So,
I have a QLA2342 (ISP2312 chip) that i am trying to use as a FC
target. ( well i have two i want to use as targets and two as
initiators )
The targetcli util loads the modules and seems to work correctly. When
i go to create a target in the qla2xxx/ directory, the command never
returns and hangs indefinitely.
After some debugging i have found that the
qlt_24xx_process_atio_queue( ) function has a while loop that never
exits. This while loop in particular:
while (ha->tgt.atio_ring_ptr->signature != ATIO_PROCESSED) {
"ha->tgt.atio_ring_ptr->signature" seems to always be zero.
Another problem i noticed is that the variable "cnt" is always zero.
Thus the for loop is always skipped, which skips the part where the
signature is changed ( i think ).
I am running a 3.6.1 kernel with a tiny modification to have the card
start up in target mode by default:
I replaced:
static char *qlini_mode = QLA2XXX_INI_MODE_STR_ENABLED;
with:
static char *qlini_mode = QLA2XXX_INI_MODE_STR_DISABLED;
Here is a look at the lspci -vv of the QLogic card:

Thoughts anyone? I really could use some help.
I did manage to get a FC target running with openfiler and SCST but i
do not like running 2.6 kernels much.
