Step1: Discovering the LUN on Server

#iscsiadm -m discovery -t sendtargets -p 192.9.1.105

#iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.05d8f0355e34 -p 192.9.1.105 -l

#iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.05d8f0355e34 -p 192.9.1.105 --op update -n node.startup -v automatic

Note: Change the blue highlighted value from the Output value of iscsiadm -m discovery -t sendtargets -p 192.9.1.105 command as shown below

Step2: Verify the Disks on the Server
