If you are using Windows Server 2008 Core Version

1

Set the iSCSI initiator services to start automatically (if not already set):

sc \\<server_name> config msiscsi start= auto

2

Start the iSCSI service (if necessary):

sc start msiscsi

3

than one session to be logged in to a target at one time.

<

<

Password

 is the target CHAP secret.

<

Authtype
