Upgrading the VNX storage capacity by replacing the disk

hi mirzahabib,

Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility.  Questions written to the users' own "Discussions" space don't get the same amount of attention and questions can go unanswered for a long time.

You can do so by selecting "Move" under ACTIONS along the upper-right.  Then search for and select: "VNX Family Support Forum" which would be the most relevant for this question.

Hi Mirza,

You could;

• Migrate the LUNs to a different pool (which will remove original LUNs)
• Delete the pool
• Swap out the disks and recreate the pool, create LUNs and migrate them back

...BUT do you really want to create a RAID 5 pool with 2TB NL-SAS drives ? (non seq performance will be poor and rebuild times long)

Do you have any other options ? Which VNX do you have ?

Thanks for the response.

Right now the objective is to increase the capacity only and not to bring the same LUNs back as there is enough space in other pool.

The VNX is 5300 and is part of VBlock.

Do I have to follow the disk replacement wizard (which replaces failed disk only) or just physically swap the disks and the new disks will be sensed automatically by VNX?

Regards

there is no procedure or replace the drives unless it's faulty.

  you can just remove and insert the disks manually, it'll detect automatically.  (Make sure pool is deleted before doing it)
