additional information about components associated with hardware errors.
TABLE 5-3
Diagnostic and Operating System Recovery Parameters
Parameter Set Using Default Value Description
Host Watchdog setupsc enabled
Automatically reboots the domain when a
hardware error is detected. Also boots the
Solaris Operating System when the
OpenBoot PROM
auto-boot
parameter is
set to
true
.
Tolerate
correctable
memory errors
setupsc false
If set to
true
it allows the Solaris
Operating System to boot with memory
exhibiting correctable ECC errors.
The Solaris 10 Operating System
incorporates features that automatically
isolate faulty parts of such memory
modules, thus avoiding the need to
completely disable these modules and
increasing server availability.
If set to
false
, memory modules
exhibiting correctable ECC errors are
disabled by POST and not allowed to
participate in the Solaris domain.
reboot-on-error setenv true
Automatically reboots the domain when a
hardware error is detected. Also boots the
Solaris Operating System when the
OpenBoot PROM
auto-boot
parameter is
set to
true
.
auto-boot setenv true
Boots the Solaris Operating System after
POST runs.
error-reset-
recovery
setenv sync
Automatically reboots the server after an
XIR occurs and generates a core file that can
be used to troubleshoot the system hang.
However, be aware that sufficient disk
space must be allocated in the swap area to
hold the core file.
