Configuring advanced features

 

Microsoft iSCSI Software Target’s snapshot feature extends Microsoft Volume Shadow Copy Service 

(VSS) to enable snapshots (shadow copies) of Microsoft iSCSI Software Target Disks for enhanced 

data protection. VSS stores shadow copies on an NTFS volume that is user-configurable. To ensure 

that shadow copies are retained when a failover occurs, the shadow storage area needs to be 
configured to use a volume on the shared disk device. This section details the steps involved in 

configuring the shadow storage location.  
 

1. 

Log in to the active cluster node and launch the Microsoft iSCSI Software Target Console. 

2. 

Select the Devices node. Right-click the first Microsoft iSCSI Software Target Disk in the list 
view, and select Properties. The Microsoft iSCSI Software Target Disk properties notebook is 
displayed. 

3. 

Select the Snapshot Storage tab. This page contains the configuration information for the shadow 

copies of this Microsoft iSCSI Software Target disk. 

4. 

Ensure that the shadow storage volume is the same as the location of the Microsoft iSCSI Software 
Target disk file. For example, if the Microsoft iSCSI Software Target disk file path is 
E:\win2003client.vhd, then select E:\ from the list to be the shadow storage location. Click OK to 

save the settings. 

5. 

Repeat the above steps for other remaining Microsoft iSCSI Software Target disks. 

 
Another advanced feature of Microsoft iSCSI Software Target is the ability to schedule snapshot and 

local mount operations to occur on a regular basis for backup and restore purposes. Microsoft iSCSI 
Software Target uses Windows Task Scheduler Service to facilitate this operation. In order for the 

scheduling configurations to propagate correctly during a failover, the Windows Task Scheduler 

Service needs to be configured as a cluster resource. This section describes the steps involved. 
 

Important 

Configuring Windows Task Scheduler as described in this 

section will create an active/passive Task Scheduler. This 

means that Windows Task Scheduler will only run on the 
active cluster node.  

 
The first step is to change the location where Task Scheduler stores the schedule information. By 

default, this location is the system root folder. This needs to be changed to use the volume on the 
shared cluster disk.  

 

1. 

Log in to the active cluster node and launch the Registry Editor. 

 

Warning

 

Improper use of the Registry Editor can render the system 
unbootable.
