Correct Answer:A,B,C.

Multipathing support

Multipathing to a boot LUN on active-passive arrays is not supported because the BIOS does not support multipathing and is unable to activate a standby path.

SAN considerations

If the array is not certified for a direct connect topology, the SAN connections must be through a switched topology. If the array is certified for the direct connect topology, the SAN connections can be made directly to the array. Boot from SAN is supported for both switched topology and direct connect topology.

A) If the array is not certified for a direct connect topology, the SAN connections must be through a switched topology. If the array is certified for the direct connect topology, the SAN connections can be made directly to the array. Boot from SAN is supported for both switched topology and direct connect topology.

B) Yes!
Each host must have access to its own boot LUN only, not the boot LUNs of other hosts. Use storage system software to make sure that the host accesses only the designated LUNs.

D) No: Multipathing to a boot LUN on active-passive arrays is not supported because the BIOS does not support multipathing and is unable to activate a standby path.
