• 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. 

specifies that a backup operation is to be performed. 

optionally, specifies that a backup is to be run on a control data set. If CDS is not 
specified, the BACKup utility backs up the CDS containing the most updates.
