WSFC RDMs perennially reserved

[WuGeDe]

Hello
Should I set all RDMs in a cluster to perennially reserved or only the WSFC RDMs?
We always flagged only the WSFC RDMs.

From what I understand, it's only for RDMs that are used for guest clusters.
KB https://kb.vmware.com/s/article/1016106 explains this.

@a_p_ 
Yes. That is what I know.
WSFC RDMs should be flagged perennially reserved all other RDMs not.
But I am not shure about it.

The "Cause" section within the KB article actually explains it.

~snip~
This issue occurs when a cluster is running virtual machines participating in an MSCS/WSFC using shared RDMs and SCSI Reservations across hosts, and a virtual machine on another host is the active cluster node holding a SCSI Reservation.
