mount external boot disc for reading - urgent!

[Torsten.]

Why vg00?
You'll need a new vg for the new disk.
You can't import it to an existing vg.

Check also the directory /etc/lvmconf for unused entries. if there is vg00 is configured only, there have to be this files:

vg00.conf
vg00.conf.old

[V. Nyga]

The 735 has a HFS disk and a VxFS disk (very old configuration)
The j200 had a LVM boot disk

vgchange says at the end: volume group "/dev/vg00" couldn't be activated.

Could I have destroyed the LVM infos?

Which mount command could I try?

[V. Nyga]

Hi again,

there was no vg on the ws before:
/etc/fstab:
/dev/dsk/c2t6d0 / hfs defaults 0 1
/dev/dsk/c2t5d0 /disk2 vxfs rw,suid,delaylog,datainlog 0 1
/dev/dsk/c2t5d0 /disk2 swap end,pri=0 0 0
cadfek1:/opt/pro /opt/pro nfs rw,bg,hard 0 0

cross geraete verweis - cross device links message points to lvlnboot problems. Check lvlnboot -v. This should only show the original boot disk. Restore the information with

lvlnboot (see man page) and try again.

You have a non lvm structure on your disk. I haven't seen this since hp-ux 9. Of course, it's possible with later versions too.
What OS version is on that system?

[V. Nyga]

It's 10.20

so lvlnboot -v only shows my new vg, but as 'not activ'

Vo,

Check this doc.

rj - vgchgid only works for EMC discs.

vgimport -v /dev/vg01 says:

Import begins
volume(device?) cannot be read

[Robert-Jan Goossens_1]

Vo, can you see the disk in ioscan -fnCdisk ?

http://www5.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000079989760

[V. Nyga]

rj - yes I can see it.

In the dokument - I don't understand this lines:

To match the group of disks to a single volume group do the following:
FYI: 0x2008?4 is always the offset of the lvm data structure.

# echo 0x2008?4D|adb /dev/dsk/c0t0d4

Maybe too late today - I'll continue tomorrow

Thanks V.

[V. Nyga]

hmm - how to check if the disk is ok or not??

[Robert-Jan Goossens_1]

# dd if=/dev/rdsk/cxtydz of=/dev/null bs=512kb

Hi Volkmar ,

Try to check the disk if it is ok or not,
try reading the disk with dd as follows:

dd if=/dev/dsk/c0t0d4 of=/dev/null bs=1024

[Press Ctrl+c to stop ]

* and keep an eye on the LED of the disk, it should keep glowing.., If not the disk is having problem.

Cheers,
Raj.

dd works (rj - with k instead of kb)

so it seems like I damaged/formated the boot sector of the disk

It would have been better to select 'volume groups' in SAM instead of 'disks devices'

There's also the possibility to import vg's.

I tried to create a new logical volume (over the existing?) and this didn't work.

Thanks to all!

[V. Nyga]

Thanks - I believe all would have worked - I should have asked earlier :-(

I hope I can read an older backup tape of the ws.
