27.2. iSCSI Initiator Creation

Procedure 27.2. Create an iSCSI Initiator

1. Install iscsi-initiator-utils.

   ~]# yum install iscsi-initiator-utils

2. Discover the target. Use the target's IP address, the one used below serves only as an example.

   ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.1
   Starting iscsid:     [ OK ]
   192.168.1.1:3260,1 iqn.2015-06.com.example.test:target1
   

   The above shows the target's IP address and IQN address. It is the IQN address that is needed for future steps.
3. Connect to the target.

   ~]# iscsiadm -m node -T iqn.2015-06.com.example:target1 --login
   Logging in to [iface: default, target: iqn.2015-06.com.example:target1, portal: 192.168.1.1,3260] (multiple)
   Login in to [iface: default, target: iqn.2015-06.com.example:target1, portal: 192.168.1.1,3260] successful.
   

4. Find the iSCSI disk name.

   ~]# grep "Attached SCSI" /var/log/messages
   Jun 19 01:30:26 test kernel: sd 7:0:0:1 [sdb] Attached SCSI disk
   

5. Create a file system on that disk.

   ~]# mkfs.ext4 /dev/sdb

6. Mount the file system.

   ~]# mkdir /mnt/iscsiTest
   ~]# mount /dev/sdb /mnt/iscsiTest
   

7. Make it persistent across reboots by editing the /etc/fstab file.

   ~]# blkid /dev/sdb
   /dev/sdb: UUID="766a3bf4-beeb-4157-8a9a-9007be1b9e78" TYPE="ext4"
   ~]# vim /etc/fstab
   UUID=766a3bf4-beeb-4157-8a9a-9007be1b9e78	/mnt/iscsiTest	ext4	_netdev	0 0
