Using Backup Software with the iSCSI 

Initiator

When using backup software with the Microsoft® iSCSI Initiator, the iSCSI Initiator ser-
vice needs to start before the backup software services. This ensures the backup soft-
ware will be able to detect the SCSI devices that the iSCSI Initiator logs into. This
requires starting the services in a specific sequence.

To do this, you can use system dependencies to make one service start before another.
By setting up the correct dependencies, you can create a chain reaction and thus start
the services in the correct sequence. 

The following instructions explain how to set up the dependencies for a backup product:

1. Run the Windows Registry Editor by opening 

 using 

Start > Run... 

2. Go to 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

3. Make sure each backup software service has a 

DependOnService

 value. If the

DependOnService

 value does not exist for the service, you must create it:

A Select the service in the folder tree.

B Select 

Edit > Add value... from the menu bar

C Enter the 

Value Name 

DependOnService

D Select 

REG_MULTI_SZ

 for the 

E Click OK

4. Make the value 

DependOnService

 set to the names of services you want started before

the service itself starts. For backup software services, make sure to include the iSCSI
