1. In the navigation window, select the server connection you want to delete. 2. Click the Details tab. 3. Click Server Tasks, and select Delete Server. 4. Click OK to delete the server. Clustering server connections You can cluster servers to easily assign multiple server connections to multiple volumes in a single operation. Cluster existing servers or you can create new servers to add to the server cluster from the New Server Cluster window. If you cluster servers that already have volumes assigned to them, all the servers in the cluster gain access to all the volumes, and inherit the access permissions of the original pair. All clustered servers must have the same load balancing and volume access permission settings. You can verify and update these settings when you create the server cluster. For information about volume access permissions, see Table 60 on page 265. For more information about iSCSI load balancing, see "iSCSI load balancing" on page 300. Requirements for clustering servers • Minimum of two servers for a cluster • Same load balancing setting for all servers • Same access level settings for all volumes assigned to the server cluster Creating a server cluster 1. In the navigation window, select the Servers category. 2. Right-click and select New Server Cluster. 3. Enter a name and description (optional) for the server cluster. 4. Do one of the following: • Click Add Server and select the server from the list of available servers that opens. • Click New Server and follow the instructions found in Adding server connections to manage- ment groups. 5. Add the additional servers required for the server cluster, using either of the above methods. 6. [Optional] Next, click Edit Server Cluster Settings to verify that the server cluster settings are the same for all servers and volumes. NOTE: The Server cluster settings window opens automatically if inconsistencies are detected in the settings for the servers and volumes. P4000 SAN Solution user guide 261
