va7100 initial setup help

Timothy P. Jackson — Tue, 01 Apr 2014 06:15:28 GMT

Hello Everyone,

I have a va7100 that I lost a controller on and now after playing with it I believe that i have messed up the entire configuration. Could some one please tell me what steps need to be taken through the serial por command line to create the lun0 so that cvui can see it.

I have read a lot of posts and the only two things I have seen is that there must be a lun0 for HP-UX 11.11 to see it and the controller card meeds to be in "HP-UX" mode. Also the recommended size of lun0 should be 10Gig <I think>

I cannot find any manuals that step me through this so any help would be greatly appreciated!

Thanks

Tim

Wow, still an old VA?

I currently have no access to my old docs, but I know the user guide is still available on the web. Try hp.com, please.

EDITED

I think it was

armcfg -L 0 -a 10M -g 1

Thanks Torsten!

I believe that i need the array-id after that command but I am not sure what the array-id is. I know this is old stuff but any idea where i might find it?

Also i have been searching for a manual both on the internet and docs.hp.com and have found basically nothing to help on a new install of a va7100. At least none of the setup commands.

Thanks again for your help!!

If you are doing this from your HP-UX that the array is attached to, then the command 'armdiscover' should work.

For example:

# armdiscover
This could take several minutes ...
HP-A6218A           /dev/rscsi/c7t12d0 00DEH43226RS     dcudb03.rwp.com dcarray1
HP 73.4G-ST373453LC /dev/dsk/c3t0d0    3HW0F1VW00007401 dcudb03.rwp.com
HP 73.4G-ST373454LC /dev/dsk/c2t1d0    3KP07CPT00007535 dcudb03.rwp.com

The last 2 items are the local disk drives on the system. The first is the array, its serial number, the host it's attached to and the array alias/nickname. You can use either the serial number or the alias/nickname in the commands.

As far as the 'armcfg' command mentioned above you will need the serial number / nickname after the command if working from HP-UX.

You can also have a look at the man page for the commands for more info.

# man armcfg

Thanks Patrick!

I think I may have another issue with the array....

when I do a armdiscover, it only shows me internal drives..... ?

i remember you can try to run cvui.

Thanks Torsten and Patrick!

I have one controller that is out completely... doesn't even want to give me a fiber connect. So I am going to get this fixed before continuing, hopefully it is my problem.

When i do a cvui it only shows me internal drives <I think>. It definately does not show me an HP Storage Array only JBOD disk.

I did read some where that if you don't have the lun 0 that it can really mess things up. But with out it, I cant find the array-id.

Re: va7100 initial setup help

Torsten. — Tue, 01 Apr 2014 17:10:29 GMT

>> does not show me an HP Storage Array only JBOD

Could you show the initial cvui screen?

Sure it is a VA but not a DS2405?

Sorry Torsten, I ended up in a very long meeting....

Here is what I get when I open up cvui...

I know for sure this is a va7100 because at one point it was up and running <over a year ago>. It wasn't until I changed out one of the controllers that everything went bad.

Thanks again for your response!

Make sure the server is connected to the host port, NOT to the disk port.

Re: va7100 initial setup help

Timothy P. Jackson — Wed, 02 Apr 2014 14:40:15 GMT

Hi Torsten,

The controller cards on the va7100 only have one port. I think the va7400 has two ports. my controllers only have one and it says "host"

Thanks for all the help!

Tim

Re: va7100 initial setup help

Torsten. — Wed, 02 Apr 2014 14:57:31 GMT

OK, the smallest VA (7100) doesn't have disk ports.
Did you try to connect to serial port and run the "armcfg" command?

Re: va7100 initial setup help

Timothy P. Jackson — Wed, 02 Apr 2014 15:02:10 GMT

tried to connect but from a laptop and the doesn't want to work. I am going to run over to our warehouse and dig out the old serial console. I know that it will connect with out a problem.

I will let you know when I have found it and have it connected.

Thanks!

Tim

Re: va7100 initial setup help

Torsten. — Fri, 04 Apr 2014 12:47:37 GMT

From the serial console do:

Ready> cfg -L 0 -a 10240k -g 1
Lun:0

Capacity:10240k

Redundancy Group: 1

Ready > dsp -L

LUN 0:

Capacity: 10.0 MB

Number of Snapshots: 0

RGID: 1

Thanks Torsten!

I got a little side tracted... We have Auditors in house this week and they are keeping me busy with stupid stuff.
