Hello,
I'm trying to work with SCSI target over FCoE. (using fileio sample
of SCST)
I'm using Linux 3.8.13 , Intel 10G card and HP5900 switch with VSAN
10 for
FCoE.
I am not familiar with the SCST commands to be able to tell you if
you're using it right. I might be able to give you some pointers to
help debug though.
The problem is that the target doesn't send FLOGI to the switch.
(I have windows client that works with the same switch and configuration
and succeed to login)
The following is the operation sequence I perform:
- vconfig add eth2 10
- load scst, scst_user
- fileio_tgt disk0 file0 disk1 file1
- modprobe fcoe
- echo eth2.10 > /sys/module/libfcoe/parameters/create_vn2vn (fcoeadm -c
eth2.10 returned an error)
I'm using TCM, not SCST, but VN2VN with a VLAN worked for me.
I have debug logging on for libfcoe on both systems.
# echo 0xFFFF > /sys/module/libfcoe/parameters/debug_logging
