Case 1: One Volume Set Mapped to Channel 0 LUN 0

When one Volume Set is created and mapped to Channel 0 LUN 0, the

Volume Set is Active in Controller 1 Port 0 (Host A channel), and

Standby in Controller 2.

Volume Channel/LUN Mapping Remarks

Volume Set #000 0 / 0

Channel 0 => Port 0 /

LUN 0 => Controller 1

Example: Channel Mapping in Fibre Host Channel

NOTE: When Volume Sets are created, the first Volume Set created (for

example: Volume Set #000) and assigned LUN 0 will be Active in

Controller 1 and Standby in Controller 2. The second Volume Set

created (for example: Volume Set #001) and assigned LUN 1 will

be Active in Controller 2 and Standby in Controller 1. The third

Volume Set assigned LUN 2 will be Active in Controller 1, and the

fourth Volume Set assigned LUN 3 will be Active in Controller 2.

In summary, 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.
