No, you do it this way:

Hitachi LUNS = 0 1 2 3 4

Dual VIOS redundantly connected to HITACHI sees LUNS 0 1 2 3 4
(important that the hdisks be configured as the manual says
for Dual Vios, otherwise failover and load balancing fail due
to LUN lock).

Dual VIOS present the same disks to each partition via vSCSI
adapters.

IBM i sees both adapters and sees the 2 paths to each disk.

That's how i have it set up on a client, and that was how i
read the manual, but let's wait for Sue or the Dr to be sure.
Also, i'm not sure why they say IBM i 7.1, last i read it was
IBM i 6.1.1 or later.


Yes, this is the way it is done. Each VIOS server sees the same
set of LUNs using reserve_policy=no_reserve so neither places a
lock on the LUN.

Why Hitachi is saying 7.1 as the earliest release they support,
I haven't any ideas except perhaps it was simply the level they
chose to test with.
