===== iSCSI =====

==== iSCSI Initiator ====

To Get iSCSI Initiator run on linux install

  apt-get install open-iscsi
  
and

  iscsiadm -m discovery -t sendtargets -p <iSCSI Targethost>   #<iSCSI Targethost> = IP of the iSCSI Target

This will discover the target such as 

  192.168.1.10:3260,1 iqn.2006-01.com.openfiler:tsn.c0e878a1bece

To login use:

  iscsiadm --mode node --targetname iqn.2006-01.com.openfiler:tsn.c0e878a1bece --portal 192.168.1.10:3260 --login
  
Automtically load target after reboot system (replaces previus command!)

  iscsiadm -m node -T iqn.2006-01.com.openfiler:scsi.linux3-data-1 -p 192.168.2.195 --op update -n node.startup -v automatic
  
Finally run

  /etc/init.d/open-iscsi restart
  
and there should be a new device such as /dev/sdX 

which you can format with fdisk, make filesystem (mkfs.extX) and mount
