Adding Secondary Harddrive in HPUX that already has data

[Curt Donaldson]

So here is the problem. I have a HP C3700 with 2 disks in it. The bootable disk and the data disk. The bootable disk totally died on me this week. my delema is how can I can the data off of the secondary disk. I have a spare disk that I have booted the machine up with but the secondary disk (data disk) is unused in SAM?? How can I mount it

Thanks

# mkdir /dev/vgXX
# mknod /dev/vgXX/group c 64 0xYY0000
# vgimport vgXX /dev/dsk/cXtYdZ

If you need more of an explanation please let me know. But the disk in the vgimport command should be the device file for the secondary disk. It should read the lvm info from the disk and create your lvol files. Then you can mount them.

Shalom,

You don't mount a disk, you mount a logical volume as a filesystem.

You may be able to vgimport the disk into a volume group if the second disk was in its own volume group.

More likely you will need to use dd to read all the data off that disk into a tape or NFS share.

Then you'll at least have the data.

I'm hoping that the second disk was in a separate VG from your bootable disk. If so, then it should be a relatively simple matter to vgimport it:

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport -s /dev/vg01
- or -
vgimport /dev/vg01 /dev/dsk/c0t1d0

Ok thanks for your help so far, this is what I have one. First I am guessing it was setup as a seperate VG but I am not sure as I did not build this machine

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport /dev/vg01 /dev/dsk/c0t1d0

I get this back

vgimport: Physcal volume "/dev/dsk/c0t1d0" is not a block special file

any ideas??

Thanks

Is that even the device file for the second drive? run

# ioscan -funC disk

and double check. You may need to run

# insf -e

to create the device file.

I may have closed this to fast, I ended up importing the VG whiched imported the lvol's but they are unused. How can I get these mounted. Sorry my UNIX administration is not extensive

# mkdir /some_dir
# mount /dev/vg01/lvolX /some_dir

Add lines to /etc/fstab to make them persistent . Unless you want to mount them again after a reboot or power failure.

I have installed the old drive I thought was totally crashed but it seem to at least be recognized, just can't boot from it. It seem like there are no VG on it or they have been totally corrupted.

Can someone tell me how to use the dd command to copy everything from this drive to a nfs mount

thanks
