hello, I'm having trouble running Wheezy in z/VM 6.2. I try to access scsi lun with fcp driver but this doesn't work. Wheezy is installed running on eckd dasd, but now I'd like to test FCP lun. I have s390-tools version 1.16.0-2 installed. Kernel 3.2.0-4-s390x We use NPIV. Storage and SAN seems wel l configured. On z/VM side in the USER DIRECT C, I have dedicate 3400 3400 dedicate 4400 4400 On debian side, when I made a "vmcp q fcp all", I see my 2 devices : FCP 3400 ATTACHED TO DEBIAN3 3400 CHPID 30 WWPN C05076E7E3800000 FCP 4400 ATTACHED TO DEBIAN3 4400 CHPID 40 WWPN C05076E7E3800680 But a chccwdev -e 3400 or chccwdev -e 4400 does nothing. I have the /sys/bus/ccw/drivers/zfcp/0.0.3400 directory, but not the <wwpn> subdirectory. I referred to the IBM's doc "Linux on System z Device Drivers, Features, and Commands
Development stream (Kernel 3.2)" SC33-8411-14. Also made a "lszfcp -P -H -D -V" and the result is the following. /sys/devices/css0/0.0.0002/0.0.3400 /sys/class/fc_host/host2 /sys/class/scsi_host/host2 Error: No fcp devices found. I also see in the doc a lsluns command, but a't find it on my system ? Do you have any idea on how to solve this problem ? Thank you for your help. Best Regads Pierre-François Prot |
