Adding new disk to an Existing adp aggregate

Hello,

 

Recently we received a CDot cluster with 12 partitioned disks pre-installed from NetApp and we started using it and a week later we received 2 more SSDs which were not in the package earlier. 

 

Now we have layout like below

 

filer0300::> disk show
                     Usable           Disk    Container   Container
Disk                   Size Shelf Bay Type    Type        Name      Owner

Can we use the 3.49TB unpartitioned disk in the aggregate "aggr_single_file" or we can only use the partition 1.0.11 (1.68TB) in the aggregate expansion.

Would it mean that using 1.0.11 (partitioned space) would leave us with no spares in the Raidgrp?

Re: Adding new disk to an Existing adp aggregate

Any whole disk that is added to a raid group that contains partitioned disks will automatically be partitioned to match the rest. If you were to add the data partition on 1.0.11 we would still be able to use the whole disk at 1.0.13 as a spare. It would automatically be partitioned to replace any of the failed data partitions.
