HP-UX Reinstall

[cheesytime]

I had a box running HP-UX 11.31, that box had mapped a NetAPP LUN, that particular NetAPP lun was into vg01 and had a logical volume on it with lots of data.

That box was re installed with HP-UX 11.23 for a proyect, with ioscan I see the NetAPP lun (2 paths)

disk 3 0/2/1/0.11.8.0.0.0.0 sdisk CLAIMED DEVICE NETAPP LUN
/dev/dsk/c4t0d0 /dev/rdsk/c4t0d0
disk 4 0/6/1/0.10.8.0.0.0.0 sdisk CLAIMED DEVICE NETAPP LUN
/dev/dsk/c6t0d0 /dev/rdsk/c6t0d0

I would like to know how can I view the data on that NetAPP LUN again?

Do i need to create a VG (say vg01) and then create a LV inside vg01 and mount it and the data will be there?

Please advice

Hi,

So if your current machine is 11.23 then you need to perform the following steps.

Do you have a old map file? If not , then follow below steps

1. mkdir /dev/vg01
2. mknod /dev/vg01/group c 64 0x010000
3. vgimport /dev/vg01 /dev/dsk/c4t0d0 /dev/dsk/c6t0d0

If yes, then
1. mkdir /dev/vg01
2. mknod /dev/vg01/group c 64 0x010000
3. vgimport -m tmp/vg01.map /dev/vg01 /dev/dsk/c4t0d0 /dev/dsk/c6t0d0

done, tried to mount the lvol

# mount /dev/vg01/lvol1 /omni
UX:vxfs mount: ERROR: V-3-20013: unrecognized vxfs version number
UX:vxfs mount: ERROR: V-3-24996: Unable to get disk layout version

I get that error...

Hi ,

This is because the 11.31 machine is having the JFS layout version 7 and if you try to mount that on 11.23 , then it will give you this error as 11.23 doesnot support this JFS layout version?

Can you run fstyp -v /dev/vg01/lvolX ?

Or better, the version of vxfs that was installed on HP-UX 11.31, which could be vxfs 4.1 / vxfs 5.0 or vxfs 5.0.1 , is a higher version then the one that is now installed on HP-UX 11.23, which can be vxfs 3.5/ vxfs 4.1 / vxfs 5.0.

To see which version of the base-vxfs bundle is installed on the current HP-UX 11.23, execute "swlist".

Then crosscheck the disklayout version that you get with the previous response "fstyp output", with which vxfs version that supports this on HP-UX 11.23 and upgrade to that version and retry the mount.

Greetz,
