Case 4: Two Volume Sets each Mapped to Channel 0&1

When a Volume Set is created and mapped to Channel 0&1 LUN 0, the

Volume Set is Active in Controller 1 Ports 0 and 1 (Host A and Host B

channels), and Standby in Controller 2.

When a second Volume Set is created and mapped to Channel 0&1 LUN

1, the Volume Set is Active in Controller 2 Ports 0 and 1 (Host A and

Host B channels), and Standby in Controller 1.

In this case, all 4 ports will be active when the host system does IO on the

2 LUNs. This mode is Load Balance.

Volume Channel/LUN Mapping Remarks

Volume Set #000 0&1 / 0

Channel 0&1 => Ports 0 and 1 /

LUN 0 => Controller 1

Volume Set #001 0&1 / 1

Channel 0&1 => Ports 0 and 1 /

LUN 1 => Controller 2

NOTE: All even number LUNs

assigned to Volume Sets will be Active in

Controller 1 and all odd number LUNs assigned to Volume Sets

will be Active in Controller 2

IMPORTANT: MPIO must be configured on the host system(s), in

order for redundant LUNs (two paths via Controller 1 and 2) to

appear as single LUNs.
