error while Save_config

Azaru — Fri, 04 Jul 2008 06:56:40 GMT

Hi All,

I have configured the ignite server and added the client. Now trying to create network recovery archive from server. But while doing it the recovery fails. The roor is as follows.

Have you changed disk on this machine ?
Check your boot configuration with lvlnboot.
Try to recreate /etc/lvmtab as well.

/dev/dsk/c3t0d0s2

Either that disk doesn't physically exist and is incorrectly stated in your lvmtab.

Or you have an issue with your disk and the system can't see it.

You have to remedy that first.

If the physical disk exists it may be down or bad. So you have to get it up and running again and ensure it can be seen (and CLAIMED) in an ioscan.

If it doesn't physically exist then you have to clean up your lvmtab.

Hi,

It is in claimed state only.

See the ioscan result for disk.

disk 3 1/0/1/1/1.0.0 sdisk CLAIMED DEVICE COMPAQ BD14689BB9
/dev/dsk/c3t0d0 /dev/dsk/c3t0d0s2 /dev/rdsk/c3t0d0 /dev/rdsk/c3t0d0s2

Hi Azaru,

ok about ioscan but please post also

lvlnboot -v
strings /etc/lvmtab

That should clear the reason save_config is failing.

Best regards,
Fabio

Hi,

Please find the results of

lvlnboot -v and
strings /etc/lvmtab

Hi,

so lvlnboot -v is the reason why save_config is failing.
I would troubleshoot the problem in the following way:

- try to recreate lvmtab as suggested by the message itself:
mv /etc/lvmtab /etc/lvmtab.OLD
vgscan -v

- if that doesn't help then try
lvlnboot -R
to recover links for lvols on BDRA;

- if that doesn't help troubleshoot the health of the disk, check by diskinfo, try dd, check syslog.log for errors.

Also does vgdisplay -v vg00 shows /dev/dsk/c3t0d0s2 or is it just a message from lvlnboot? Is /dev/dsk/c0t1d0s2 a mirror disk?

HTH.

Best regards,
Fabio

The second disk seems to be a mirrored one. Did you replace the disk recently. Can you do like this:

mv /etc/lvmtab /etc/lvmtab.old
vgscan -v (to recreate the /etc/lvmtab)
strings /etc/lvmtab

rgds.

Jeeshan — Mon, 07 Jul 2008 10:36:19 GMT

execute the command

#vgdisplay -v vg00

Hi,

I have tried every steps that u have given here. Nothing is resolved my problem.
And the health of the disk is

misapp3:root-/>diskinfo /dev/rdsk/c3t1d0

And

misapp3:root-/>mv /etc/lvmtab /etc/lvmtab.old
misapp3:root-/>vgscan -v
Creating "/etc/lvmtab".
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00".

lvlnboot: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.

here the vgscan -v command is not creating the fresh lvmtab.

What do we can do? Please provide me a good conclusion.

Thanks

Hi,

I think there is confusion.

- First of all the boot device from save_config message doesn't correspond to HW path of ioscan that you posted:

From save_config:
* Boot device is: 0/0/1/1/0.1.0

From ioscan posted:
disk 3 1/0/1/1/1.0.0 sdisk CLAIMED DEVICE COMPAQ BD14689BB9
/dev/dsk/c3t0d0 /dev/dsk/c3t0d0s2 /dev/rdsk/c3t0d0 /dev/rdsk/c3t0d0s2
/dev/dsk/c3t0d0s1 /dev/dsk/c3t0d0s3 /dev/rdsk/c3t0d0s1 /dev/rdsk/c3t0d0s3
/dev/dsk/c3t1d0 /dev/rdsk/c3t1d0

- then who is /dev/dsk/c3t1d0? I wonder it is showed on ioscan output, I'd expect it is on another HW path. More about c3t1d0 from info posted so far:

from vgscan -v:
Physical Volume "/dev/dsk/c3t1d0" contains no LVM information

It sounds like no pvcreate was never issued on it, so why did you launch diskinfo on it?

I think you should first clear which disk you expect to be the boot disk, I would suppose /dev/dsk/c3t0d0s2 (on Itanium platform s2 is always the EFI partition/boot of vg00).
So when I suggest doing checks on boot disks I suggest doing diskinfo and

dd if=/dev/rdsk/c3t0d0s2 of=/dev/null

And after a while stop by CTRL+C, do you get an I/O error?

Also you didn't response about vgdisplay -v vg00 and messages in syslog.log about disk problems. However after moving lvmtab it doesn't make sense doing vgdisplay, if no disk was found no disk will be showed.

vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00".

This is a clear message that you should check the disks.

We would like to give you a good conclusion, but here it needs more troubleshooting.
It sounds like you could not reboot your system until the problem is not solved.

Best regards,
Fabio

Hi Issue has been resolved

The disk was misplaced actually. So i have replaced it to original place and tried the following

misapp3:root-/>mv /etc/lvmtab /etc/lvmtab.old
misapp3:root-/>vgscan -v
Creating "/etc/lvmtab".
vgscan: Couldn't access the list of physical volumes for volume group "/dev/vg00".
