multipath help

All,

Here is my issue... I have 6 LUNs fo 400GB each assigned in the following order

LUN1 --> CTRLA

LUN2 --> CTRLB

LUN3 --> CTRLA

LUN4 --> CTRLB

LUN5 --> CTRLA

LUN6 --> CTRLB

On the array side, all are showing on CTRLB. Below is the mpath output and I need to figure out how to set each correctly so that 3 LUNs go to hba1 and 3 LUNs go to hba2.

From below output, you have your LUNs separated to each controller, but they are the reverse of what you intended. The mapth output contradicts what you have from your array. You are also using MRU, so I'm not sure if there were some kind of controller failover, but according to mpath, you are going out different paths on the ESX side.

Lun 1: Active on CtrlB

Lun 2: Active on CtrlA

Lun 3: Active on CtrlB

Lun 4: Active on CtrlA

Lun 5: Active on CtrlB

Lun 6: Active on CtrlA
