The ISM server tracks the backed-up data in the ISM catalog. You can re-create entries in the ISM catalog for expired save sets and for volumes that have been deleted from the ISM catalog from the command line.
After you re-create entries in the ISM catalog, you can use ON–Bar to recover the data. For details on how to use the ISM command-line utilities, see Appendix A. ISM Command-Line Utilities.
Before you use ON–Bar to recover data, use the ism_catalog -recreate from command to re-create the entries in the ISM catalog in the following situations:
After a save set has expired, you need to re-create its entry in the ISM catalog before you can restore the data with ON–Bar.
When the Recycling status for a storage volume has changed to Eligible, the retention periods for all the save sets on the storage volume have expired. You need to re-create the entries in the ISM catalog before you can restore the data with ON–Bar.
If you remove a storage volume from the ISM catalog, but the data on the volume is still intact, you can re-create the entries in the ISM catalog and then use ON–Bar to recover the data on the volume.
If the ISM server is on UNIX, you must have root privileges to execute the ism_catalog command. If the ISM server is on Windows, you must be a member of the Informix-Admin group.
ism_catalog -recreate_from deviceWhen you recover a storage volume in this way, ISM automatically marks the Backup status for the volume as Disabled to ensure that no new data is written to the storage volume. To protect the volume from automatic recycling, change the recycling status of the volume to Manual. ISM does not automatically recycle a volume marked Manual.
