ISCSI on Debian

af Tommy, feb 2013.

Turbo Installation

apt-get install open-iscsi

Edit /etc/iscsi/iscsid.conf

...
node.startup = automatic
...

derefter en restart :

/etc/init.d/open-iscsi restart

Discover LUN:

root@testbox:~# iscsiadm -m discovery -t st -p 192.168.8.31

Output : 192.168.8.31:3260,1 iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976

iscsiadm -m node

Output : 192.168.8.31:3260,1 iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976

... vi springer lige over CHAP ...

Nå, opret forbindelse :

iscsiadm -m node --targetname "iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976" --portal "192.168.8.31:3260" --login

Nu skulle disken kunne findes med

fdisk -l

Man kan detache med --logout :

iscsiadm -m node --targetname "iqn.2004-04.com.qnap:ts-239:iscsi.qnap1.8d8976" --portal "192.168.8.31:3260" --logout

Over 2TB

Ikke kun et iSCSI issue, men Linux kræver GPT for at kommer over 2TB diske:

apt-get install gdisk

gdisk /dev/sdb

Kommandoer:

b	back up GPT data to a file
c	change a partition's name
d	delete a partition
i	show detailed information on a partition
l	list known partition types
n	add a new partition
o	create a new empty GUID partition table (GPT)
p	print the partition table
q	quit without saving changes
r	recovery and transformation options (experts only)
s	sort partitions
t	change a partition's type code
v	verify disk
w	write table to disk and exit
x	extra functionality (experts only)

Så, o, n og w.
