Commands to Offline Devices
The IBM® DASD
subsystems report subsystem level changes and asynchronous message
availability on any device in the subsystem. A device can be online
or offline to CP. You can enter the following commands to both online
and offline devices:
- QUERY CACHE
- SET CACHE
- QUERY DASDFW
- SET DASDFW
- DISCARD
- QUERY DUPLEX
- QUERY PINNED
- QUERY RSAW.
Note: For the QUERY CACHE and SET CACHE commands, offline device support
only applies to devices attached to the IBM DASD subsystems.
