configuration, do the following:
v Contact host operations and inform them what has occurred at the library
manager.
– If a CHECK-1 or a processor exception occurred, the library manager
automatically attempts to restart itself.
Note: If, after 30 minutes, there is no change on the System Status screen

manager. Press the CTL+ALT+DEL key sequence to restart the library
manager.
This procedure may need to be repeated. If, after the second attempt
to recover the library manager, there is no response, call your next
level of support.

manually by doing the following:
