The dynamic tunable is used to enable or disable the MCA Error Recovery functionality. If disabled, an MCA will cause the system to initi- ate a crash dump and then a system reset (normal legacy behavior). If enabled, certain MCAs caused by transient events will be recovered and system execution resumed. The recovery action depends on the type of MCA and can include termination of a user process. Who Is Expected to Change This Tunable? System administrators can change the value of depending on the usage of the system. Restrictions on Changing MCA Error Recovery is only supported on Dual-Core Processors 9100 Series and later. On unsupported systems, MCA Error Recovery will be disabled by default and changing the tunable will not be allowed.WARNINGSAll HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed.
