Need more info.
What is behind of mount point ? What is FS type and where it reside ?

1. NFS. NFS server should do the work.
2. Partition. Hmmmm. Resize LUN, reboot into single, remove and rebuild partition, resize2fs (or suitable tool for other FS)
3. LVM. Probably you have spare place (check with pvs), then lvresize + resize2fs (or whatever).

See more hints: HOWTO LUNs on Linux using native tools
and: HOWTO align VMware Linux VMDK files

The server is attached to a SAN box and using ext3 FS.

So my question is what information i need to pass the storage team for allocating new luns?.

Try ask them to enlarge existing LUN.

Still have not enough info. EXT3 is good.
Where resides EXT3 ?
On partition ? On whole disk ? On LVM's LV ?
In last case, Do you have spare space in PV ?

Ext3 resides in the partition and is managing by Veritas volume manager.There is no space in pv.

Veritas VM can resize LV on-line.
Then ask enlarge LUN (if possible) from your storage team.

Resize LV using Veritas volume manager.
I am not sure about Veritas + ext3 integration,
would you use vxfs, then vxvm will resize FS for you too.
If this not happen, then resize2fs to finish your task.
