Hi,
Well, I finally had a chance to set up a fibre channel target system
with kernel
3.12. Unfortunately, demo mode still doesn't appear to work for me. Here's
what I have:
Initiator Fedora 18
kernel 3.10.4-100
QLogic QLE2562 HBA
Target Fedora 20
kernel 3.12.6-300
QLogic QLE2462 HBA
targetcli 2.1.fb30-1
rtslib 2.1.fb40-1
configshell 1.1.fb9-1
I set things up as below:
-----------------------------------------------------------------------------
o- / ..................................................................
[...]
o- backstores .......................................................
[...]
| o- block ........................................... [Storage
Objects: 1]
| | o- strg .................. [/dev/md_d0 (238.5GiB) write-thru
activated]
| o- fileio .......................................... [Storage
Objects: 0]
| o- pscsi ........................................... [Storage
Objects: 0]
| o- ramdisk ......................................... [Storage
Objects: 0]
o- iscsi .....................................................
[Targets: 0]
o- loopback ..................................................
[Targets: 0]
o- qla2xxx ...................................................
[Targets: 2]
| o- naa.21000024XXXXXXXe ......................................
[gen-acls]
| | o- acls .....................................................
[ACLs: 0]
| | o- luns .....................................................
[LUNs: 1]
| | o- lun0 ................................... [block/strg
(/dev/md_d0)]
| o- naa.21000024XXXXXXXf ......................................
[gen-acls]
| o- acls .....................................................
[ACLs: 0]
| o- luns .....................................................
[LUNs: 1]
| o- lun0 ................................... [block/strg
(/dev/md_d0)]
o- vhost .....................................................
[Targets: 0]
-----------------------------------------------------------------------------
To enable demo mode I issued the following:
targetcli /qla2xxx/naa.21000024XXXXXXXe set attribute\
demo_mode_write_protect=0 generate_node_acls=1 cache_dynamic_acls=1\
demo_mode_login_only=0
This responded with:
Parameter demo_mode_login_only is now '0'.
Parameter demo_mode_write_protect is now '0'.
Parameter generate_node_acls is now '1'.
Parameter cache_dynamic_acls is now '1'.
Unfortunately, nothing I do enables the initiator to see the target machine.
Rebooting the initiator or issuing a link initialization and scan don't
help.
What does work is to add the initiator WWPNs to the target's acls which
is, of
course, what demo mode is supposed to dispel.
This works:

Am I missing something?
After waiting 6 months and being assured that this would be fixed in
3.12 it is a bit frustrating not be able to get this to work. I know
since I identified the issue 6 months ago a couple of other people
have also queried the list concerning this feature.
I hope I'm just overlooking something.
Thanks for any insight,
Craig Watson
