Domain Resource Assignment - Sun Microsystems Sun SPARC Enterprise M3000 Administration Manual

Note – Change the cpumode from auto to compatible for any domain that has or
is expected to have a mix of processor types. If you leave the domain in auto mode
and all the SPARC64 VI processors later fail, the OS will see only the SPARC64 VII
processors – because the failed SPARC64 VI processors will have been degraded –
and it will reboot the domain in SPARC64 VII Enhanced Mode. You will be able to
use DR to delete the bad SPARC64 VI boards so you can remove them. But you will
not be able to use DR to add replacement or repaired SPARC64 VI boards until you
change the domain from SPARC64 VII Enhanced Mode to SPARC64 VI Compatible
mode, which requires a reboot.
Setting cpumode to compatible in advance enables you to avoid possible failure of
a later DR add operation and one or more reboots.
The SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers XSCF User's Guide
contains the above information, as well as additional detailed instructions.
