vxfs fsck: unrecognized vxfs version number

[Abbasi Tinwala]

Hello,
I am getting following error while fsck/mounting the volume.
vxfs fsck: unrecognized vxfs version number

Server1 :
HPUX 11.23
JFS3.5

Server2:
HPUX 11.11
JFS3.3

The source luns are assigned to Server1 from storage and the clone luns are assigned to Server2.
After performing the vgchid,vgimport,vgextend operation,i am getting error as mentioned.

Will updating JFS version to 3.5 solve the issue ?
Also could anyone provide the link to download JFS3.5 ?
Any help will be appreciated.
Thanks
Abbasi

You created the filesystems under 11.23 and are trying to use them under 11.11. That dog won't hunt. Turn the world around and create the filesystems under 11.11 and then both 11.11 and 11.23 can mount them. Vxfs is designed to be upwardly but not downwardly compatible.

Hi:

You undoubtedly have a VxFS version layout mismatch. The highest value suppported for 11.11 under JFS 3.3 or JFS 3.5 is four (4). Version-5 is supported only on 11.23 with JFS 3.5 or later so upgrading 11.11 to JFS 3.5 isn't going to help if the underlying filesystem layout is higher than four.
