---|---|---|
| -server hostname | Specifies the name of the computer on which the ISM server is running | If you omit this option, this command looks first for an ISM server on the local computer and then for the first ISM server to respond over the network. |
| -recreate_from device | Re-creates the ISM catalog directly from the storage media | Use to recover expired save sets or storage volumes that are eligible for recycling. To add the volume to a different volume pool from the one to which it originally belonged, you can use the -pool option. |
| -create_bootstrap | Creates a new bootstrap for this ISM server | This command writes a new bootstrap for the ISM server. |
| -pool pool | Designates a volume pool to which to write recovered data or a new bootstrap | None. |
| -find_bootstrap device | Scans the media looking for the start of the ISM server
bootstrap save set
After the media has been scanned, prints the save-set ID (ssid) and tape file location of the most recent bootstrap save set. |
You need the bootstrap save set for disaster recovery. You use the bootstrap information to recover the ISM catalog directly from storage media with the ism_catalog -recover command. You then use Volume Inventory or the ism_show -volumes command to determine which volumes you want ON–Bar to restore. |
| -recover | Recovers the ISM catalog from storage media when the catalog has been lost or damaged | This command overwrites the existing ISM catalog. Before you execute this command, you need the bootstrap save-set ID that you obtained from the most recent bootstrap printout or from the ism_catalog -find_bootstrap command. |
