Topology 1.ISCSI target server configuration 1.Add the new node (node3) to the ACLs list. This is the existing setting. Here are the commands I used. 2. Enable and restart the target service. systemctl enable target.service systemctl restart target.service 2.ISCSI initiator configuration. Configure ISCSI initiator in the new node (node3) 1.Install iscsi-initiator-utils in all nodes. sudo yum install iscsi-initiator-utils -y 2.Edit the /etc/iscsi/initiatorname.iscsi , replace the existing value with following keywords, the one I used in step 4 of section[ISCSI target server configuration] InitiatorName=iqn.2020-08.com.contoso:node3 3.Discover iSCSI disk of the target. iscsiadm -m discovery -t st -p <ip of iscsi target server>
