Customer wants to swap drives in VNX5300
I have a customer in a dark site. VNX5300 with all 125 slots filled, all drives allocated to pools. No FAST VP or Fast Cache. He wants to try and get more space by pulling out 600GB SAS drives and putting in SATA drives. As it is in a pool not sure how he migrate data off disks prior to removing them from the pool. Any procedure or documentation on something like this?

You can't remove any disks from a FAST Pool. The only way to do this is to create a new pool on the same array and migrate all LUNs to the new pool, then blow away the original pool. Very inflexible. I've been asking EMC every chance I get to add a feature to evacuate a private raid group in order to remove disks from a pool.

Add a new DAE with disks, create a new Pool and migrate the LUNs...

That VNX is maxed out with 125 drives. I suppose they could do an upgrade to a 5500....

Hi Ben. Thanks for the rapid response. The environment does not use FAST cache or FAST VP. It is using pools so I suspect the result is the same, virtualized storage.

yes, thin pool, does not have to be using FAST or FAST Cache. Propose customer and upgrade in place to VNX5500 or loan them another VNX, migrate data using SANCopy, destroy pool, rip out old drives, buy new drives build new pool and migrate back. Sounds like a lot of work.
