1. Return DFSMS host control of the 3494 Tape Library to online status by issuing
the following command:
VARY SMS, LIB(libname
2
), ONLINE
2. Confirm that the appropriate drives are online and available by issuing the
following command:
LIBRARY DISPDRV, libname
2
For any drive that is not online, issue the following command:
VARY xxx, ONLINE
3. If the system environment includes JES-3, the library tape drives must be in
normal status. Use of the JES-3 VARY commands for the GLOBAL and all
LOCAL processors may be appropriate.
4. If the system environment includes LEGENT Multiple Image Manager (MIM),
the 3494 Tape Library tape drives must be in normal status. Use the MIM vary
commands on each applicable host.
5.
If the system environment includes a different product, such as Tivoli
®
Storage
Manager or EPIC, use the appropriate commands to ensure normal 3494 Tape
Library and tape drive status.
6. You may retry any pending jobs waiting for a response to an outstanding
WTOR (CBR4196D) message by responding to the host request with an R
( Retry ).
7. If the CHECK-1 occurred while doing cartridge ejects, verify that the last three
volsers placed in either the high-capacity I/O facility or the convenience I/O
station are still present in the DFSMS database. If the volsers are present in the
DFSMS database, the volsers must be inserted through an input station, then
the DFSMS command to eject the volsers needs to be reissued.
This completes the DFSMS recovery procedure. The 3494 Tape Library should now
be ready for submission of tape jobs.
Note: Any tape job that aborted needs to be resubmitted.

or may not display a message. The standby Library Manager displays a message
stating that a switchover is being made, which can take up to ten minutes to
complete.
Note: Some Library Manager recovery operations may takelonger than expected to
complete. Allow sufficient time for the Library Manager to complete its
switchover procedures. Seek assistance before interrupting the Library
Manager recovery operation.
