CMMVC5923E: The FlashCopy mapping cannot be created, either because there are no online nodes in the I/O group or because there are unrecovered FlashCopy mappings in the I/O group.

Explanation

This error might be caused by a temporary loss of all of the nodes in the I/O group, which causes all of the FlashCopy mappings to be unusable.

User Response

Perform the following steps:

1. Ensure that at least one of the nodes in the I/O group of the mapping is online.
2. Fix all of the unfixed events in the event log.
3. Follow the fix procedures.

You might be required to delete and re-add ALL of the FlashCopy maps and Global and Metro Mirror relationships in the I/O group.

Resubmit the command.
