Environment

VxRail on VCF 5.x

Cause

The cluster deletion workflow is looking for an SSO account with name like svc-<vxrail manager name>-<vcenter name> and when it fails to find it (for clusters that were deployed prior to VCF4.5) it gives the above error message.

Prior to VCF 4.5 the SSO account name for VxRail Manager was in the format vxrmgmt_<cluster name/alias>.

Resolution

Contact GSS to assist with skipping this specific workflow.
