Symptoms

 Although HPOST doesn't FAIL any components, it exits almost immediately with a generic message such as the following:

Exitcode = 76: Unable to configure a bootable system
POST (level=16, verbose=20) execution time 0:03
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...
No minimum system left after CP domain cluster mask clear! Bailing out!

The entire POST log might look as follows:

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

#=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+

Changes

Cause

 The blacklist file has been updated to include abus or dbus.

Solution

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.

Internal Comments
This problem resulted in a Sev 1 Task for CaseID 36996496. Searching
SunSolve revealed that this problem had also been seen in at least 4 other
cases as well.
