. You must manually change the server and volume associations to the desired
configuration after deleting the server cluster.
Figure 86 Servers and volumes retain connections after server cluster is deleted
1. Each volume remains connected to each server after the server cluster is deleted
To delete a server cluster and remove connections:
1.
In the navigation window, select
Servers
and then select the server cluster to delete.
2.
Right-click on the server cluster and select
Delete Server Cluster
.
3.
Select a server to change associations.
4.
Right-click and select
Assign and Unassign Volumes and Snapshots
.
5.
Select the appropriate volume and permission level for that server, and click
OK
.
6.
Repeat these steps for the remaining servers, until the appropriate server and volume
connections are in place.
Assigning iSCSI server connections access to volumes
After you add an iSCSI server connection to your management group, you can assign one or more
volumes or snapshots to the server connection, giving the server access to those volumes or
snapshots.
CAUTION:
Without the use of shared storage access (host clustering or clustered file system)
technology, allowing more than one iSCSI application server to connect to a volume at the same
time, without cluster-aware applications and/or file systems in read/write mode, could result in
data corruption.
You can make the assignments in two ways:
•
“Assigning server iSCSI connections from a volume” (page 206)
•
“Assigning volumes from an iSCSI connection” (page 206)
Prerequisites
•
The server connections you want to assign must already exist in the management group. See
“Planning server connections to management groups” (page 198)
.
•
The volumes or snapshots you want to assign must already exist in the management group.
When you assign the server connections and volumes or snapshots, you set the permissions that
each server connection will have for each volume or snapshot. The available permissions are
described in
Table 65 (page 206)
.
