Fibre Channel card initialization

I had a new SUN M4000 server with two identical QLOGIC FC cards installed. The first FC interface came up without any problem and I kind of forgot about the second one.

Well, in order to move the server into production I needed to multipath the two cards together using the stmsboot -e command, but the second card wasn't responding. I checked the physical connections between the FC switch and the server, but that wasn't it. I tried to poke the system using the cfgadm command -- no luck...

# luxadm -e port
/devices/pci@3,700000/SUNW,qlc@0/fp@0,0:devctl CONNECTED
/devices/pci@2,600000/SUNW,qlc@0/fp@0,0:devctl NOT CONNECTED

No commands would bring the card to life so the FC switch wouldn't see anything attached to the port.

After a lot of troubleshooting I took it to basics and halted the system and reset the bus:

{1} ok
{1} ok reset-all
{1} ok probe-scsi-all

now the second card was responding, so I rebooted the server:

{1} ok boot -rv.

and now it's fine...
