SCSI on DL360 and Linux OS

Hi all
Is could be possible to see the state of the SCSI disk on DL360 with RedHat AS 2.1?

Are you using a Smart Array?
If not try to check in the files given by
ls /proc/scsi/

and find out infos you need.

Peace, R.

Yes, I'm using SmartArray 5i.

ls -ls /proc/scsi
total 0
0 -r--r--r-- 1 root root 0 Apr 26 16:36 scsi

My problem is: I saw one disk in fault (confirmed by red led) ...Is there any way for the OS to get this foult information?

Thanks
Alessio

Ciao Alessio,
to stat info read files in /proc/driver/cciss/ .

to correct these problems you ought take a look at
www.hp.com/linux and download the correct Proliant Support Pack for your operating system. Install al the driver reading carefully the docs (a got some scratch infos, if you like, but I haven't time to set it up for you :_( )
Whit PSP you'll be able to change a drive 'on the fly' and edit arrays and so on while server is running.

Let Me Know.

Pax, R.

I agree with Roberto about the need for the utilities provided by HP.

The '/proc/drivers/ccis/cciss*' files give the configuration of the containers, not the state they are in.

I just walked over to a 'cciss' based server here and yanked a disk. Not a peep out of it. No logging, no beeping, no nothing.. woo.. munch-un-good.

Fired up the HP utility set (hpasm etc.), and boom.. There's a log entry! 4 of 'em actually!

All software for the DL360 class of machine is there. You will probalby want the package called "ProLiant Support Pack for Red Hat Enterprise Linux 2.1" (first link).

Thank very much, I have installed the PSP, but How can I utilize that? Which is the correct sintax?

Regards

Alessio

I think you should read _carefully_ the documentation to avoid PSP mess the system. Scripts are enough good but maybe you want to tue your machine in a different way.
If installation was ok you should reach the Managers at
https://localhost:2381
but please, read docs because a lot of things depends on how you have configured it.
To manage disks you must install the array configuration utility xe (acuxe) together with the cciss module for your kernel provided with PSP.

It a bit of work ;-) I spent more than a day to understand what it does exactly to the system and more than a week to learn all the matters regarding my servers about it. I suggest you to read a nice .pdf which explains almost all 'console configs' and troubleshoots. And I've no time to explain everything via web.

Maybe I can send the termin output of instllation on RH8

'hplog -v' is your friend. Anything that doesn't say 'repaired' is not your friend.

Have fun.
