vSphere MSCS Setup Checklist 6
When you set up MSCS on ESXi, see the checklists to configure your environment according to the
requirements. You can also use the checklists to verify that your setup meets the requirements if you
need technical support.
Requirements for Clustered Disks
Each type of clustered disk has its own requirements, depending on whether it is in a single-host cluster
or multihost cluster.
Table 6‑1. Requirements for Clustered Disks
Component Single-Host Clustering Multihost Clustering
Clustered virtual disk (.vmdk) SCSI bus sharing mode must be set to
virtual.
Not supported.
Clustered disks, virtual compatibility
mode (non-pass-through RDM)
Device type must be set to virtual
compatibility mode.
SCSI bus sharing mode must be set to
virtual mode.
A single, shared RDM mapping file for
each clustered disk is required.
Device type must be set to virtual compatibility
mode for cluster across boxes, but not for standby
host clustering or cluster across boxes on
Windows Sever 2008.
SCSI bus sharing mode must be set to physical.
Requires a single, shared RDM mapping file for
each clustered disk.
See VMware knowledge base article
http://kb.vmware.com/kb/1016106 to mark the
device as perennially reserved on RDM LUNs
used for MSCS virtual machines.
This configuration is not supported on Windows
Server 2008 and higher. This is a valid
configuration only on Windows Server 2003.
Clustered disks, physical
compatibility mode (pass-through
RDM)
Not supported. Device type must be set to Physical compatibility
mode during hard disk creation.
SCSI bus sharing mode must be set to physical
(the default).
A single, shared RDM mapping file for each
clustered disk is required.
