Explanation
An error with the SMSVSAM server has caused DFSMShsm to
lose access to its control data sets. 
Either the
SMSVSAM server did not initialize within the allotted amount of time,
the SMSVSAM server was repeatedly terminating, or DFSMShsm was unable to open
one or more of the CDSs after a server error occurred.
All attempts
to read, write, delete or update control data set records will fail.
Most functions currently being processed will fail. Only those functions
that are allowed to continue while DFSMShsm is in emergency mode will continue
to be processed. To regain access to the control data sets, DFSMShsm must
shutdown and be restarted.
System action
DFSMShsm is placed into emergency and shutdown modes. An abend is issued.
Programmer response
Restart DFSMShsm after it has shut down and the SMSVSAM server has restarted. Examine all DFSMShsm messages associated with the SMSVSAM server error. Issue any FIXCDS commands that are documented in the messages that were received. Perform audit processing if it appears that the failure might have caused inconsistencies between the control data sets and the data that DFSMShsm is managing. For more information, see "DFSMShsm Abnormal End Considerations" in the z/OS DFSMShsm Implementation and Customization Guide.
