Designating a primary site
Use the Primary designation when you are using the Multi-Site cluster to maintain a primary site
and a second site as a backup site. Designate the site as Primary when you create the site, or you
can edit an existing site to make it primary. Only one site can be designated as Primary in a
Multi-Site cluster. Make sure that the majority of managers are in the Primary site.
Adding a site
Create new sites directly in the CMC if you want to add a site to an existing cluster. You must have
equal numbers of storage systems in each site. The Failover Manager can occupy a site by itself.
1. Select the Sites node in the navigation window.
2. Right-click and then select New Site.
3. Type in a site name and optional description.
4. (Optional) If you are setting up a primary configuration, select the Primary box.
5. In the Site Systems section, click Add to add storage systems to the site.
6. Select the appropriate systems, and click OK when you are finished.
7. In the Site Servers section, click Add to add servers to the site.
8. Select the servers, and click OK when you are finished.
9. Click OK again when you have finished creating the new site.
The Sites Details tab displays the new site with its storage systems and servers.
Editing a site
You can edit any aspect of the site, including:
• Changing the name and description of the site
• Changing the primary designation
NOTE: Only one site can be primary.
• Adding or removing systems.
IMPORTANT: All sites must have the same number of storage systems, except for the Failover
Manager, which can reside in a site by itself.
• Adding or removing servers.
To edit a site
1. Right-click the Sites node in the navigation window and then select Edit Sites.
2. Select the site you want to edit and then click Continue.
3. Make the desired changes.
4. Click OK when you are finished.
Deleting a site
You would delete a site from a Multi-Site cluster when you are either reconfiguring your SAN or
recovering from a disaster or other failure.
When only one site will be left in the cluster, deleting a site changes the cluster from a Multi-Site
cluster to a standard cluster. If you then remove the storage system(s) assigned to that site, data
that resides on the cluster will restripe.
