[BUG]: PowerStore Replication - Delete RG request hangs #928

Closed santhoshatdell closed 1 year ago

santhoshatdell commented 1 year ago

Bug Description

When the source RG is requested to be deleted on PowerStore, it doesn't finish and the test eventually times out.

Reason: Request to remove the associated protection policy before deleting the volume group doesn't remove the policy. Please see the logs. It was a regression introduced in gopowerstore module when there were volume group updates.

Workaround: User to manually disassociate the protection policy from the source side volume group when the RG deletion call hangs.

Logs

VolumeGroup PATCH request only has description in it. It used to send empty string for protectionPolicyId.
