Explanation
While performing an XCF function
for Secondary Host Promotion or CDS Backup serialization notification,
an error occurred during the processing of an DFSMShsm XCF member event. The
possible values of
return-code are:
- 2
- This host was attempting to take over the responsibilities for
host hostid. Host hostid may
not be able to be demoted.
- 4
- This host was attempting to record the host ID of the host for
which it had been promoted. See message ARC1522I to determine which
host that was. This host will be unable to determine when the demoted
host is ready to take back its responsibilities. Thus, it will perform
those responsibilities until it is disabled.
- 6
- This host was attempting to notify promoted host hostid that
it has been demoted. If host hostid is in emergency
mode but changes to noemergency mode without being shutdown, then
it will continue to function as a promoted host. Host hostid should
be restarted.
- 8
- This host was attempting to demote itself, but could not. It will
continue as a promoted host until it is restarted.
- 10
- This host was unable to take back the primary or SSM host responsibilities,
or both, for which it was demoted. If the promoted host has already
been demoted, then no host will be performing the primary or SSM responsibilities,
or both, of this host. This host should be restarted.
- 12
- This host was attempting to signal that it is in emergency mode.
If it is a primary, SSM, or promoted host, its responsibilities will
not be taken over by another host.
- 14
- This host was attempting to signal that it is no longer in emergency
mode. If it is a primary or SSM host, it may not be able to take back
its responsibilities.
- 16
- This host was attempting to update its status as an SSM host.
This will cause miscellaneous problems.
- 18
- This host was attempting to disassociate itself from XCF. If it
is a primary or SSM host, then it may be unexpectedly demoted.
- 20
- An internal DFSMShsm error
occurred while processing DFSMShsm XCF member events. One or more
events will be missed.
- 22
- An error occurred while querying XCF.
- 24
- This host was attempting to indicate that it is no longer promoted
for the demoted host hostid. Until demoted host hostid restarts,
no host will be able to take over the functions for which this host
had been promoted.
- 26
- An XCF failure occurred during CDS Backup as this host was trying
to update its XCF User State Field to indicate to other hosts in this
HSMplex that CDS backup either needed their functions to release ARCGPA/ARCCAT
or to stop releasing ARCGPA/ARCCAT.
- 28
- An XCF failure occurred during CDS Backup processing as this host
was trying to disassociate from the XCF group. An attempt was made
to notify other hosts in the same HSMplex that the CDS Backup host
no longer needs their functions to release ARCGPA/ARCCAT by attempting
to disassociate from the XCF group. Other DFSMShsm hosts in the same HSMplex
will continue to release the ARCGPA/ARCCAT resource unnecessarily
and as a result, might experience poor DFSMShsm performance.
System action
DFSMShsm continues processing.
Programmer response
Contact IBM® support
to determine the cause of the unsuccessful completion of the XCF function.
- 26
- No response necessary unless an ARC1524I RC28 is issued.
- 28
- If the poor DFSMShsm performance
is beyond acceptable limits, DFSMShsm on the CDS backup host must be
restarted.
