KNOWN ISSUE:
Workload support was dropped in ucode 5978. If a VMAX All Flash array is
upgraded to 5978 or greater and existing volume types leveraged workload
e.g. DSS, DSS_REP, OLTP and OLTP_REP, attaching and detaching will no
longer work and the volume type will be unusable. Refrain from upgrading
to ucode 5978 or greater on an All Flash until a fix is merged. Please
contact your Dell EMC VMAX customer support representative if in any
doubt.
