Proliant 2500 & Linux not seeing raid

Hi
I am trying to install Suse 7.2 Pro on my Proliant 2500 tower ,twin CPU P200 Pro with 750megs of ram and a SCSI array, it has 3x4.3 gig, but soon to be upgraded, disks.
When I try to install using Yast it says there are no recognisable disks or valid partitons, this doesn't make sense, I have installed scsi modules but it just errors, at no point does it offer me the option to partiton, it is so frustrating,
I bought it off Ebay just to learn Linux and can't even get installed,I managed to install a dodgy copy of XP no trouble all disks recognised ok so I know they are OK.
I have a copy of the compaq software smartstart ver 5.3 and the management 5.3 and a smartstart server profile diskette.
Can anyone please point out to me my silly mistake or point me to a link, I have runout of ideas and have blisters from inserting and removing CDs.

Re: Proliant 2500 & Linux not seeing raid

1st, what kind of array controller is it? 2nd, have you run the array config utility to setup a logical drive?

Hi
Sorry to sound lame but, can you explain how to interrogate the device to find out the type etc please??
And as you ask maybe I haven't actually assigned the raid array.
I am at work now and cannot check anything till tuesday. Rgds

I cannot understand how the MS 'product' installs instantly but the Suse cannot see the disks?

Re: Proliant 2500 & Linux not seeing raid

HELP!!
I am totally stuck now I can't see how to do this poxy job, I have explored every avenue available in the smartstart disk, do I need another disk to set up and assign the raid, i appear to be running the smart 2sl scsi controller, at what point are you supposed to set up the array??
Is the disk I am using too late a version do I need an older version?
I have managed to upgrade the hard disks now to 9 gigs (5 off) all in the front hotswap bay.

Please help I am geting desperate.

Re: Proliant 2500 & Linux not seeing raid

hi simon

1) if ss5.30 boots into the installation screen select "manual installation". this will automatically lead you to the ACU (array configuration screen). when asked for the OS answer "other".

after step 1 your disks should be set up properly and ss5.30 will install the system partition (this is a hidden partition which can be accessed by pressing F10 after the initial messages).

after reboot you should see: initializing smart controller .... 1 logical drive

2) if ss5.30 boots into the tools menu, first run system configuration. reboot. then run array configuration.

that should do the job.

if NOT, download the diagnostics diskette - do not run diagnostics, but INSPECT. save it to a file and send it to:

ernst.limbrunner@web.de

ps: i have been doing proliant trainings for 12 years now ...

I tried to follow your instructions, i tried to create the array config utility bit the versions on the smart disk only run from the smart disk, they do create copies on the floppies but then wont run from there.
I have installed the partition many times and have worked with it, but when it comes to set up the array it can't because the floppies are non bootable.
I found an older smart start cd V4.2, this had an older version of drive array config which was bootable but it said there were no drivers, it makes no sense to me I am a PC head not used to this, i can't see why i can't write files to the sys partition if I could maybe i could install drivers.

I tried to run the diagnostics but the version on my cd is in japanese, bootable yes, understandable....er no. I down loaded one off the website and this does not appear to run it needs an OS to run, it runs on this Pc but the server says incorrect media...

I am stumped, i just don't know what more I can do?

To summarise, I have smart start Cds 4.20 5.10 5.30.

what you said makes sense but is as though something is missing, is it possible to find a bootable copy of the array config utility?

Thanks in advance, thanks for taking the time to reply, if we keep talking through here you can earn points and maybe we can help some other poor soul.

Re: Proliant 2500 & Linux not seeing raid

I have made a discovery of some significance here, i out of desperation last night took the box to bits to reseat the 2SL SCSI controller card. There wasn't one.
So, have i been the victim of an Ebay rip off, or do i have a 2500 that is just different. The SCSI cabe goes to what is labelled inside the case as a SCSI controller but is this type capable of controlling the hot swap type devices that are fitted to my unit, the controller appears to be either on the CPU card or connected directly to it via a header card.
What do I do folks, can I sort it or is it back to Ebay?
Yours dejectedly

Re: Proliant 2500 & Linux not seeing raid

Simon,

Grab a smart 2/P from ebay and go from there. I have 2 2500s running linux and freeBSD using that card.

The only gotcha to watch out for is a memory detection issue which can be defeated using the following:
mem=exactmap mem=640k@0m mem=(x-1)m@1m

Replace x-1 with your total ram -1 meg, for example if you have 512 meg of ram the line would be
mem=exactmap mem=640k@0m mem=511m@1m

Re: Proliant 2500 & Linux not seeing raid

Righto
I have managed to find a scsi controller card on Ebay, it is a 2DH card, which I believe is compatible, I have inserted it and have the machine running now and it appears to spin the disks which is more than it has ever seems to have done, but it is saying stopped due to scsi cable error is this because I have to terminate the on boards controller? It doesn't appear to work but now I have an error.

Am I on the right track at last?

Re: Proliant 2500 & Linux not seeing raid

Further to my last posting, I have found a scsi terminator, it is a
Single Ended Active device, part number, 12-41768-03, this had to be jigged to fit, which involved taking the plastic casing off, I get an error saying SCSI array not configured which I expected but I am getting this cabling error (1702-SCSI Cable Error) when I connect my drives to my new 2DH controller, wether the terminator is connected to the onboard controller or not, have I got the wrong sort of terminator? Can anyone suggest a part or part type, i am a bit stuck due to the layout, the terminator has to be very narrow with no lugs or will need to be on a cable, maybe this is what is required??

Re: Proliant 2500 & Linux not seeing raid

Have you configured the raid drive using the smartstart CD or the utilities in the system partition (Press F10)?

You need to create your array using one of those utilities before the software will see it.

Once the array is created the SuSe installer should see it. If it doesn't you may need to provide the following command at boot time to load the drivers: modprobe cpqarray

The problem I have now is that when I move the scsi cable to the new controller I get an error on the internal onboard controller saying cable error, I tried to put a terminator on it but it makes no apparent difference, I have since erased it all and started again, the 2DH controller is listed as the first controller but now it won't do anything,it just hangs at the scsi cable error as reported previously.
I can't see how to disable the onboard controller, there doesn't appear to be anything like a BIOS interface, I get errors when I try to do this in hardware config

Re: Proliant 2500 & Linux not seeing raid

I think I may have realised my problem, would I be right in thinking that the correct cabling for this would be for the original controller to stay connected, then another cable runs from the new controller to the SCSI backplane?
If so, cue sounds of nube banging his head on the desk!

Re: Proliant 2500 & Linux not seeing raid

Oh the saga drags on........

I have been looking at the proliant manual, Maintenance and Service 281834-001, on page 2-21 is says if connecting a expansion card it should be wired this way but, my machine does not have this sort of backplane on the drive enclosure, mine only has one scsi connector, so I managed to borrow a scsi cable for an alpha machine 17-04867-01, this has an extra scsi connector on it, I have managed to configure the array now but it says there are errors and the disks fail the post test, two fail at a time and it is never the same two.
I am stuck!
The 2DH error is 1777 it says wide transfer failed check the cables, the way I have it configured is the original controller, the 2DH controller and the backplane are all daisy chained, I no longer have the previously reported cable error now.
In the array config reporting it says although the config is wide is has only negotiated a narrow transfer, is this maybe because the disks have information on them from their previous lives?
Cheers
