Device names

messing with shared disksets (using Solstice DiskSuite).
As far as I know, the two machines connected to the disk array are symmetric:
They:
* E220R's
* Have the same fibrechannel cards installed in the same slots
* Have no other cards installed elsewhere
* Have the exact same O/S version & patches (they were jumpstarted
at the same time using the same jumpstart configuration).
However, on the second machine, when connecting the cable to the disk array
and running "format", I see something like:
7. c1t5d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>
/pci at 1f,4000/scsi at 5/ssd at w220000203719ffea,0
When connecting the cable to the other fibrechannel card on that machine and
running the same command (after running 'drvconfig;disks;devlinks'), I get:
7. c3t5d0 <drive not available: reserved>
/pci at 1f,4000/SUNW,ifp at 4/ssd at w220000203719ffea,0
So a few questions come to mind:
1) Why would one adapter use scsi, while the other uses ifp?
2) Is there any way to renumber the device names so that c1tXdX
could be c2tXdX, or such? I need both of the machines to see the
array through the same major/minor numbers for the shared diskset
setup to work, AFAIK.
BTW, I am using Solaris 8 (2/02) w/ the latest patches.
