CentOS :: Connecting iSCSI device

In this guide we will see how to add an iSCSI device into XenServer (version 6.5 and above). In this guide we will use iSCSI device mapped into a FreeNAS box. You can see here how to create iSCSI device using FreeNAS.

1. Install iscsi-initiator-utils:

1. # yum install iscsi-initiator-utils -y

Start the iscsi service:

systemctl start iscsi
systemctl enable iscsi

2. Get the IQN of you machine (for configuring at the FreeNAS):

# cat /etc/iscsi/initiatorname.iscsi

3. Discover the target (ISCSI Storage FreeNAS)

# iscsiadm -m discovery -t st -p Your-Target-IP-Address

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

# iscsiadm -m node -T iqn.xxxx-xx.xxx.example -l 

5. Create a file system:

Find the ISCSI disk:

# lsblk --scsi

# mkfs.ext4 /dev/sdd

6. Mount your ISCSI storage:

# mount /dev/sdd /mnt

7. You can mount the iSCSI storage automatically when system boots:

# vi /etc/fstab

Add the line:

/dev/sdd /mnt ext4 _netdev 0 0
