Step 1: Select the site

As your first step, you must access the Decommission Site page to determine if the site can be decommissioned.

Before you begin

You must have contacted your NetApp account representative to enable the Decommission Site page.
You must have obtained all required materials.
You must have reviewed the considerations for decommissioning a disconnected site.
You must be signed in to the Grid Manager using a supported browser.
You must have the Root Access permission, or the Maintenance and ILM permissions.
The Connection State on the Nodes > Overview tab must be Unknown or Administratively Down for every node in the site.
The site must not include the primary Admin Node or an Archive Node.

Procedure

Select Maintenance. Then, in the Maintenance Tasks section of the menu, select Decommission.
The Decommission page appears.
Click the Decommission Site button.
Step 1 (Select Site) of the Decommission Site page appears. This page includes an alphabetical list of the sites in your StorageGRID system.

Attention: If the Decommission Site page has not been enabled, an error message appears when you click Decommission Site. You must contact your NetApp account representative. NetApp will review your requirements before enabling the Decommission Site page. After the page is enabled, you can return to this procedure.
In the Sites table, view the value for each site in the Used Storage Capacity column.
The Used Storage Capacity is an estimate of the total storage used for object copies, erasure coded fragments, and object metadata at the site. If nodes are offline, the Used Storage Capacity is the last known value for the site. The value for Used Storage Capacity represents how much of your system's data storage will become inaccessible when you decommission this site.
Note: If your ILM policy was designed to protect against the loss of a single site, copies of your object data should still exist on the remaining sites.

In the Site table, review the reasons in the Decommission Possible column to determine which sites can be decommissioned currently.

Note: If there is more than one reason a site cannot be decommissioned, the most critical reason is shown.

Decommission Possible reason	Description	Next steps
Green checkmark	You can decommission this site; however, you might need to update ILM rule definitions.	Go to step 5.
No, this site contains the primary Admin Node.	You cannot decommission a site containing the primary Admin Node.	None. You cannot perform this procedure.
No, this site contains one or more Archive Nodes.	You cannot decommission a site containing an Archive Node.	None. You cannot perform this procedure.
No, one or more nodes at this site are in a high availability (HA) group.	You cannot decommission an Admin Node or a Gateway Node that is used in a high availability (HA) group.	Edit HA groups to remove all nodes at the site. Or, remove an HA group if it only includes nodes from this site. Then, return to this page to see if site decommissioning is possible. Administering StorageGRID
No, one or more nodes at this site are online.	You cannot decommission a site if any node in the site has a Connection State of Connected on the Nodes > Overview tab.	Contact technical support.

For example, this page shows a StorageGRID system with three sites. The green checkmark for the Raleigh site in the Decommission Possible column indicates that you can decommission that site. However, you cannot decommission the Sunnyvale or Vancouver sites.

If decommission is possible, select the radio button for the site.
The Review Site button is enabled.
Click Review Site.
Step 2 (Review) of the Decommission Site page appears.
