Oracle SPARC M8 Service Manual page 87

Unsupported CMIOU configurations include:
SPARC M7-8 server PDomain_1 containing both SPARC M7 and SPARC M8 CMIOUs.
■
There cannot be a mix of SPARC M7 and SPARC M8 CMIOUs in PDomain_1. All of the
CMIOUs in PDomain_1 must only be either SPARC M7 CMIOUs or SPARC M8 CMIOUs.
SPARC M8 CMIOUs are not supported in SPARC M7-16 servers or SPARC M7-8 servers
■
configured as one static PDomain containing up to eight CMIOUs.
SPARC M7 CMIOUs are not supported in the SPARC M8-8 server.
■
A PDomain will not power on if it contains an unsupported configuration. If the PDomain
contains an unsupported configuration, the host console will display error messages and the
server will generate an ereport alerting you to the unsupported configuration. You must fix the
unsupported configuration by either removing or disabling the offending CMIOUs before you
can power on the PDomain.
Note - If the PDomain is running and you attempt to install a CMIOU that creates an
unsupported CMIOU configuration (for example, if you install SPARC M8 CMIOU in a
SPARC M7-16 server), the PDomain will continue to run. The server will generate an ereport
alerting you to the unsupported configuration, and the new CMIOUs will not be added to the
running PDomain. You must fix the unsupported configuration by either removing or disabling
the offending CMIOUs before you can restart the PDomain.
A SPARC M7-8 server with a mixed CMIOU configuration must run a system firmware version
that supports both SPARC M8 and SPARC M7 CMIOUs. Additionally, the server's PDomain_1
containing the SPARC M8 CMIOUs must be running an Oracle Solaris version that supports
the SPARC M8 CMIOUs. For the minimum supported versions of the supported software and
firmware, refer to the SPARC M8 and SPARC M7 Servers Product
