• 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.
