pvcreate not working.

stevegray — Thu, 26 Apr 2007 05:29:40 GMT

I did a cold install of HP-UX11.31 on my rx8640-16 Integrity system.

vg00 is not mirrored. I am following appendix A in the "when good disks go bad".

When I did the pvcreate -B /dev/rdsk/c6t6d0s2 command it gave the follwing error:

pvcreate: Unable to query the I/O interface: System call error.

What does this mean??

Thanks
Steve

Hi,

to be consequently you should use the new devicenames, e.g.

/dev/disk/disk6_p2

for your operation.
Look it up:

ioscan -m dsf

Is the disk CLAIMED in ioscan?

Also check the the status with:

$ ioscan -P health -C disk

ioscan -m dsf shown my disk /dev/rdsk/disk5.

ioscan shows it is claimed.

The health shows:

Class I H/W Path health

disk 3 64000/0xfa00/0x0 online
disk 4 64000/0xfa00/0x1 online
disk 5 64000/0xfa00/0x4 online

I hope that you have created partition file then used idisk to create partition followed by insf -e.
If you have not executed insf -e then these device files won't get created.

I agree with Mridul, you should exactly follow the procedures, but I would use the new device names, like

/dev/disk/disk5
and
/dev/disk/disk5_p2

Re: pvcreate not working.

stevegray — Thu, 26 Apr 2007 05:55:10 GMT

The command I used was

insf -e -H 1/0/0/2/0.6.0

The next command was the pvcreate.

Re: pvcreate not working.

Torsten. — Thu, 26 Apr 2007 05:57:08 GMT

You probably missed the step

insf -eCdisk

because the devie files

/dev/disk/disk5_p1 _p2 and _p3 are missing

Is the number in the partition file the number of partitions on vg00?

The example said 3. I have 8 partitions.

Re: pvcreate not working.

Mridul Shrivastava — Thu, 26 Apr 2007 06:07:39 GMT

Partition file will look like following:
3
EFI 500MB
HPUX 100%
HPSP 400MB

so the first one for EFI , second one for OS and the third one for some maintenance utilities.

the 8 file ssytems u r talking about are part of OS.... which is different from the partitions we are talking about.

stevegray — Thu, 26 Apr 2007 06:35:31 GMT

Torsten was correct.

I did not run insf -Cdisk.

I did not see it in my directions.

I can now proceed.

Thanks for the help.
