CP ATTACH/DETACH FAILED DURING ASYNCHRONOUS PROCESSING

Reason:

This message occurs only in a system where the CP ATTACH and DETACH commands are processed asynchronously. A CP ATTACH/DETACH command is issued on behalf of a CA MIA for z/VM user who issues an MI ATTACH/DETACH command. If the CP ATTACH or DETACH command is accepted but the device is not attached or detached within a reasonable period, CA MIA for z/VM assumes that the ATTACH or DETACH request failed.

Notes:

• For ATTACH commands, this error may be issued if the user to which the drive is attached detaches the drive immediately after the attach completes.
• For DETACH commands, this error may occur if the device is attached to the same user or a different user immediately after the device is detached.
• Because attaches and detaches related to Autopath processing can occur quickly, this message may occur as devices are being moved between systems during Autopath processing.

Action:

Issue an MI DISPLAY or a CP QUERY command to determine the status of the device and the reason that the ATTACH/DETACH request failed.
