Here's the output of ofpath and ofpathname for /dev/sda2 on the my Mac mini (10,1): ``` root@mac-mini:~# ofpath /dev/sda2 /pci@f4000000/ata-6@d/@0:2 root@mac-mini:~# ofpathname /dev/sda2 /usr/sbin/ofpathname: line 812: warning: command substitution: ignored null byte in input /pci@f4000000/ata-6@d/scsi@0/sd@0,0So here, ofpathname gets confused by the fact that Linux shows ATA devices as scsi (which is a Linux'ism). ofpath has workarounds to deal with that which should probably be ported over.Also interesting, it looks like ofpathname cannot even give a "correct" result for an IBM machine, at least not for my p5 520Q: ``` root@p5-520q:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 136.7G 0 disk ├─sda1 8:1 0 7M 0 part ├─sda2 8:2 0 131.1G 0 part ├─sda3 8:3 0 1K 0 part └─sda5 8:5 0 5.6G 0 part sr0 11:0 1 1024M 0 rom root@p5-520q:~# ofpath /dev/sda1 /pci@800000020000003/pci@2,4/pci1069,b166@1/scsi@0/@3:1 root@p5-520q:~# ofpathname /dev/sda1 /pci@800000020000003/pci@2,4/pci1069,b166@1/scsi@0/sd@3,0 root@p5-520q:~# ofpath /dev/sda2 /pci@800000020000003/pci@2,4/pci1069,b166@1/scsi@0/@3:2 root@p5-520q:~# ofpathname /dev/sda2 /pci@800000020000003/pci@2,4/pci1069,b166@1/scsi@0/sd@3,0 ``` Please notice that ofpathname returns the same result for two different partitions. :-/Ouch. I think ofpathname is still maintained by some of our IBM guys isn't it ? Might be worth digging there (or fixing it up !). Nathan, do you know anything about this ?I haven't seen this before. I don't have access to a Mac to re-create what you're seeing above, if you can send me the output from running the script with 'set -x' at the top I will take a look. You could also do this for the command above that produces the waning on line 812.
I just ran ofpathname with set -x on my 11,2 Power Mac G5 and 10,1 Mac mini (results are in the attached compressed text file). I can do the same for my p5 520Q tomorrow in the morning.
