find out JFS version

[CAS_2]

Hi

Both JFS and OnlineJFS are installed in my HP-UX 11.11 box, but I want to find out its version (3.3 or 3.5). The output of swlist command doesn't show that info.

# swlit -l product '*JFS'

# Initializing...
# Contacting target "node0"...

OnlineJFS B.11.11 Online features of the VxFS File System

Hi CAS,

You can use
# fstyp -v /dev/vgxx/lvolxx

Cheers,
Raj.

'fstyp -v' reports layout version, not software version. VxFS layouts in my box are '4'. According to docs and white paper, '4' is the default layout for both JFS 3.3 and JFS 3.5 in HP-UX 11.11.

I've seen the installed kernel patch (PHKL_28512), whose description is "Fix for POSIX_AIO in JFS3.3"... thus I believe JFS 3.3 is installed.

As shown in the post opening this thread, swlist commands just shows B.11.11 as version for "OnlineJFS" and JFS products. But in other HP-UX 11.11 boxes, swlist shows (B.11.11.03.03):

JFS B.11.11 The Base VxFS File System
OnlineJFS B.11.11.03.03 Online features of the VxFS File System

Perhaps it depends on the product number.

Cas,

This command shoul tell you the version of JFS that you are running,

what /stand/vmunix | grep libvxfs

Regards,

Jaime.
