mounting a data disk on a new build system

[Paula J Frazer-Campbell]

Hi
I removed a disk using sam from my system before doing and rm -r * at root to clean a corrupt universe install (long story).

I have now reinstalled HP-UX 11 on the system and wish to bring this disk back on line without damaging the data on it.

Best method for doing this please.

Hi,

Is it an LVM disk? If not LVM and it had a filessyetm then it should be easy to reinstate.

mkdir /mymount
mount /dev/dsk/c?t?d? /mymount

edit /etc/fstab/to make it permanent.

I somehow think I may have missed your real problem though.

Cheers, Trevor

If you are using lvm, then did you do vgexport ?

Thanks,

Hi
No like a fool I did not vgexport it, I let sam do it.

Now at 23:10 after a long day my brain has gone and I just cannot think how to bring it back on line.

Any ideas greatfully received.

It is a lvm disk :-
Error on mount is:-

mount /dev/dsk/c5t6d0 /anite
/dev/dsk/c5t6d0: unrecognized file system

Try this...

mkdir /dev/vgpray
mknod /dev/vgpray/group c 64 0x010000

(this assumes that you currently only have one volume group configured. If you have more, then make the 0x01 to one greater than the number of VG's you currently have.)

vgimport /dev/vgpray /dev/dsk/c?t?d?

Then check /dev/vgpray to see if any LVs are there. If so then ..woohoo!.

Activate the volume group:

vgchange -a y /dev/vgpray

Then try to mount the lvol(s)

mkdir /lvol1
mount /dev/vg00/lvol1 /lvol1

Repeat for others if there are any.

Hi!
I got similar problem:
I got 2 identical disks! 18 GB each
On first disk is hp-ux 11.11 (/dev/dsk/c2t5d0) and on second is 11.00 (/dev/dsk/c2t6d0).

When i tried to mount disk device i got:
#mount /dev/dsk/c2t5d0 /hp1111
/dev/dsk/c2t5d0: unrecognized file system

Than i was tried with Trevor Dyson advice and i got it right, but still i cannot mount /dev/vgpray/lvol3 !!! I got following error:
# mount /dev/vgpray/lvol3 /hp1111
mount - unrecognized vxfs version number

Please help me!

How can i "read" what is in /dev/vgpray/lvol3

Sergej,

You should really start a new thread....not piggy back on this one.

Anyways, you can NOT mount a 11.11 file system created with defaults on HP-UX 11.0...

The vxfs version is 4 in 11.i and 3 in 11.0...

If you really want to do this, then you need to (on the 11.i system) create your file systems like this:

mkfs -F vxfs -o largefiles -o version=3 /dev/vg20/rlvol19
