Library Manager Failure Recovery Procedures
Notes:
1. This procedure is designed for the recovery of DFSMS/MVS or MVS/BTLS host
sessions. If you are using any other host platform, contact your software
provider before continuing with this procedure.
2. These procedures apply to both single library manager and HA1 (dual library
manager) configurations. In a dual library manager configuration, these
procedures apply to the activation of the standby library manager when the
active library manager fails.
3. Host actions may include varying the library online after a short delay for the
conditions that restart the library manager. Host tape operations or short jobs
may have to be resubmitted and operator actions from the Library Manager
console may require restart.
When a failure occurs in the library manager from either a CHECK-1 or a processor
exception, or when the library manager experiences certain hardware failures,
perform the following procedures to recover host operations. These recovery
procedures allow recovery from many different scenarios. These steps must be
followed in the exact sequence to achieve a complete recovery.
Throughout the recovery procedures, the operator is directed to perform certain
actions at either the library manager or at the host operating console. It may be
helpful to have two people perform the various tasks involved in this procedure due
to locations of the library.
For recovery procedures of DFSMS/MVS, see “Library Manager Failure in a
DFSMS/MVS Environment”. For recovery procedures of MVS/BTLS, see “Library
Manager Failure in an MVS/BTLS Environment” on page 265.
Library Manager Failure in a DFSMS/MVS Environment
The following failure conditions cause the operator to initiate this procedure:
