Hi

We have an E3000 running 2.6, origianlly the internal disks
were on Controller 0; later (long back) we added a SSA to
arry to it. The disks in SSA were on controller 1; later
we decided to replaced the SSA with an A1000; so connected
an A1000; disks on A1000 were on controller 2;

we copied the files from SSA to A1000; we are all
happy and retired the SSA;

At this stage we had only controller 0 [internal disks]
and controller 2 [A1000 disks]; SSA retired and
Controller 1 not be used (no more c1... disks]

Now we are in the process of upgrading the system to
solaris 2.8 [not upgrade/fresh install].

now the A1000 controller and disks are available as
c0 and internal disks as c1t?.... which is not acceptable
to use.

WE need the internal disks to come as controller - 0
and A1000 disks to come as controller 2; because of
some database software using raw devices;

I believe this can be done by adjust path_to_inst file.

how can one do this? how to controll the controller
addressing?

thanks for your time and efforts,
Durai
