7장. Configuring an iSCSI initiator

Procedure

1. Install iscsi-initiator-utils on client machine:

   # dnf install iscsi-initiator-utils

2. Start the iscsid service:

   # systemctl start iscsid

3. Check the initiator name:

   # cat /etc/iscsi/initiatorname.iscsi
   
   InitiatorName=iqn.2006-04.com.example:888

4. If the ACL was given a custom name in Creating an iSCI ACL, update the initiator name to match the ACL:

   1. Open the /etc/iscsi/initiatorname.iscsi file and modify the initiator name:

      # vi /etc/iscsi/initiatorname.iscsi
      
      InitiatorName=custom-name

   2. Restart the iscsid service:

      # systemctl restart iscsid

5. Discover the target and log in to the target with the displayed target IQN:

   # iscsiadm -m discovery -t st -p 10.64.24.179
       10.64.24.179:3260,1 iqn.2006-04.com.example:444
   
   # iscsiadm -m node -T iqn.2006-04.com.example:444 -l
       Logging in to [iface: default, target: iqn.2006-04.com.example:444, portal: 10.64.24.179,3260] (multiple)
       Login to [iface: default, target: iqn.2006-04.com.example:444, portal: 10.64.24.179,3260] successful.

   Replace 10.64.24.179 with the target-ip-address.

   You can use this procedure for any number of initiators connected to the same target if their respective initiator names are added to the ACL as described in the Creating an iSCSI ACL.

6. Find the iSCSI disk name and create a file system on this iSCSI disk:

   # grep "Attached SCSI" /var/log/messages
   
   # mkfs.ext4 /dev/disk_name

   Replace disk_name with the iSCSI disk name displayed in the /var/log/messages file.

7. Mount the file system:

   # mkdir /mount/point
   
   # mount /dev/disk_name /mount/point

   Replace /mount/point with the mount point of the partition.

8. Edit the /etc/fstab file to mount the file system automatically when the system boots:

   # vi /etc/fstab
   
   /dev/disk_name /mount/point ext4 _netdev 0 0

   Replace disk_name with the iSCSI disk name and /mount/point with the mount point of the partition.
