Chapter 2 Setting Up XSCF 2-131
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 Solaris 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.
