====== Creating an iSCSI target on Linux ======

===== Creating a disk image =====

Create an empty file to be the disk image:

    dd if=/dev/zero of=/path/to/image/file.img bs=1M count=0 seek=8192

where ///path/to/image/file.img// is the path where you want to store the disk image file, and //**8192**// is the size of the disk image that you want to create, in megabytes.

===== Creating an iSCSI target =====

Edit the file ///etc/ietd.conf// and add:

    Target iqn.2007-08.name.dns.target.my:iscsiboot
        Lun 0 Path=/path/to/image/file.img,Type=fileio

where ///path/to/image/file.img// is the path to your disk image file, and //name.dns.target.my// is your DNS name in reverse order.

(For completeness, you should also replace //2007-08// with the year and month in which you first obtained your DNS domain.  The iSCSI naming schemes are somewhat pedantic, but it won't affect anything in practice; as long as the target name is unique then everything will work just fine.)

Restart the iSCSI target service:

    /etc/init.d/iscsi-target restart

Make a note of the iSCSI target IQN that you chose (//iqn.2007-08.name.dns.target.my:iscsiboot// in the above example).  You are now ready to:

  * [[sanboot:iscsi_install|Install to the iSCSI target]]
