Output media error handling

Class transitions may only be directed to DASD, via the SMS ACS routines.

You can use both tape and DASD as migration devices concurrently. During such an operation, if migration to either tape or DASD is ended because of an error condition, a message is issued, but migration continues to the device type that is not affected by the error condition. A highlighted message is sent to the operator’s console to inform the operator of the error condition. DFSMShsm does not remove this message from the console; the operator must issue a console command to remove it.

After correcting the error condition that caused the migration to tape or DASD to end, the operator can allow DFSMShsm to resume migration to the device that was in error by issuing one of the following commands:

RELEASE MIGRATION(AUTO)
RELEASE MIGRATION
ADDVOL (for a volume of the device type in error)

If error conditions make both tape and DASD unavailable as migration targets, migration processing ends, a message is issued to the operator, and migration is held.
