We have a fully populated VNX array and would like to increase the storage capacity by only replacing the hard disks ( 5 x 300GB with 5 x 2TB).
The 5 current disks are in one pool and this pool does not contain any other disk. The LUNs of this pool can be migrated to another pool.
The disk replacement wizard only works on faulty disks.
The question is what are the steps to replace the 5 low capacity disks with higher capacity after emptying all the LUNS on it.
Your support is highly appreciated.
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.
...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?
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)
