If you have OnlineJFS installed

swlist | grep -i jfs

The filesystems are not OnlineJFS. They are VxVM or HFS

The file system simply needs to be JFS. Online JFS is a software product that has to be purchased and installed on the machine. You can check with "swlist -l product |grep -i online". You should see something like this:

# swlist -l product |grep -i online
OnlineJFS B.11.11 Online features of the VxFS File System

It is important to use the -l product - for if your OnlineJFS was included in a bundled OE - then it won't show with just a swlist - use -l product:

swlist -l product |grep OnlineJFS

Also, check if it is enabled with:

/usr/sbin/vxlicense -p

Hello Mridul,

As Pete's reply Online jfs is a Hp's licenced
software for you to maintain FS online
so if you asked how to checked it was installed or not?
Then;

#swlist -l product|grep -i online
must return like;
OnlineJFS B.11.11 Online features of the VxFS File System

Also for to check the necessary drives included in kernel or not?
Then;
/usr/lbin/sysadm/system_prep -s /tmp/system.out;grep ^vx /tmp/system.out

must return like;
vxdmp_q4
vxfs
vxportal
vxvm_q4
vxvm
vxdmp

so this means online jfs software installed
in your system and you can use it

Good Luck & Happy New Year

Hi Mridul ,

1] Online JFS is the feature of vxfs filesytem , that enables to extend online.
To check if a system has Online JFS installed or not use :

# swlist -l product | grep -i online

It should show like this:
OnlineJFS B.11.11 Online features of the VxFS File System

or

# /usr/sbin/vxlicense -p

2] # fstyp -v /dev/vgname/lvoln can be use to determine the type of filesystem.

Hope this will help ,

Cheers,

Raj.
