Solaris

I can't seem to get my host to see a 2540 array.

I have 3 arrays right now. (2) 2540's.. let's call them 2540A and 2540B and (1) 6140. 2540A and the 6140 are configured and mounted on the same linux host.

For the life of me, I cannot get the other problem-child 2540B to be recognized by the same linux host (x4150) as the other two arrays. No matter what, fdisk -l on the host doesn't list anything when 2540B is connected.

I've gone back to the start, disconnected all the cables, I've used the same PCI HBA, one controller, one fibre channel port, DAS, as the other arrays. I've re-setup the initiator, host, volumes, mappings, etc. Nothing. It's dead Jim. Argh.

I have another post on unix.com about comparing the performance of (2) 2540's vs (1) 6140. Let this post sever as an update. It's not going so well at the moment

I'd contact Sun, but I've gone down that route before only to be told by several sun engineers "I've never done support for a TRY&BUY" followed by no response for days.

Thanks for any help.

do you have CAM installed and configured the 2540B? is the latest baseline installed?

Hi,

Thanks for your reply.

Yes and Yes. Sorry I wasn't more clear in my original rant.

All the arrays are accesible via CAM and baselined. The 2540's are at firmware 06.70.54.10

I deleted and recreated everything from scratch again, pool, initiator, host, volume, mapping. I'm stuck.

I checked the licensing, it's ok too. Feature: Storage Domains, Enabled: True, Quantity Licensed: 2, Quantity in Use 1

There are no alams.

CAM reports the FC port link it UP too.

I'm staying calm and resisting the urge to throw it off the roof.

Thanks again

Well, I seem to be making :some: kind of progress.

I can get the 6140 and any ONE of the 2540's online. Not both of them. How odd. 6140 + 2540A, fine both arrays are present. 6140 + 2540B, fine both arrays are present. 2540A + 2540B - 6140, No only 2540B shows now. I'm so confused.

So as the problem stands now, I can get the host to recognize either one of the 2540's and the 6140, but not both 2540's simultaneously.

-puzzled-

there is a newer baseline available. but i don't think this is your problem. my problem is that i need solaris for troubleshooting... i don't know the commands in linux that would give me the infos that i need...
do you use some kind of LUN security (with WWNs)?

how do you attach all 3 storages to the host? how many HBAs do you use? SAN/DAS?

It seems I figured out my problem. It turned out that I'm a moron :-) While troubleshooting a dead fibre cable I inadvertently moved a cable from one HBA to another thereby invalidating one of the cam initiators. Check your cabling, redo your intiators. doh. Thanks for your replies.
