Thanks for your responses. Is growing the DS and adding an extent the same? -Rahul

Did you selected "Same format as the Source" during migration ? Cause if disks was thin at source and converted to thick on the destination, then you will need more space.

To give you some info-The initial size of the LUN was 950 GB. Now it has been expanded to 2048 GB from the SAN end.Is the limitation of ESXI4.0 of maximum LUN size of 2 TB-512Bytes acting up here?-Rahul
