Reason:
CA MIA has detected that DDR is about to switch the TO and FROM UCBs for a tape SWAP.
Name of the job involved in the SWAP.
Device being swapped from.
Device being swapped to.
Action:
No action is necessary. This highlighted informational message is issued as part of normal CA MIA processing whenever CA MIA detects that DDR is switching the FROM and TO UCBs for a tape SWAP. At this point in the SWAP, DDR has chosen the TO device and CA MIA has serialized the SWAP cross-system. CA MIA automatically deletes this message as SWAP processing progresses, either when the MIM2209I message is issued at the end of the SWAP or when another MIM2207I message is issued if the SWAP recycles (a problem occurs with the TO device or tape and DDR tries to SWAP again).
Note: For more information on tape SWAP processing and diagnosing tape allocation delays, including those involving tape SWAPs, see the following sections/chapters in the CA MIA System Programmer Guide:
