Issue

Removing disks outside of the Deploy tool will result in unreclaimed capacity. Example:
 
 
  • Single node cluster deployed using 2TB (2x1TB disks):

(ONTAPdeploy) node storage disk show -cluster-name lgabor_cl1 -node-name lgabor_cl1-01
+----------------------+--------------+----------+-------------+------------+
| Name                 | Logical Name | Capacity | Pool        | ONTAP Name |
+----------------------+--------------+----------+-------------+------------+
| lgabor_cl1-01_4.vmdk | -            | 1 TB     | Datastore 2 | -          |
| lgabor_cl1-01_5.vmdk | -            | 1 TB     | Datastore 2 | -          |
+----------------------+--------------+----------+-------------+------------+

 
 
 
 
  • When the disk is not detached correctly, the changes won`t get properly updated in the Deploy utility and capacity will not be reclaimed:
