StorageTek 6 manual Backup, Syntax, Utility Name, Parameters, BACKup

Backup

•Avoid running the SET utility.

•Avoid running the Scratch Update and Scratch Redistribution functions during this time.

•Take all HSCs down prior to the link being restored.

Special considerations after the link is restored include:

•Avoid restoring CDS copies from backups taken while the link is down. If a restore of the CDS(s) is necessary only on one side of the link, make sure that only the CDS(s) on that side is restored.

Do this by including only /FILE statements for the data sets on the side of the link to be restored. Do not restore all CDS copies from a backup taken while the link is down.

•After the link is restored, ALL HSCs should remain down for backup/restore.

•Run BACKup. OPTion(Analyze) must be used.

•If you know which CDS has had the most processing occur after the link was disrupted, use the CDS keyword to select that CDS for backup.

•Once backup is completed, restore the control data sets. Do not apply journals.

•Reinitialize the HSCs.

•When the ACSs are available, start the SLUADMIN program using the SLSAUDIT data set from the restore as input.
