*1 Reconfigure logical domains as required. For details, see "Chapter 5 Logical Domain Configuration Example" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide. *2 Observe the installation rules to remove memory. For details, see "2.2 Checking the Memory Configuration Rules." |
