When an appliance or a host is discovered as a target, it automatically promotes some of the target members. See Target Members of an Oracle ZFS Storage Appliance to view the list of automatically promoted target members. You can choose to either remove the target or remove its members. If you choose to remove a target, such as an appliance or a host, all the associated members are also removed. See Removing a Storage Resource for the steps to remove a storage resource.
You must start the deletion process from the target level to delete all the members.
If the target members have a proper association with an appliance or a host, the deletion of these members is successful. For example, a diskshelf target member is associated to a ZFS Storage Server. If the association of these target members are not correct, diskshelf target members are not deleted.
To remove a storage resource, perform the following steps:
You can view a list of appliance targets under Servers, Storage and Network.
To view the cluster targets, expand Groups, Systems and Services in the left navigation pane. Select a specific cluster target in the right pane.
The target name, target type, and the target status of the selected target is displayed in the right pane.
Right-click on the target name which you want to remove in the right pane.
Click a specific target name in the right pane, and then click the target drop-down list which appears to the top-left of the user interface.
You can delete an Oracle ZFS Storage Appliance which is part of a cluster. See Removing a Storage Resource for steps to delete an Oracle ZFS Storage Appliance. When two Oracle ZFS Storage Servers have a cluster configuration setup, the deletion of cluster target initiates deletion of both the storage servers in the cluster and the associated target members, such as, diskshelves. The members of an Oracle ZFS Storage Appliance include the following:
ZFS Storage Server
ZFS Storage Appliance Cluster
When you initiate deletion of one of the storage server that is a part of the cluster configuration setup, the associated cluster target is deleted. The other storage server is not deleted. The diskshelves are not deleted if there is a second storage server.
When you initiate deletion of a storage server that is not a part of the cluster configuration setup, the associated diskshelves are deleted.
