Manual recovery

When manual recovery is required, each subsystem request that results in I/O to the control data set fails. For requests that can be retried, DFSMSrmm issues WTOR EDG4001D or EDG8008D.

When you perform manual recovery because the control data set is no longer valid, restore the control data set using the most recent backup copy of the control data set. Forward recover the control data set to the point of failure by using the latest control data set backup and the applicable journal backups that are concatenated with the active journal. See Restoring the control data set with forward recovery for information. If manual recovery is required because the control data set is full or for some other reason where the control data set information is valid except for the most recent failed record updates, use the current control data set for recovery rather than a backup copy. When you use the current control data set for recovery, you do not need to perform forward recovery because DFSMSrmm restart performs automatic forward recovery. Also do not run the EDGUTIL utility against the control data set before you resume DFSMSrmm operation.

Use one of these methods to perform manual recovery by using the current control data set.

Run the EDGBKUP utility with PARM='RESTORE' to use the active journal to forward recover the current DFSMSrmm control data set. If processing is successful, the control data set information is correct. See Forward recovering the control data set.
Run the EDGBKUP utility with PARM='BACKUP(REORG)' to reorganize the current control data set and reclaim enough free space to enable processing to continue. See Reorganizing the control data set. To correct the control data set information, refresh the DFSMSrmm started task, and attempt automatic forward recovery.
Use IDCAMS REPRO to copy the contents of the current control data set to a new, larger control data set. Create a new EDGRMMxx parmlib member to define data set name for the new control data set. To correct the control data set information, refresh the DFSMSrmm started task, and attempt automatic forward recovery.
Run EDGBKUP with PARM='RESTORE' to use the latest control data set backup, and the applicable journal backups that are concatenated with the active journal to forward recover. If processing is successful, the control data set information is correct. See Restoring the control data set with forward recovery.

Manual recovery requires operator intervention. See z/OS DFSMSrmm Managing and Using Removable Media for operator procedures for information about stopping, quiescing, and restarting the DFSMSrmm subsystem. After manual recovery completes, the operator can reply 'RETRY' or 'CANCEL' to the EDG4001D and EDG8008D WTORs. These requests fail and must be rerun or reissued after manual recovery:
