Before running BACKUP SYSTEM

Certain activities might be required before you run the BACKUP SYSTEM utility, depending on your situation.

To run BACKUP SYSTEM, ensure that the following conditions are true:

  • The data sets that you want to copy are SMS-managed data sets.
  • You have disk control units that support ESS FlashCopy®.
  • Any needed copy pools are defined. See Copy pools.
  • The ICF catalog for the data must be on a separate volume than the ICF catalog for the logs.
  • An SMS backup storage group is defined for each storage group in the copy pools.
  • Start of changeBefore defining the copy pool or pools, ensure that all members in a data sharing group are in an active, quiesced, or deactivated status. You can use the DISPLAY GROUP command to check member status. If a member is in a failed state, correct the error that caused the failure and restart the failed member. If a member is in an unknown state ('********'), contact IBM® Support.End of change
