hi;

if you dont have onlinejfs than

umount the corresponding filesystem
lvextend -L 200 /dev/cs04p2l5/archcs03
extendfs /dev/cs04p2l5/rarchcs03
mount the filesystem

hi,

if you have online jfs, after extending lvol with lvextend, do:

fsadm -F vxfs -b 204800000 /

Hi Yogesh,

For lvextend follow as follows,

#umount /mountpoint
# lvextend -L 204800 /dev/cs04p2l5/archcs03
# extendfs -F vxfs /dev/vg02/rarchcs03
#mount /dev/cs04p2l5/archcs03 /mountpoint

204800MB=200GB= (currentsize+newsize)

For Example,

#umount /dcs_appl01
# lvextend -L 25600 /dev/vg02/lvol1
# extendfs -F vxfs /dev/vg02/rlvol1
#mount /dev/vg02/lvol1 /dcs_appl01

Hi

to make sure that you have the OnlineJFS product installed you can have a look as

#swlist -l product | grep -i online

Also that the Product is validly Licensed, use

#vxlicense -p

If these are true then you can go for the extension of the FS as suggested in the earlier posts without getting the FS unmoounted and the applications accessing that FS runing.

If nit then you have to do that by unmounting, lvextend,extendfs and mount, and with that you shall have to stop the applications/ Databases stopped those are accessing this FS.
