5.1.7 Redundant virtual target

The access path to a virtual disk must be in a multi-path configuration. Thus, you must copy information from a virtual target (to which a virtual disk is already assigned) to any other virtual target and add the same information to both virtual targets.

1. Start up the "Copy Virtual Target" dialog box as follows:

   • Select from the Composition Data tree area the copy source virtual target and then [Operations] - [Virtual Target] - [Redundant], or

   • Right-click on the copy source virtual target and select [Redundant Virtual Target].

2. The "Redundant Virtual Target" dialog box then appears.

   

3. Select the following status information from the "Redundant Virtual Target" dialog box.

   Virtual Target Name (selection required)

   Select a copy destination virtual target (you can only select one).

   For the VS900 Model 300 and Virtualization Blade, switch device names are displayed as "virtualization switch name (host name)".

4. Click the <OK> button in the "Redundant Virtual Target" dialog box.

5. The "Redundant Virtual Target" confirmation dialog then appears. Click the <OK> button.

6. The "Redundant Virtual Target" dialog displays the virtual target copy result. Click the <Close> button.

7. Confirm on the display and the creation screen that the virtual target has been copied to the virtual target.

   The virtual target will now be copied.

Note

• No virtual disk shall be assigned to the copy destination virtual target.

• If the number of SCSI command queues of the virtual target exceeds the number of SCSI command queues of a single CA, a confirmation dialog box appears with the message "ssgui4414: The number of virtual targets of SCSI command cues exceeds the limitation value of CA. Is processing continued?". If you click the <OK> button, disk read or write performance may deteriorate.
