Enabling Drive Security on a Post-Deployment StorageGRID SG6060 with FIPs Disks

I needed to enable drive security on some StorageGRID SG6060 storage nodes. The StorageGRID version is currently 11.9.0.6 and SANtricity is 11.70.5P1.

There is a good NetApp KB:

Enabling security encryption on a StorageGRID Appliance fails - NetApp Knowledge Base

And I am mostly using the text from there, with additions. And - for customer documentation purposes - I capture extra screenshots to make things more clear.

Solution: Post-Deployment

Note: You can only put one node per grid into maintenance mode at a time.

1. Put the StorageGRID storage node into maintenance mode (this will stop all IO operations to the Storage system).

From Grid Manager select Nodes -> Select appliance node -> Select Tasks tab -> Click Maintenance Mode -> Enter the provisioning passphrase, and click OK.

2. Disable SSD cache on StorageGRID-flash-cache.

In Storage > Pools & Volume Groups
Select the StorageGRID-flash-cache pool

From the More menu, select Suspend/Resume SSD Cache

A green message will popup: SSD Cache has been suspended

3. Delete the SSD cache.

Select Storage -> Pools & Volume Groups -> Select the SSD Cache -> Uncommon Tasks -> Delete

A green message will popup: The SSH Cache has been deleted

4. Recreate the SSD cache with Security Enabled.

Select Storage > Pools & Volume Groups
Click Create > SSD Cache

Ensure the "Enable Security?" box is checked.
Select both SSD drives.
NOTICE: ensure the checkbox labelled 'Enable SSD Cache on existing compatible volumes that are mapped to hosts' is NOT checked when you recreate the SSD cache.
