thanks mark
now I used centos 5.6 2.6.33.7 32bit  SCST is 2.0.0 version MHVTL is 0.18-17 .

After several days of the installation, I solved the issues raised before (mainly kernel too) .

Now I use 2.6.33.7 and the emergence of new problems

when I Installed scst-2.0.0 iscst-2.0.0 scstadm-2.0.0 . I can not find scst.conf, iscsi-scstd.conf
then "scst,iscsi" Service failed to start
centos 5.6 2.6.33.7 support scst2.0.0 do?

mhvtl working properly

I'm using a config similar to your (centos 5.6 with vanilla kernel 2.6.33.7, mhvtl and scst up2date) , and have no problem.

My scst is trunk version obtained via svn (svn co https://scst.svn.sourceforge.net/svnroot/scst/trunk)

Here you are my scst.conf so you can modify it with your spec

the problem remain .

This evening i'll try to make a new system as your and write down all the steps to configure scst.

Also check stgt (another iscsi target) that is more simple to configure and use.

Also:
* I recommend that you install the latest code http://stgt.sourceforge.net/releases/tgt-1.0.18.tar.gz

I try ,but my system is not oracle linux .a lot of command i don't know You can send a copy of your document to a successful operation on scst me ? My mail [e-mail]

[wen]

You know, see the information above you, I am very excited, thank you very much. I have installed mhvtl nearly two weeks, although learning a lot about linux knowledge, but did not complete the iscsi for MHVTL I feel very sorry. I hope you do not mind my English is not very good, I use google translation

Hi Wen,
i've tried an install from scratch and it work perfectly.  Use with windows initiators with no probem.

See this message.
