Missing /sys/kernel/config/target

[alan.brunelle]

I believe I've followed the instruction correctly - I'm at commit:

commit 33818533e835b3dbaddb45acfc90c7406fffbcee
Author: Nicholas Bellinger <n...@linux-iscsi.org>
Date: Mon Aug 10 09:02:27 2009 -0700

for lio-core, and when I load the target module, I do see in the dmesg
output:

x86_64 on 2.6.31-rc5-iscsi-tgt

However, when I attempt to issue a tcm_node command, I get errors
trying to find stuff under /sys/kernel/config/target/...:

tcm_node --listhbas

Am I missing some step? Where should I look? [I'm adding printk's to
the code whilst I await any suggestions...]

I think this is because (primarily? exclusively?) I don't have a
/etc/target/tcm_start.sh file (or a /etc/target/lio_start.sh neither).
Are there generic ones, or is this something /I/ need to figure out?

Thanks,

Ah! I mounted configfs and I'm making some progress...

Greetings Alan,

Good to hear you are getting up and running with the latest code!

Btw, the configfs modprobe and mount is happening in
lio-utils.git/scripts/rc.target init.d in target:check_configfs_mount(),
which I figured was easier than expecting everyone to add it
to /etc/fstab.. :)

So have you been able to get TCM storage objects and iSCSI Target ports
up and running on your setup..?

Also, the user's reference manual for v3 CLI ops which might help you
out is now available from:

http://linux-iscsi.org/builds/docs/LIO-3.0-Users_Reference_Manual.pdf

Please feel free to post your progress to the list if you run into any
any issues or comments,

Thanks!
