CANNOT MANAGE MVS AUTOSWITCHABLE DEVICE dddd

Reason:

An attempt was made to start CA MIA or it went through re-synchronization processing (due to the CA MIA RESYCH command or z/OS dynamic I/O reconfiguration). Device dddd was to be managed by CA MIA, but it is defined to z/OS as autoswitchable. Because CA MIA was unable to turn off the z/OS autoswitching for this device (most likely because it was online), it cannot be managed.

If CA MIA was being started, then it will not initialize. If it was processing a RESYNCH command, then CA MIA will not resynchronize. CA MIA will resynchronize if it was processing a z/OS dynamic I/O reconfiguration, but CA MIA will not manage device dddd.

Action:

Vary device dddd offline and vary it non-autoswitchable to z/OS. Then restart CA MIA or issue the RESYNCH command.
