Hi all,
I am playing with the LIO target stack for Fibre Channel with two
openSUSE hosts as initiator and target. (Yes, I am fully aware of the
state of LIO wrt FC)
(Apologies for the legnth of this, however I have no hair left to pull
out...)
I've been trying to follow the instructions in:
http://www.linux-iscsi.org/wiki/QLogic
substituting targetcli for rtsadmin.
The modules on the target appear to be correctly loaded. However I did
notice that a tree of /sys/kernel/config/target does not match what the
wiki page has for the configfs output. In particular, I do not seem to
have the "mapped_luns" output.
End result is the initiator is not initializing the qla2xxx module
correctly, dmesg on that node says that the cables are unplugged. They
are plugged. I do not see the lun on the initiator.
Both nodes are opensuse 12.1, with the target having the lio kernel
source as of Feb 15. The initiator is a fully patched openSUSE 12.1.
Both nodes have a QLogic QLE2462 - PCI-Express Dual Channel 4Gb Fibre
Channel HBA card in them. Both nodes have the qlogic's bios set to 4GB
transfer rates. I did not upgrade firmware on either node.
What I did to create the config via targetcli was (essentially):
> cd /backstores/fileio
> create lio /dev/sdb
> cd /
> cd tcm_fc
> create
> create /backstores/fileio/lio 0
> exit
Here is a ls of the targetcli shell:

This does not match the wiki page for the qlogic configfs tree at all.
What am I missing?
Thanks
