How do I determine the hardware path to a disk in a fibre-attached
JBOD from the path name in Solaris 8 for a SunFire V880? By 'hardware
path' I mean the different hardware devices in the chain to the disk:
the PCI slot number in the machine, the interface on the PCI card (ie:
for the case that there are multiple channels on the same PCI HBA
card) and, if possible, the disk number in the enclosure. By 'path
name' I mean the standard Solaris scheme for the logical path of
/dev/rdsk/c8t2d0s2 or the physical path of
/devices/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w210000203715a7bd,0:c,raw.
In other words, if you can look at the physical path name I just gave
and tell me the PCI slot, channel and (if possible) the disk, that
would answer our question.
As a hint, if you look at the page,
http://developers.sun.com/solaris/articles/devicemapping.html, and
table 3, you'll see the mapping from physical path to slot in the
server for a 450. This is a partial answer to what we want, but we
want this for a V880 and we also want the information about the
channel number. |
