T2000 scsi device probe order

   Hi,

I recently upgraded the firmware of a Sunfire T2000 server to latest version.
After this I attempted to do a Solaris upgrade, however during the upgrade
fail with a message stating that the disks could not be mounted. This server
has an HBA in it and is connected to a san. When I boot the server into single
user mode from the Solaris DVD, I noticed that the logical name of the OS disk
was different to when I booted from the disk itself (from the DVD it was
c1t0d0sX and from the boot disk it was c1t0d0sX). The only way I can explain
this, is to presume that the system was originally built without the HBA and
the HBA added afterwards. I am not keen at all to do a complete rebuild of the
OS because of the connectivity to the san and the multi-pathing setup etc nor
am I keen to remove the HBA and then do the upgrade build. Is there any way
within the OBP to determine the order that the scsi devices are probed and
hence the logical device names?
