10.7 Setting Automatic Replacement of Failed CPU Cores


10.7 Setting Automatic Replacement of Failed CPU Cores
The SPARC M12/M10 can operate systems continuously without reducing CPU resources by using the CPU automatic replacement function to automatically assign another CPU core even if some CPU core fails.
The CPU automatic replacement function is enabled/disabled based on the automatic replacement policy of the ldmd service specified by the svccfg command of Oracle Solaris. The default is enabled.
If the automatic replacement policy is enabled, the failed CPU core that was automatically replaced is controlled so as not to be assigned to a logical domain after that. If the failed CPU core was not automatically replaced, the CPU core remains to be assigned to a logical domain.
If the automatic replacement policy is disabled, then the failed CPU core is not replaced.
For the procedures to change the automatic replacement policy, see "10.7.2 Method of Changing the Automatic Replacement Policy."
