the library manager may display one or more of the following screen messages:

Library Manager Action – Library Manager Recovery Begins

(MVS/BLTS Environment)

Single Library Manager Configuration:
For a single library manager
configuration, do the following:
1. Contact host operations and inform them what has occurred at the library
manager.
2. If a BTLS ERA=70 Library Manager Equipment Check occurred, the library
manager automatically attempts to restart itself.
The library manager should begin initial program load (IPL) in about 5 minutes
and may take up to 20 minutes to complete and become active. If, after 5
minutes, there is no change in the System Status messages, or an “Error
recovery in progress” message is not displayed, do a manual restart. Do not
power off the library manager. Press the CTL+ALT+DELkey sequence to
restart the library manager.
This procedure may need to be repeated. If the library manager fails to begin
IPL in 5 minutes, after the second attempt to recover call your next level of
support.
3. If the failure did not cause the Library Manager to automatically restart, perform
the CTL+ALT+DELkey sequence to restart the library manager.
