ESX Boot from SAN

• ESX v3.x. RDMs are supported with v3, but not v2


• HBA should be plugged into the lowest PCI bus and slot number to help the drivers detect the HBA quickly.


• For Active/Passive arrays, the SP's WWN that is specified in the HBAs BIOS must be active. If not, no boot!!


• Ensure that boot LUNs are masked to only the ESX server that needs it.


• Must be in SAN switched fabric. Direct connect and FC arbitrated loop are not supported.


• For IBM eServer BladeCenter, IDE drives must be disabled on the blades.


• The HBA BIOS must designate the FC card as the boot controller.


• The FC card must be configured to initiate a primitive connection to the target boot
  LUN.

To set up BfS, see the SAN Config guide.
