Select create replica if you want the same configuration for other device. Here uncheck the create replica and click next.
Choose the target attachment mode to unassigned as we didnt create the target node.
Now click on next. It will display the summary of the device. And it is not attached to any target.
Now the disk is attached to the device. But it is not connected to any target.
Client Side configuration:
Here Client IP is 192.168.200.8
Check whether the iscsi initiator is installed in the machine or not
Rpm qa |grep i iscsi
If the iscsi-initiator is not installed. Then install the iscsi-initiator-utils package
Check the IQN no. of the server.
Adding the Client to the target :
Open starwind management console. Right click on the devices on the left pane.
Select Attach to target option.
Select create new target option. Click next
Give the IQN no in the target alias. ( we can give the ip address also but it is less secured)
Here I gave the IP address.

Configuring ISCSI in the client :
The iscsi configuration file location is /etc/iscsi/iscsid.conf.
Open the iscsi configuration file
Change the following in the file and save the file.
Now start the iscsi service :
Discovering the Target :
iscsiadm --mode discovery -t sendtargets --portal
iscsiadm --mode discovery -t sendtargets --portal 192.168.60.124
It will generate a unique iqn no. to connect to the target.
Connecting to the target:
iscsiadm -m node --targetname "IQN No " --portal "Storage IP : port" --login
iscsiadm -m node --targetname "iqn.2008-08.com.starwindsoftware:192.168.60.124-192.168.200.8" --portal "192.168.60.124:3260" login
To check the SAN is mounted or not in the client.
To disconnect from the SAN:
To disconnect from the SAN first unmount the mounted SAN disk from the server.
iscsiadm -m node --targetname "iqn no." --portal "storage ip" logout
iscsiadm -m node --targetname "iqn.2008-08.com.starwindsoftware:192.168.60.124-192.168.200.8" --portal "192.168.60.124:3260" --logout
