Hi Ani

The commands looks fine with few small correction needed,
the newfs command should be run on raw device

newfs -F vxfs -o largefiles /dev/vemcC30/rlvol2

And do remember to add the corresponding entry in fstab.(Hope there is no clustering).

Hi,

For new LV creation on a new disk on a existing VG [vemcC30] (on a stand alone server):
--------------------------------------
pvcreate /dev/rdsk/new_disk
vgextend /dev/vemcC30 /dev/dsk/new_disk <<<< you have mentioned a different VG_name and only new disk needs to be extended into the VG
lvcreate -L 102400M -n lvol2 /dev/vemcC30 <<<< -r N is default behaviour
newfs -F vxfs -o largefiles /dev/vemcC30/rlvol2
mkdir /warp/warp/database17
mount /dev/vemcC30/lvol2 /warp/warp/database17 <<<< take care for full LV name
bdf
Edit /etc/fstab file
