All, I'm running SuSE 8.1 under z/VM 4.4 on a z800.
I'm trying to attach to some SCSI disk via zFCP. I've tried both a McData 4500 and a Brocade 3200 switch. I've checked the GBIC's and the cables, and all are good. When I vary the FCP chpid online, I can see the transmit lights on the port on the FICON card in the z800 flash yellow a few times, then they go green blinking, which is the usual status when there is no device plugged in to the port. The CHPID and the FCP devices all come online and look fine from VM. When I load the zFCP driver, I see these messages: debug: zfcp_req0x1000: new level 3 debug: zfcp_erp0x1000: new level 6 Jun 24 10:36:26 czlnx16 kernel: zfcp: zfcp_module_init: driver version 0x3003c Jun 24 10:36:26 czlnx16 kernel: debug: zfcp_lock: new level 4 Jun 24 10:36:26 czlnx16 kernel: debug: zfcp_req0x1000: new level 6 Jun 24 10:36:26 czlnx16 kernel: debug: zfcp_req0x1000: new level 3 Jun 24 10:36:26 czlnx16 kernel: debug: zfcp_erp0x1000: new level 6 zfcp: ERP: zfcp_erp_adapter_strategy: Waiting to allow the adapter with devno 0x 1000 to recover itself Jun 24 10:36:27 czlnx16 kernel: zfcp: ERP: zfcp_erp_adapter_strategy: Waiting to allow the adapter with devno 0x1000 to recover itself scsi: limiting sg entries to 256 Jun 24 10:36:35 czlnx16 kernel: scsi: limiting sg entries to 256 scsi0 : zfcp Jun 24 10:36:35 czlnx16 kernel: scsi0 : zfcp Obviously, the part about ERP waiting for the adapter to recover itself is not good. I looked at the driver a little, and this is definitely a situation where it thinks the card is not responding properly. The /proc/scsi/zfcp structure looks good. The usual directories and status files are built properly when the driver is loaded. There is lots of information in there, but where would I start troubleshooting? Are there any specific 'magic fields' that might contain codes that would help in diagnosing this? My gut feel is that the FCP/FICON card is not logging in to the switch properly, but I don't see any helpful status from the switch software. Anyone with any ideas?
