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) con®gurations. In a dual library manager con®guration, 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 ªLibrary Manager Failure in a

DFSMS/MVS Environmentº. For recovery procedures of MVS/BTLS, see ªLibrary

Manager Failure in an MVS/BTLS Environmentº on page 265.
