support.dell.com .
NOTE: The upgrade procedures in this section are applicable to systems running in
a cluster configured with iSCSI Targets and .vhd files in the current active node.
You can also perform these upgrade procedures to upgrade the iSCSI Target on a
stand-alone system.
NOTE: The term 3.0 Target refers to your current configuration of PowerVault NX1950
solution with iSCSI Active/Passive Target 3.0. The term 3.1 Target refers to the
PowerVault NX1950 configuration with Active/Active Target using iSCSI
Active/Active Target 3.1.

10 Configuring 3.1 Target
Planning
If you are retaining the Target names in the new configuration, it is
recommended to record the Target names, location of .vhd files, and the
Target association of the .vhd files as displayed in Table 3-1 below.
Uninstalling the Current Target
To uninstall the current 3.0 Target that is configured in a clustered
environment:
1
Close all applications.
2 Disconnect all Initiators from Target(s). Perform this step from the Initiator.
From the client systems, disconnect all Initiators from the Target(s).
3 Open a Cluadmin interface and delete the previously created
Generic Service from the cluster group.
4 Navigate to Add or Remove programs and uninstall the Microsoft iSCSI
Target from the passive node(s). Reboot each cluster node of the
