NOTE: If you are running W2K8 VM Cluster with RDM-shared LUNs, then individually change

these specific RDM LUNs from Round Robin policy to Fixed Path policy.

NOTE: HP recommends changing the ESX Scsi.ConflictRetries from its default value of 80 to a

value of 200 when connected to an HP 3PAR StoreServ Storage running HP 3PAR OS version

2.2.4 or prior. This change lengthens the time allowed for I/O retries due to ESX SCSI-2 reservation

conflicts on VMFS LUNs caused by delayed processing of SCSI-2 reservation commands on the

HP 3PAR StoreServ Storage, thereby helping to avoid VM I/O failure.

You can change this value using the VMware ESX VI/vSphere client: In the ESX host, select the

Configuration tab, select Advanced Settings for software, select Scsi, scroll to Scsi.ConflictRetries,

and change the value in the field. Click OK to complete the change. A reboot is not required for

the change to take effect.
