Further investigation of the post log reveals the following, but still no
concrete indication as to what the problem might be:
phase cplane_isolate: CP domain cluster mask clear...

As you can see, there is no indication of a component that has FAILED and
at first glance, it might be difficult to determine where the problem lies.
The key here can be found at line 13 of the above POST log. It appears that
Address Bus 0 (abus 0) has been blacklisted, yet the bus configuration
(line 15,19) of the platform calls for the use of all 4 address buses and
both data buses. Similarly, in cases where a data bus (dbus X) has been
incorrectly blacklisted, the end result was also that a problem such as
this was encountered.
In this sample case, looking at the blacklist file for the platform
(/var/opt/SUNWssp/etc/<platform name>/blacklist) revealed that someone had
recently editted the blacklist file using hostview. The indication was as
follows:
#=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+
#Blacklist file edited by Hostview - Wed Nov  5 16:21:58 MET 2003
#=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+
To resolve this issue, remove the 'abus' or 'dbus' entry from the blacklist
file and execute the 'bringup' command again. If the intent was to actually
blacklist one of these buses, all domains MUST be down and a 'bringup -C'
must be issued to reconfigure the centerplane.
