I have two disk arrays dual mounted on a 280 and a V880

The disks are configured ok and work on the v880 fine, now to add the
second host to the diskset.

My understanding is that the to add another host to the diskset c?t?d? must
match on both boxes, as well as device major and minor numbers.

Currently the arrays are c2t0d?? and c3t0d?? on the working host in the
diskset(v880).
On the 280 they appear as c3t0d?? and c5t0d??/. I deleted the
/dev/dsk/c5???? and /dev/rdsk/c5???? on the 280

I cannot do a reconfigure reboot as the machines have different architecture
and wont map the drives equivilantly on a reconfigure reboot.

I then linked the correct device to c2t0d?? from ../../devices to both dsk
and rdsk.

Then it was suggested to me that I needed to make sure that the second arg
in the /etc/path_to_inst had to match on both boxes to get the major and
minor numbers the same.

for example

"/pci@8,600000/pci@1/scsi@4/sd@0,0" 350 "sd"



The 350 above was 110, but the same device on the v880 is 350. So I changed
for all disks and rebooted.

The array disks did not appear when I type format on the 280.

Is this the correct approach to make device numbers the same on both boxes
when the boxes are different hardware?

(The aim here is to get 280 onto the same diskset as the 880)
