Hi Vijay,

You can extend / filesystem but it is nor easy, create a bootable backup tape with ignite software and restore your system to larger filesystems.

Maybe you could move data from / filesystem to an other filesystem.

yes you can extend the / file system. The easiest way is using ignite-UX command make_tape_recovery.

Hi Vijay,
The best and safest way is to use IgniteUX.

1. Get Ignite UX installed (It's free) on your system if you don't have one.
2. Create backup of entire VG00 volume as

# make_recovery -ACv -d /dev/rmt/0m

You can have your Tape device name if it is not 0m and then it will create a bootable tape.
3.Shutdown the system, replace disk if you are planning to do so and proceed with booting the system thr' tape.
4. While restoring it, it will prompt you to alter the Filesystem sizes if you wish to.

Hope this helps.
All the best.

Hi,

As the / as to be contigous, it is not so easy to extend it. The best way, is to do a backup by ignite an then restore your systeme with a file system resizing (advanced option in the ignite restore)

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

when this is complete reboot the system. Interrupt the boot process by rpessing any key in the first ten seconds. type "SEA" to list bootable devices they will be list P0 , P1, P2 ...

not type

bo PX where X represents the tape drive

interrupt with IPL (Y/N) N

the system will start to boot from the tape then ask if you wish to interact with Ignite, at this stage interact and specify new filestystem size for root then let restore continue.

on completion you should have an identical system with an enlarged root filesystem

The make_recovery command was used with the older versions of Ignite. Download the newest and use the make_tape_recovery command instead:

ignite is best way to go...

however, you do have an option....

root is usually lvol3 or lvol4 and need to be contiguous - you could "move" whatever is in lvol4 or lvol5 to a new lvol...then remove lvol4 or lvol5, then increase your root filesystem.
