You can't remove drives from one pool and add it to another pool. You have to move that data from the block pool somewhere else, delete that pool and expand the second pool with unused drives.

Thank you sir.. this is my temo solution.. but

Can you provide any documentation of steps to relocate block data and then destroy it and add to File pool..

As dynamox said, you can do that. A pool can be shared for File and Block

Yes you can

Thanks for the quick reply Ernes..

Can i create a LUN/File pool from the Block pool and use it for NFS (By creating vocume then Pool for file and then NFS)???

Use LUN Migration on the VNX to move the block LUNs from one pool to another pool. Right-click on the LUN and select migrate. It's all online and doesn't cause disruptions; the host doesn't know that the migration is occuring.

Once you migrate all the LUNs on that pool you will be able to destroy that pool and the drives will become unused. At that point you can expand the second pool by select the unused drives.

Thank you guys... Awesome people here...

Its really helpful
