Status cannot be determined state | IBM DS8000 specs

Action

Ensure that a configured logical volume exists, and then resubmit the task. If the problem persists, contact IBM technical support for assistance.

CMUN03021E SOURCE Copy Services operation failure: device status cannot be determined

Explanation

A logical volume in the specification is either:

vUnconfigured

vFlagged for service

vIn the status cannot be determined state

vThe wrong type

Action

Make the volume or underlying device available, or specify another volume, and then resubmit the task.

CMUN03022E SOURCE Copy Services operation failure: source is destination

Explanation

The source and destination ports for a path over FCP must be unique. No port can be used as both source and destination.

Action

Specify two distinct ports, and then resubmit the task.

CMUN03023E SOURCE Copy Services operation failure: ESCON - FCP collision

Explanation

An attempt is being made to establish ESCON paths between two control units with FCP paths that already exist between the control units, or an attempt is being made to establish FCP paths between two control units with ESCON paths that already exist between the control units.

Action

Contact IBM technical support for assistance.
