Is it possible to provide ability to select local tier when creating a volume?
Applies to
ONTAP System Manager (OSM)
Answer
ONTAP System Manager 9.8
Process
- While creating SVM, volume, or LUN, there is no option to select an aggregate and where it should be placed
- The default behavior will be to place the aggregate automatically
- The same needs to be made available for SnapMirror destination
Workaround
- An alternative solution is to perform the volume create function from the ONTAP command line.
vol create -vserver <vserver> -volume <volume> -aggregate <aggregate> -size <size> -space-guarantee none
- Aggregates can be assigned to an SVM to restrict which aggregates System Manager can use to provision volumes.
CLI
vserver modify -vserver <vserver> -aggr-list <desired aggregate(s)>
UI
- Access ONTAP System Manager (new experience), click STORAGE > Storage VMs.
- Click Edit from the action menu next to the SVM name.
- Select Limit volume creation to preferred local tiers, and delete all the others aggregates other than the desired ones, then click Save.
- In STORAGE > Volumes, click "+ Add" to add new volume in the specified SVM.
ONTAP System Manager 9.9.1 and Newer
Process
When adding a volume in this release, select the "More Options" button, choose the "Custom" performance service level, and select the "Manual placement" checkbox to choose the desired local tier.
