disk can't mounted after kernel upgraded, HPUX 11.31

[Weixing.Sun]

Hi expert,

I'm using a HPUX 11.31 , but after installed a new kernel, some disks on the system are not able to mounted.
Please help to give me a comments or workaround

the file system is vxfs version 7:
#run in old kernel
# fstyp -v /dev/dsk/c0t8d0
vxfs
version: 7
f_bsize: 8192
f_frsize: 1024
f_blocks: 71687369
f_bfree: 11014730
f_bavail: 10326310
f_files: 2962576
f_ffree: 2753680
f_favail: 2753680
f_fsid: 520126464
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 16
f_fsindex: 9
f_size: 71687369

# run in the new kernel
# fstyp -v /dev/dsk/c0t8d0
unknown_fstyp (no matches)

Thanks a lot

Additional info:

# mount -F vxfs /dev/dsk/c0t8d0 /extra
vxfs mount: V-3-20013: unrecognized vxfs version number
vxfs mount: V-3-24996: Unable to get disk layout version

seems the kernel not support vxfs version 7, but is there any workaround ? as I really need to use the new kernel.

Thanks

"after installed new kernel" ...
Could you explain a bit what you have done ?
My first guess : You are now running an older VxFS version (4.x perhaps ?) which doesn't support file layout 7?
Solution : Install a newer VxFS version (5.x) including latest patches.

Hi Wim

Thanks for your comments,
I have several disks with vxfs v7 on the system before, and currently the new kernel cannot identify the disks ,

the vxfs bundle of the old kernel is:

# swlist |grep -i vx
Base-VXFS B.11.31 Base VxFS File System 4.1 Bundle for HP-UX
Base-VxFS-50 B.05.00.02 Veritas File System Bundle 5.0 for HP-UX

and the bundle of new kernel:

So I think I need to install the compatible bundle of the veritas vxfs fs package.

Thanks a lot

the new kernel:

# swlist |grep -i vx
Base-VXFS B.11.31 Base VxFS File System 4.1 Bundle for HP-UX
Base-VxFS-50 B.05.00.02 Veritas File System Bundle 5.0 for HP-UX

there maybe some compatible issues with the old bundle and the new kernel I think

I have the same bundles on my system, and I can acess filesystem layout version 7 without issue.

Are you up-to-date on VxFS patches ? Maybe version 7 starts from a specific patch, but I can't find any documentation about that.
