Table 6‑1. Requirements for Clustered Disks (Continued)
Component Single-Host Clustering Multihost Clustering
Clustered disks, physical
compatibility mode (Shared VVol
storage)
Not Supported. SCSI bus sharing mode must be set to physical.
All types All clustered nodes must use the same target ID (on the virtual SCSI adapter) for the same
clustered disk.
A separate virtual adapter must be used for clustered disks.
Other Requirements and Recommendations
The following table lists the components in your environment that have requirements for options or
settings.
Table 6‑2. Other Clustering Requirements and Recommendations
Component Requirement
Disk If you place the boot disk on a virtual disk, select Thick Provision during disk provisioning.
The only disks that you should not create with the Thick Provision option are RDM files (both physical
and virtual compatibility mode).
Windows Use:

Windows Server 2003 R2 SP1 (32 bit/64 bit)
n
Windows Server 2003 R2 SP2 (32 bit/64 bit)
n
Windows Server 2008 SP1 (32 bit/64 bit)
n
Windows Server 2008 SP2 (32 bit/64 bit)
n

n
Windows Server 2008 R2 SP1 (32 bit/64 bit)
n
Windows Server 2012
n
Windows Server 2012 R2
For Windows Server 2003 SP1 and SP2, use only two cluster nodes.
For Windows Server 2008 SP2 and above, you can use up to five cluster nodes.
Disk I/O timeout is 60 seconds or more
(HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Disk\TimeOutValue).
Note If you recreate the cluster, this value might be reset to its default, so you must change it again.
The cluster service must restart automatically on failure (first, second, and subsequent times).
