Procedure 25.7. Creating an iSCSI Initiator

1. Install iscsi-initiator-utils:

   # yum install iscsi-initiator-utils -y

2. If the ACL was given a custom name in Section 25.1.6, “Configuring ACLs”, modify the /etc/iscsi/initiatorname.iscsi file accordingly. For example:

   # cat /etc/iscsi/initiatorname.iscsi
   InitiatorName=iqn.2006-04.com.example.node1
   
   # vi /etc/iscsi/initiatorname.iscsi

3. Discover the target:

   # iscsiadm -m discovery -t st -p target-ip-address iscsiadm -m discovery -t st -p target-ip-address iscsiadm -m discovery -t st -p target-ip-address 
   10.64.24.179:3260,1 iqn.2006-04.com.example:3260

4. Log in to the target with the target IQN you discovered in step 3:

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

   This procedure can be followed for any number of initators connected to the same LUN so long as their specific initiator names are added to the ACL as described in Section 25.1.6, “Configuring ACLs”.
5. Find the iSCSI disk name and create a file system on this iSCSI disk:

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

   Copy to Clipboard Toggle word wrap
   Replace disk_name with the iSCSI disk name displayed in /var/log/messages.
6. Mount the file system:

   # mkdir /mount/pointmkdir /mount/point
   # mount /dev/disk_name /mount/pointmount /dev/disk_name /mount/pointmount /dev/disk_name /mount/pointmount /dev/disk_name /mount/point

   Copy to Clipboard Toggle word wrap
   Replace /mount/point with the mount point of the partition.
7. Edit the /etc/fstab to mount the file system automatically when the system boots:

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

   Copy to Clipboard Toggle word wrap
   Replace disk_name with the iSCSI disk name.
8. Log off from the target:

   # iscsiadm -m node -T iqn.2006-04.com.example:3260 -uiscsiadm -m node -T iqn.2006-04.com.example:3260 -uiscsiadm -m node -T iqn.2006-04.com.example:3260 -u
