------

SCENARIO: 

------

ISCSI target : server with IP address 192.168.150.153

ISCSI initiator : client with IP address 192.168.150.152

------

STEP 1: Install the following package:

-------

yum install -y iscsi-initiator-utils

-------

STEP 2: Open the file, /etc/iscsi/initiatorname.iscsi and enter the initiator name configured as acl on target side. 

STEP 3:  Start iscsi service and enable it on boot.

------

systemctl  start iscsi

systemctl enable iscsi

------

STEP 4: Execute the iscsiadm command in discovery mode with the server ip address.

STEP 5:  Now, login to the LUN using iscsiadm and see the result using lsblk.

In dmesg, we can view the logs.

STEP 6: Now, you can see 2 disks sda and sdb is added. Create an xfs filesystem using the block device "/dev/sda" and mount it to directory named "iscsi".

Final result will be as below: 

STEP 7: Enable the services on boot as below:
