This topic provides a checklist of special setup requirements for different storage systems and ESXi hosts.
|All storage systems||Write cache must be disabled if not battery backed.|
|Topology||No single failure should cause HBA and SP failover, especially with active-passive storage arrays.|
|EMC Symmetrix||Enable the SPC2 and SC3 settings. Contact EMC for the latest settings.|
|EMC Clariion||Set the EMC Clariion failover mode to 1 or 4. Contact EMC for details.|
|HP MSA||No specific requirements|
|HP EVA||For EVA3000/5000 firmware 4.001 and later, and EVA4000/6000/8000 firmware 5.031 and later, set the host type to

|HP StorageWorks (formerly LeftHand)||Make sure ARP Redirect is enabled on independent hardware iSCSI adapters.|
|ESXi Configuration||Set the following Advanced Settings for the ESXi host: Disk.UseLunReset to 1.
A multipathing policy of Most Recently Used must be set for all LUNs hosting clustered disks for active-passive arrays. A multipathing policy of Most Recently Used or Fixed may be set for LUNs on active-active arrays.
Allow ARP redirection if the storage system supports transparent failover.
