Multiple DFSMShsm host considerations when using the AUDIT command
For the greatest accuracy in a multiple-host HSMplex, with any
AUDIT command other than AUDIT COMMONQUEUE, issue the command from
one host after you have stopped DFSMShsm in the other hosts. For most
users, this is unrealistic even though AUDIT may report discrepancies
due to the concurrent operation of multiple hosts. If you cannot stop
DFSMShsm in the other hosts, use one of the following approaches when
you issue the AUDIT command:
- Run the AUDIT NOFIX command once, and then run it again several days later. Those errors common to both executions are likely to be true discrepancies in the CDSs.
- Execute the AUDIT command from one host immediately after restoring a CDS from backups, before other hosts are started.
- For AUDIT COMMONQUEUE, it is best to issue the command when all hosts are active and connected.
Note: If AUDIT is running and backup of the DFSMShsm control
data sets has started (using BACKVOL CDS command or AUTOBACKUP), all
DFSMShsm functions on the host that started this backup are halted
until the AUDIT function and the backup of the DFSMShsm CDSs have
completed.
