I have a cluster running on HPUX 11.23. I want to move one of the packages into a different cluster running on HPUX 11.31 - I have done this before, but I can't remember how I got the vg for the disks from the 11.23 server imported to the 11.31 server -
Would I be able to do this just by doing the standard vgexport -p -m map.file vg on the 11.23 server and do the vgimport -N -m map.file vg disk on the 11.31 server?
Solved! Go to Solution.

SolutionYes, that should work.
The only thing that may trip you up is the file systems vxfs version. HP-UX 11.23 supports file system versions as early as version 3. HP-UX 11.31 only supports file systems as early as version 4.
To determine the file system version you use the command 'fstyp -v' and run it against the raw logical volume.
For example:
# fstyp -v /dev/vg00/rlvol7 vxfs version: 5 f_bsize: 8192 f_frsize: 8192 f_blocks: 462848 f_bfree: 226372 f_bavail: 226372 f_files: 34080 f_ffree: 1075170792 f_favail: 1075170792 f_fsid: 1073741831 f_basetype: vxfs f_namemax: 254 f_magic: a501fcf5 f_featurebits: 0 f_flag: 16 f_fsindex: 9 f_size: 462848
Notice the "version" line in the 2nd line of output above. In this case the filesystem is vxfs version 5.
In your case, as long as the version listed is 4 or higher, you should be OK.
Information on available vxfs versions is here:

Re: Importing a vg from 11.23 to 11.31
Thanks. Looks like my lvols are using version 6 so I think I should be okay.
