Hello,
I have been attempting to get a Hitachi SAN attached to a FreeBSD box
via a Qlogic 2300 card. The card appeared to work ok (as evidenced
by verbose boot messages but no disk(s) was seen. Finally was able
to see disk with a 'camcontrol rescan 1:0:4' command. Previous
'camcontrol rescan all' and 'camcontrol rescan 1' failed to see disk.
(and obviously not seen at boot time).
I did not set the SAN up but from a cursory examination:
The SAN has two controllers and two 'logical' raid 5 devices.
One controller is connected to a Sun box which sees c1t0d[0-3]
and the 4th lun appears to be given over to the second controller for
the FreeBSD box.
I assume this means that CAM does not probe all LUN's if no device at LUN 0
or sys/cam/cam_xpt.c has quirk entry for device that disables LUN probing.
There is quirk for {"HITACHI", "DK31*"} but the SAN reports as Hitachi DF600F
(I think, sorry its at work and I cannot access it currently)
so the second case shouldn't be a problem.
Am I reading this correctly?
thanks
