====== Booting debian over iscsi ====== Here I will be documenting my first attempt to boot linux over iscsi. ===== Reason to choose debian ===== - Chose debian because the squashfs of debian works fine and there are no other problems. - Also, all the kernel modules needed for iscsi initiator are inside initramfs so, less work for me. :-) - No considerable success yet :-( ===== Installing the target ===== The target for these experiments is installed on my laptop (Ubuntu-9.04) with following procedure. Most of these steps are taken from blog [[http://www.howtoforge.com/using-iscsi-on-ubuntu-9.04-initiator-and-target|Using iscsi over ubuntu 9.04]]\\ Installing iscsi target <code> sudo apt-get install iscsitarget </code> Configure the target by editing ''/etc/default/iscsitarget'', ''/etc/ietd.conf'' and ''/etc/initiators.allow'' files as follows\\ - Open ''/etc/default/iscsitarget'' and set ''ISCSITARGET_ENABLE=true'' - Open ''/etc/ietd.conf'', and comment out all lines, then add following paragraph <code> Target iqn.2001-04.com.example:storage.lun1 IncomingUser OutgoingUser Lun 0 Path=/var/www/debian-live-501-i386-gnome-desktop.iso,Type=fileio,IOMode=ro Alias LUN1 </code> Now we add following line to "/etc/initiators.allow" <code> ALL ALL </code> This should allow any initiator to access any lun device\\ and then, restart the target <code> sudo /etc/init.d/iscsitarget restart </code> ===== Testing the target ===== The iscsi target is tested by installing iscsi initiator on same laptop. Following is the procedure.\\ * Installing configure iscsi initiator to start nodes automatically Edit the file "/etc/iscsi/iscsid.conf" to have line "node.startup = automatic" vi /etc/iscsi/iscsid.conf node.startup = automatic and then restart the initiator /etc/init.d/open-iscsi restart then do the discovary iscsiadm -m discovery -t st -p 192.168.0.101 I dont know why this command is needed, but it was there so I am adding it iscsiadm -m node Logging in iscsiadm -m node --targetname "iqn.2001-04.com.example:storage.lun1" --portal "192.168.0.1:3260" --login fdisk -l
