Cause
A code change in VPLEX 6.2 P5 (and higher versions) resulted in the deprecation of the REST API command in use by AppSync for distributed VPLEX volumes.
/vplex/v2/clusters/cluster-1/virtual_volumes/
Note: Appsync service plans protecting VPLEX local volumes remain unaffected by this issue.
Resolution
ResolutionThe issue is resolved in AppSync 4.5 per page 2 of the AppSync 4.5 release notes where it states:
APPSYNC-3833 This fixes an issue where vplex api got broken and protection started failing.
