iSCSI Enterprise Target 0.4.14

SuSE 10.2 - iSCSI Enterprise Target 0.4.14

Meine ersten iSCSI Gehversuche sollten mit einem iSCSI-Target Server beginnen. Mein Ziel ist/war es über iSCSI Booten zu können.

Zum testen habe ich mir ein openSuSE 10.2 installiert und die Sourcecodes von iSCSI Enterprise Target 0.4.14 kompiliert.

• Folgende Pakete müssen auf dem Rechner, z.B. mit YaST, installiert sein:
  • gcc
  • make
  • openssl-devel

Entpacken:

linux-san:~/iscsi # tar xfvz iscsitarget-0.4.14.tar.gz
iscsitarget-0.4.14/
iscsitarget-0.4.14/kernel/
iscsitarget-0.4.14/kernel/target_disk.c
iscsitarget-0.4.14/kernel/wthread.c
iscsitarget-0.4.14/kernel/param.c
....

Compilieren:

Konfiguration:

Anpassen der iSCSI-Target Konfiguration /etc/ietd.conf. Hier eine minimale Konfiguration:

Target iqn.2006-01.linux-san:hda4
  Lun 0 Path=/dev/hda4,Type=fileio
  Alias sandisk1

In der Firewall muss der Port TCP 3260 freigegeben werden.

Starten des iSCSI-Targets:

sh /etc/init.d/iscsi-target start

Ausgabe von dmesg:

iSCSI Enterprise Target Software - version 0.4.13
iotype_init(90) register fileio
iotype_init(90) register nullio
