Re: zfcp questions
Phil -- I don't immediately see anything wrong with your adapter config file. I would recommend using the scripts included in the S390 Tools package. In particular, ... /sbin/zfcp_host_configure 0.0.0800 1 /sbin/zfcp_disk_configure 0l0.0800 0x597208239950 0x000e 1 The trailing 1 means online in both cases. The latter statement, of course, repeats per disk. You may need to take everything back down and then up again. (Bring down the disks, one at a time, even if they are not actually up, then bring down the adapter, then again execute the sequence to get them all online.) In SLES 9, you had to restamp 'mkinitrd' (and then also run 'zipl'). I have seen it go both ways with SLES 10: Most often you don't have to redo 'mkinitrd' and 'zipl', but other times it seems like you have to do them or the disks are not present after reboot. -- Rick; On Tue, Jun 8, 2010 at 13:29, Philip Tully tull...@optonline.net wrote: Hello, I am in the beginning to implement FCP disk connections on a series of linux machines running SLES 10 sp2+, during startup I receive the following series of messages: Configuring device 0.0.0800 scsi0 : zfcp 09:24:36 zfcp: The adapter 0.0.0800 reported the following characteristics: WWNN 0x5005076400caa584, WWPN 0xc05076efed800400, S_ID 0x00ab004f, adapter version 0x4, LIC version 0x2b, FC link speed 4 Gb/s zfcp: Switched fabric fibrechannel network detected at adapter 0.0.0800.

Re: zfcp questions
IIRC, on SLES 10 that message No configuration file for adapter 0.0.0800' is from the initrd doing zfcp_disk_configure 0.0.0800 0x597208239950 0x000e 1 to put the LUN online. mkinitrd didn't copy the unneeded file /etc/sysconfig/hardware/hwcfg-zfcp-bus-ccw-0.0.0800 into the initrd and zfcp_disk_configure issues that message when it doesn't find an existing /etc/sysconfig/hardware/hwcfg-zfcp-bus-ccw-0.0.0800 in the initrd to update as is its wont when it puts the LUN online. So that message is expected and harmless.
