When you expand a pool LUN you will be prompted to enter the total NEW capacity you want the LUN to be expanded to, not the amount you want to increase it by.
So if your current LUN size is 500GB, and you want to expand it by a further 200GB, you will enter 700GB into the "New User Capacity:" box.

Damodar,
Please see the note below...this is mentioned in VNX2 white paper.
Expanding pool LUNs
Virtual Provisioning also simplifies storage management tasks by providing the ability
to expand pool LUNs with a few simple clicks. The underlying pools can also be
expanded by adding drives non-disruptively when additional physical storage space
is required. Using thin provisioning reduces the time and effort required to provision
additional storage, and avoids provisioning storage that may not be needed.
Note: LUNs that are assigned to VNX for File cannot be expanded. If additional
capacity is required on VNX for File, new LUNs should be created and assigned for
AVM to manage.
For a thick LUN, the pool must have enough storage for the LUN expansion to
succeed, whereas for a thin LUN the storage does not need to be available. It is
important to note that you cannot expand a pool LUN if it is part of a LUN-migration or
data protection operation such as MirrorView.
Regards,
Murthy Chilla
