Greetings Helen, hope this message finds you well.

Just for the sake of clarity, I'm copy pasting the patch description of the problem to share more context: Payload response change from REST means that the Device Label no longer exists in the format expected and causes an IndexError exception. This is the case in PowerMaxOS 5978.711 and later.

Do you mind sharing more detailed information so all the cinder team could understand:
- steps to reproduce this problem.
- cinder version
- The error is from c-vol ? Please share the full log output.

Thanks in advance, Sofia
