RE: Wheezy FCP problem
Hello,
I have already made a port rescan, but the result is the same (no more <wwpn> subdirectory and nothing in the log).
Here are some results of few command :
lsscsi -H -v
[0] zfcp
dir: /sys/class/scsi_host//host0
device dir: /sys/devices/css0/0.0.0003/0.0.4400/host0
[1] zfcp
dir: /sys/class/scsi_host//host1
device dir: /sys/devices/css0/0.0.0002/0.0.3400/host1
The result in dmesg when I chccwdev -e 3400
[ 315.807811] qdio: 0.0.3400 ZFCP on SC 2 using AI:1 QEBSM:1 PCI:1 TDD:1 SIGA: W A

The strange thing is that on the Storage, my host is well seen (symbolic name for example), but I my host the device is not seen.
Should I create an udev rule or something like that ? Did I missed some parameters when loading the zfcp driver ?

please try to write 1 into /sys/bus/ccw/drivers/zfcp/0.0.3400/port_rescan.
Apart from that the output of dmesg would be helpful to see why no port has been detected.
Kind regards
