using this configuration. For remote replication

4 logical drives (each has 4 member drives; for better
performance, you can include drives from the expansion
enclosure)
LD0 mapped to CH0 AID and CH0 BID; LD assigned to
controller A
LD1 mapped to CH1 AID and CH1 BID; LD assigned to
controller A
LD2 mapped to CH2 AID and CH2 BID; LD assigned to
controller B
LD3 mapped to CH3 AID and CH3 BID; LD assigned to
controller B

NOTE
In the event of Single-Controller failure, a logical drive is accessed through the host
IDs managed by the alternate controller. Host IDs and port IPs do not fail-over to
the surviving controller. Therefore, the MPIO multipath driver is necessary for path
redundancy and controller failover.
