pvcreate problem on 10.20

Brian Harris — Fri, 07 Jul 2006 10:38:23 GMT

I have added some 4 gig wide scisi df drives onto this system on a newly installed scsi controller, the drives come up as claimed. and exist in /dev/rdsk. But when I issue a pvcreate -B /dev/rdsk/c3d0t0 command I get the following error:
pvcreate: Couldn't open phsyical volume "/dev/rdsk/c3t0d0":
No such device or address

I am running an hp 9000/800 Model G30 with old OS 10.20. SAM does not recognize these drives but ioscan does and shows them as claimed, so I was trying to manually setup disk when I got this message.
Do to age of system customer is not comfortable trying to upgrade to 11 since they have no support and if have problems company would be shut down. I did look at get a patch for 10.20 to SAM /hp-ux_patches/s700_800/10.X/PHCO_22268. But I can not find a way to actually download this patch or if it still even exist somewhere on HP

So I am looking for suggestions on how to proceed.
Thanks,

If you really typed

pvcreate -B /dev/rdsk/c3d0t0

then you mixed up "t" and "d".

Make sure you have no SCSI ID conflict!
If the device is CLAIMED in ioscan, you should be able to do commands like diskinfo and even pvcreate.

check there is a hardware path asscoiated with this disk, use
lssf /dev/rdsk/c3t0d0
and/or
ioscan -funCdisk

then try using dd to confirm it can be read from, or written to:

read:
dd if=/dev/rdsk/c3t0d0 of=/dev/null bs=10k count=100

If that works, try a write
dd if=/stand/vmunix of=/dev/rdsk/c3t0d0 bs=10k
try this on all the new drives.
If these fail, there is something basic wrong

Yes in message had type,but in acutla command I did do c3t0d0.
but neither diskinfo or pvcreate seem to work. Below is result of ioscan

This disk is on 16.0.0 which is part of new SCSI controler that I just installed in hardware so there should not be any conflicts

# pvcreate -Bf /dev/rdsk/c3t0d0
pvcreate: Couldn't open physical volume "/dev/rdsk/c3t0d0":
No such device or address
# diskinfo -v /dev/rdsk/c3t0d0
diskinfo: can't open /dev/rdsk/c3t0d0: No such device or address

I tried the lssf command which came back with valid information, but the dd commands failed in same way as pvcreate and diskinfo

# dd if=/dev/rdsk/c3t0d0 of=/dev/null bs=10k count=100
/dev/rdsk/c3t0d0: No such device or address
dd: cannot open /dev/rdsk/c3t0d0

Re: pvcreate problem on 10.20

This sounds like a firmware or connectivity issue then.
You need to look at the firmware that is required on the discs, also what card is being used etc.
If I recasll, the G30 uses an HP-PB FastWide card to connect DF drives.
Check the cables and drives.
Are these drives HP? If not there could be an issue due to non supported firmware, I have seen this on HP-UX 10.20

Re: pvcreate problem on 10.20

Brian Harris — Fri, 07 Jul 2006 11:33:11 GMT

I am not sure what/how to check firmware
OS Identification: B.10.20 C info
All hardware is HP.
HP-PB FWD SCSI host adapter 28696A
HP Disk: 4.3gb Fwd Lp Disk Module A3647A
The disk are installed in an HP Hass deskside subsystem A3311A.
The only thing I can think of is if I am missing a driver, but If so I am not sure which one, I included scsi3, hpfl1. I did not include hpib1 maybe this one is needed, I didn't do it because ioscan showed that it worked

Re: pvcreate problem on 10.20

Torsten. — Fri, 07 Jul 2006 12:02:52 GMT

Most likely not a driver problem, because the devices are claimed. Can you access the other disks on that bus?

Re: pvcreate problem on 10.20

Victor Fridyev — Fri, 07 Jul 2006 12:06:50 GMT

Hi Brian

If the disk is used, sometimes pvcreate -f (force) parameter.
BTW, did you reboot the computer after the disks connection ? You even may have to swich off, switch on computer.

HTH

Re: pvcreate problem on 10.20

Brian Harris — Fri, 07 Jul 2006 12:14:49 GMT

none of the other disk on system are accessiable. I did try using -f in pvcreate command. These disk are used, and supposedly worked before shipped to us according to our supplier. I don't know if I have to reformat these drives in some way?
I did do a power of reboot when I connected hardware, but after that I only did kernal install reboots, to try different drivers.

Re: pvcreate problem on 10.20

Victor Fridyev — Fri, 07 Jul 2006 12:18:08 GMT

Hi,

Do the disks answer to
#>diskinfo /dev/rdsk/XXXX ?

If you see a normal output, try to format the disks with mediainit

HTH

Re: pvcreate problem on 10.20

Torsten. — Fri, 07 Jul 2006 12:50:40 GMT

This sounds strange. The system can see the disks, because there is a claimed status and there are device files created.
I would check (and replace) the cables and terminators, remove all disks and insert only one at a time and try again.

Re: pvcreate problem on 10.20

melvyn burnard — Fri, 07 Jul 2006 12:53:29 GMT

hmm. weird

Sill;y question, is the cable a self terminating one? and if so do you have a separate terminator on th eJBOD?

Reduce the discs down so there is just one disc and try again.
If this works it is normally a cable/termintaion issue

Re: pvcreate problem on 10.20

Torsten. — Fri, 07 Jul 2006 13:05:25 GMT

For this test with only 1 disk use only one half off the HASS, e.g. connect the cable to the left half on the upper port and terminate on the lower.

Re: pvcreate problem on 10.20

Brian Harris — Fri, 07 Jul 2006 13:05:44 GMT

I have DF terminators on disk storage system, I am heading over to customer to change cables and try with 1 dirve at a time all dirves are HP hot swable drives.

OldSchool — Fri, 07 Jul 2006 15:44:33 GMT

Your ioscan shows the driver "disk3" has claimed these, and also shows them as floppies?

I believe the correct driver is either disk2 or stape, but I can't prove it.

Re: pvcreate problem on 10.20

Torsten. — Fri, 07 Jul 2006 16:24:50 GMT

@System Administrator:

The system is probably an old G- or H-Class which has a hardware path 52.x as internal single ended SCSI bus and hw-path 16.x as HP-PB (precision bus) slot for additional cards.

HW-path 16.x is always slot 4 according to the original precision architecture (aka PA from PA-RISC).

The driver and the device files are likely ok for this generation of systems. For sure it is not stape! Guess why there is "tape" in the name!

Brian, please keep us posted!

Re: pvcreate problem on 10.20

Brian Harris — Sun, 09 Jul 2006 20:12:40 GMT

Yes this is an old G server where 52 is internal scsi and 16 was for the added scsi controller that I am tring to use for disk.

I did go to customer and tried sveral different combination of disk and A and B side of HASS unit and always got same result as previously mentioned. I also tried a different SCSI controller on a duplicate machine and got same results.

In addition when I try to look ad disk in sam I get following message
SAM was unable to determine the disk drive model of the disk drive
attached to your system at hardware path 16.0.0. This device will be ignored. If this unit is a CD-ROM drive, check to see if there is any media (a CD-ROM disk) in the drive. If there currently is no media in the drive, you can correct this problem by inserting the desired media and choosing the "Refresh List" item from the "Options" menu.

I am wondering if problem is due to fact that disk being used came out after the last time O/S on system has been upgraded. I am very leary of tring to upgrade this system to 11.0 because if anything doesn't work I may not be able to get it to work in timely fasion, because their business model is 24/7 operation. I have been tring to find 10.2 bundled patches so that maybe one of the patches have info for disk. But I have not been able to find patches, HP only has patches for 11.0.

Does any one have any suggestions on getting 10.2 patches. Do you think I may be on correct tack

Thanks

I found PHCO_22268 only here

http://h20331.www2.hp.com/Hpsub/cache/285370-0-0-225-121.html

1. download 1020cfg_jun03.gz
2. use gunzip to uncompress the file
3. use tar xvf to extract all files
4. use swinstall and select PHCO_22268

Just recently, HP has removed all pre-11.00 patches from the ITRC patch finder page. That should tell your customer something very important -- the OS has been obsolete and out of support for several years. If it is working now, the customer should try to change anything, especially adding new products. It will be extremely difficult to get replacement parts and the new ones may simply not work.

Now the drives may work OK but it sounds like your customer did not properly patch their system. With their business totally dependent on this machine, I would STRONGLY recommend getting another G30 (or G40, G50, etc) and cloning it using Ignite/UX. Then add ALL the patches for 10.20, ideally from the Support Plus CD dated Dec 2001. Then add any others from the HP archive location:

ftp://ftp.itrc.hp.com/archived_patches/hp-ux_patches/10-800.html

Now test the cloned system to make sure it works OK (with the new disks and current applications) and switch to the new system at a later date. Note that this is still a bandaid since locating 'supported' hardware like tiny disks and old DDS-2 or DDS-3 tape drives will be increasingly difficult to locate.

With so much depending on this system, an immediate course change is needed to keep things operational. I would NOT recommend 11.00 but instead, get a small rp2405 or similar, which will run 11.11 just fine and will be 5 to 10 times faster than the G30. These 'older' boxes are quite inexpensive, require 1/4 the power and airconditioning and less than 1/5th the space. As with the above duplicate G30, you load and patch the system, then add the applications, test and fix anything that needs work.
