I am using FreeBSD as a fibre channel target. The initiator is a mac, connected with a point to point connection. I wish to use multipathing. I have a QLogic QLE2462 card, and I have recompiled the kernel to enable target mode support. It works, but I can't get multipathing to work. The mac sees two LUNs and connects to both. My understanding is that multipathing should "just work" on the mac side, if what the mac calls "Logical Unit Unique ID" is the same for every path. I believe that the "Logical Unit Unique ID" is the SCSI INQUIRY VPD page 0x80 data. So option "-S" in ctladm(8). But perhaps I am mistaken and it is the device id, so option "-d" in ctladm(8). To cover both cases, I have this /etc/ctl.conf configuration: lun fibre-channel { backend block device-id "FC Disk AAAA0000ZZZ01" serial "AAAA0000ZZZ01" option vendor "MGK" option product "FC Disk" path /dev/zvol/tank1/export/fc } target naa.2100001b321cd5b6 { auth-group no-authentication port isp0 port isp1 lun 0 fibre-channel } On the mac side I see the vendor and product (really only added them there for debugging), but I certainly do not see the serial number. emerald:aram$ sudo mpioutil list Alias Vendor Product LUN Identifier Algorithm 1 No Alias MGK FC Disk Least Bytes 2 No Alias MGK FC Disk Least Bytes emerald:aram$ The "LUN Identifier" is blank. Comparing the output with output from people who have this working with Solaris+mac (instead of FreeBSD) I see that there should only be one entry there if multipath is working, and the "LUN Identifier" should not be blank. The only other debugging information the mac provides is the "system report", which in my case says: Capacity: 912,68 GB (912.680.550.400 bytes) LUN Address: 00:00:00:00:00:00:00:00 Manufacturer: MGK Model: FC Disk Revision: 1 ALUA Support: Implicit Logical Unit Access State: Active Optimized Load Balancing Algorithm: Least Bytes Removable Media: No Detachable Drive: No BSD Name: disk2 Partition Map Type: Unknown A good one should be: Capacity: 8 TB (7,999,447,891,968 bytes) LUN Address: 00:00:00:00:00:00:00:00 Logical Unit Unique ID: 0x600A0B80002682A8000067D95897A544 Manufacturer: SUN Model: CSM200_R Revision: 760 ALUA Support: Unsupported Logical Unit Access State: Active Optimized Load Balancing Algorithm: Least Bytes Removable Media: Yes Detachable Drive: No BSD Name: disk6 Partition Map Type: GPT (GUID Partition Table) S.M.A.R.T. status: Not Supported Notice that I am missing the "Logical Unit Unique ID" while the working configuration displays it. Am I doing something wrong here? Why doesn't the serial number and/or the device-id I specified in ctl.conf propagate to the initiator? Unfortunately the mac really can't provide any more debugging information than that. Unless I use DTrace, but without source it's pretty difficult. On the FreeBSD side I see this type of output: ctlfe_onoffline: isp0 current WWNN 0x2000001b321cd5b6 ctlfe_onoffline: isp0 current WWPN 0x2100001b321cd5b6 isp0: Setting Channel 0 wwns to 0x2100001b321cd5b6 0x2100001b321cd5b6 ctlfe_onoffline: isp0 new WWNN 0x2100001b321cd5b6 ctlfe_onoffline: isp0 new WWPN 0x2100001b321cd5b6 ctlfe_onoffline: isp0 (path id 6) target role enable succeeded ctlfe_onoffline: isp1 current WWNN 0x2000001b323cd5b6 ctlfe_onoffline: isp1 current WWPN 0x2101001b323cd5b6 isp1: Setting Channel 0 wwns to 0x2100001b321cd5b6 0x2101001b323cd5b6 ctlfe_onoffline: isp1 new WWNN 0x2100001b321cd5b6 ctlfe_onoffline: isp1 new WWPN 0x2101001b323cd5b6 ctlfe_onoffline: isp1 (path id 7) target role enable succeeded ctlfeasync: WWPN 0x2802000155535323 port 0x000001 path 6 target 0 arrived ctlfeasync: WWPN 0x2801000155535323 port 0x000001 path 7 target 0 arrived But, as I have never done this before, I don't know if that looks correct or not. I don't know if "path 6" and "path 7" there should be the same or not. I can enable more debugging information on the FreeBSD side, but at the moment I don't know what to look for. Just for reference, I also tried this config file, and it made no difference, I get the same behavior with it: lun fibre-channel { backend block device-id "FC Disk AAAA0000ZZZ01" serial "AAAA0000ZZZ01" option vendor "MGK" option product "FC Disk" path /dev/zvol/tank1/export/fc } target naa.2100001b321cd5b6 { auth-group no-authentication port isp0 lun 0 fibre-channel } target naa.2101001b323cd5b6 { auth-group no-authentication port isp1 lun 0 fibre-channel } Thoughts?
