EVA Device Naming is wrong

[Andrew Scott_3]

I've read this thread:

I'm having the exact same problem on two new itaniums running 11.23.

Server A:
presented Lun 1 = /dev/c16t0d0
presented Lun 2 = /dev/c16t0d0

Server B:
presented Lun 1 = /dev/c10t0d1
presented Lun 2 = /dev/c10t0d0

I've managed to map the controller instance and get the devices on Server B up to c16, but it won't flip the disks around the right ways.

After reading the thread linked above, I:

moved /stand/ioconfig and /etc/ioconfig
rebooted in single-user
ran ioinit -c
rebooted to multi-user
presented LUNs
ran ioconfig
ran ioinit -f to bump the instance up to 16
run insf -e

All works except the luns are backwards. Sever B assigns presented lun 1 actual lun 1, and presented lun 2 actual lun 0.

I have even gone as far as grepping the config from sever A and using it in the ioinit -f on server B (they are identical hardware). Same result. I've tried adding the two luns 1 at a time, still brings them in backwards.

Any clues? How do I reorder individual LUNs?

Andrew,

Do you have secure path installed on your systems? If you do, what happens when your run from both systems;
# spmgr display

Do you see the disks above? Check the WWLUN_ID.

As far as trying to get the lun numbers to match on the EVA, that can be a very difficult task. The eva will assign luns in the order that the disks are presented to them.
