I’m trying to setup iSCSI LIO Target on SLES 11 SP3 after clean install After creating everything in YaST I have: [QUOTE]ili-nas:~/Desktop # service target status [---------------------------] TCM/ConfigFS Status [----------------------------] \------\> iblock\_0 HBA Index: 1 plugin: iblock version: v4.1.0-rc2-ml \-------\> dev\_lvext\_i-data Status: ACTIVATED Max Queue Depth: 0 SectorSize: 512 HwMaxSectors: 4294967288 iBlock device: dm-6 UDEV PATH: /dev/lvext/i-data readonly: 0 Major: 253 Minor: 6 CLAIMED: IBLOCK udev\_path: /dev/lvext/i-data \-------\> dev\_lvnas\_i-win8 Status: ACTIVATED Max Queue Depth: 0 SectorSize: 512 HwMaxSectors: 4294967288 iBlock device: dm-5 UDEV PATH: /dev/lvnas/i-win8 readonly: 0 Major: 253 Minor: 5 CLAIMED: IBLOCK udev\_path: /dev/lvnas/i-win8 [---------------------------] LIO-Target Status [----------------------------] \------\> iqn.2014-01.local.ili-home:win \-------\> tpgt\_1 TargetAlias: LIO Target TPG Status: ENABLED TPG Network Portals: \-------\> 192.168.32.100:3260 TPG Logical Units: \-------\> lun\_1/dev\_lvext\_i-data → target/core/iblock\_0/dev\_lvext\_i-data \-------\> lun\_0/dev\_lvnas\_i-win8 → target/core/iblock\_0/dev\_lvnas\_i-win8 Target Engine Core ConfigFS Infrastructure v4.1.0-rc2-ml on Linux/x86\_64 on 3.0.76-0.11-default RisingTide Systems Linux-iSCSI Target v4.1.0-rc2 running ili-nas:~/Desktop # [/QUOTE] and in /etc/target there are no files lio\_setup.sh and tcm\_setup.sh.

Hi andy\_s, I’ll forward your change suggestion (including your question and comments, of course) to my SuSE contacts and will ask for some developer to look into this. Of course I cannot promise on any result, but if there’s something useful to report back, I’ll do so 🙂 Regards, Jens
