REDHAT 7: ISCSI initiator configuration

In this post, I will discuss about the configuration of an initiator server. Before starting with this one, make sure that you have gone through my previous post about ISCSI target:

-------

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:
