Configuring iSCSI Connections 

After the array has been initialized and all needed logical drives have been configured, the iSCSI initiators on 
the application servers will need to be configured in order to mount any logical drives that are configured for the 
application server. Once configured, the logical drives created during the initialization process can be mounted 
by the application server.  

If logical drives were not created during the initialization process or additional logical drives and pools are 
needed, then refer to the 

Configuring Logical Disks and Pools

 

section that appears later in this document 

before continuing with these steps. 

Configuring the iSCSI Initiator in Windows 

To configure the iSCSI initiator on a Windows server, ensure that the port IP address that the application server 
will connect with has been recorded and that the CHAP secret, if used, has also been recorded. 

1.  Launch the iSCSI Initiator properties menu by 

clicking 

Start

 and then 

iSCSI Initiator

. 

2.  In the iSCSI Initiator Properties window, select 

the 

Targets

 tab. In the Targets window, select 

the appropriate array, and then click 

Log On

. 

 

 

 

 

 

 

 

 

 

 

 

 

 

3.  At the Log On to Target window, select the 

Automatically restore this connection when 
the computer starts

 option, and then click 

Advanced

. If you will be using NEC 

PathManager for Multipathing, do not select 
“Enable multi-path”. Otherwise, refer to 
Microsoft’s documentation for information about 
enabling mutlipathing through the Microsoft 
iSCSI software initiator.
