Mounting a Crashed drive 10.20

[Tom Riedman]

I am trying to mount a drive the won't boot on
10.20 C180

I ran the the vgimport on the /dev/dsk/ which create the lvol1 through 3 but I am sure that there was more than 3 volume on the drive. Now I can mount lvol1 to see my root info but lvol2 and 3 give errors about is corrupted need checking. On the imported drive it shows only 3 volumes, but I am sure that there
was more than that on the drive how and can I change the number of volumes.

More history if help.
When I try booting this drive it start to boot
but when it gets to about where it check to see if the disks need fsck then just reboots. I tried to to boot hpux -is but it also just reboots.
If more info is needed I will try.
Thanks for any Help.

Shalom,

Sometimes dead means dead.

You can try fsck on the /dev/vg00/lvol2 and /dev/vg00/lvol3 assuming you can boot the system. Try the Core OS CD.

Otherwise if fsck can not save it its gone.

Thanks for the reply but that didn't help with the question can I change the number of volumes within the group from 3 to like 9 or more

You can't really "change" the number of LVOLs on the disk. If vgimport is only seeing 3 LVs then that is all you are going to get.

Was this the only disk in the VG? Could there have been another disk in the VG that contained the rest of the LVs?

Things really don't sound promising here.

You could run 'fsck' on lvol3 and see if it will mount after that. There really isn't much point in trying to mount LVOL2 as that is your primary swap area, so no real data for you there.

It was the only disk in the box. I did this same thing couple years ago, someone then told me how I could create a VG than make make say 20 volumes within that new VG just make sure that I had more than needed. Then I was able to mount the drive. but I can find those notes on how I did this.

Thanks
