Editing server connections
You can edit the following fields for a server connection:
•
Description
•
Controlling Server IP Address
•
Load balancing
•
CHAP options
CAUTION: If you change the load balancing or CHAP options, you must log off and log back
on to the target in the iSCSI initiator for the changes to take effect.
You can also delete a server connection from the management group. For more information, see
“Deleting server connections” (page 200) .
CAUTION: Editing the iqn or CHAP server settings may interrupt access to volumes. If necessary,
or if the server is sensitive to disconnections, stop server access before editing a server.
1. In the navigation window, select the server connection you want to edit.
2. Click the Details tab.
3. Click Server Tasks, and select Edit Server.
4. Change the appropriate information.
5. Click OK when you are finished.
6. If you have changed the Enable Load Balancing option, a message opens, notifying you to
log servers off and back on to the volumes.
This may entail stopping the applications, disconnecting them, reconnecting the applications
to the volumes, and then restarting them.
Deleting server connections
Deleting a server connection stops access to volumes by servers using that server connection.
Access to the same volume by other servers continues.
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
“Server connection permission levels” (page 204) . For more
information about iSCSI load balancing, see “iSCSI load balancing” (page 231) .
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
