iSCSI Initiator

To connect a client (an initiator) to a iSCSI target:

• The following packages need to be installed:

  • RedHat/CentOS/Suse: iscsi-initiator-utils
  • Ubuntu/Debian: open-iscsi

• Make sure that the iscsi service is running.

• Before using a target you must discover it:

   $ iscsiadm -m discovery -t sendtargets -p 192.168.56.10
   192.168.56.10:3260,1 iqn.2013-06.lan.iscsi-storage:storage

• Log in to the new iSCSI target:

   $ iscsiadm -m node -T iqn.2013-06.lan.iscsi-storage:storage -p 192.168.56.10 -l
   Logging in to [iface: default, target: iqn.2013-06.lan.iscsi-storage:storage, portal: 192.168.56.10,3260] (multiple)
   Login to [iface: default, target: iqn.2013-06.lan.iscsi-storage:storage, portal: 192.168.56.10,3260] successful.

• To see the known targets run:

   $ sudo iscsiadm -m node
   192.168.56.10:3260,1 iqn.2013-06.lan.iscsi-storage:storage
