To determine if the kernel currently running on a system is a JFS 3.3 kernel, you can run:

/sbin/fs/vxfs/subtype

The output should be 'vxfs3.3'.

hi,
Check that OnLineJFS features were enabled:

# /sbin/fs/vxfs3.3/vxenablef

vxenablef displays the licensed features enabled in the kernel. If
OnLineJFS features are enabled, it will print the following:

System is licensed for features
Full_VxFS HP_DMAPI

If it does not show that OnLineJFS features are enabled, do steps 6 and 7.

6. [Troubleshooting only] Run vxlicense to enable OnLineJFS:

/sbin/fs/vxfs3.3/vxlicense -c

Type in the 23-digit license key at the prompt.

7. [Troubleshooting only] Run vxenablef to complete enabling of OnLineJFS
features:

/sbin/fs/vxfs3.3/vxenablef -a

OnLineJFS features are usable without a reboot.

HP OnLineJFS is the advanced optional product for the VxFS File System. The
capabilities of HP OnLineJFS can be used to perform certain key administrative
tasks on mounted VxFS file systems; this allows users on the system to perform
their work uninterrupted.

These tasks include:

- Defragmenting a file system to regain performance.

- Resizing a file system.

- Creating a snapshot file system for backup purposes.

The optimization runs online on a mounted JFS Filesystem

You can try these command on your filesystem
1. To Report on Directory Fragmentation

# /usr/sbin/fsadm -D /[filesystem-name]

2. To Defragment Directory

Note: "-s" option shows the summary of the activity
"-v" option shows the result in verbose mode

# /usr/sbin/fsadm -F vxfs -d -s /[filesytem-name]

3. To Report on Extent Fragmentation

# /usr/sbin/fsadm -E /[filesystem-name]

4. To Defragment Extents

Note: "-s" option shows the summary of the activity
"-v" option shows the result in verbose mode

# /usr/sbin/fsadm -F vxfs -e -s /[filesytem-name]

You can also try extending a test file system online.
