VMware Best Practices
Follow HP recommendation from the specific server booting from a SAN.
Enable and configure the adapter correctly, to allow it to access the boot LUN.
Each host must have access to its own boot LUN only and not others. Use storage system
software to ensure the host accesses only its designated LUNs.
Multipathing to a boot LUN on active-passive arrays is not supported because multipathing is
not supported by BIOS and is unable to activate a standby path.
SAN connections must be made through a switched topology if the array is not certified for
direct connect topology. If an array is certified for direct connect topology, SAN connections
can be made directly to the array.
NOTE: Boot from SAN is supported for both switched topology and direct connect topology
if these topologies are certified for the specific array.
See specific ESX/ESXi 3.x, 4.x, and 5.x installation documentation at http://
