The virtual keyswitch can be used to run full POST diagnostics without having to
modify the aforementioned properties. The standard system reset protocol bypasses
POST completely unless the virtual keyswitch or ILOM properties are set as follows:
If /SYS keyswitch_state is set to diag, the system runs POST at the next reset
using the following preset values of diagnostic properties:
■ /HOST/diag level=max
■ /HOST/diag mode=max
■ /HOST/diag verbosity=max
to provide thorough fault coverage. Setting /SYS keyswitch_state=diag
overrides the values of diagnostic properties but does not change them, setting the
keyswitch_state back to normal allows the system to resume using the /HOST/diag
property values
.
For instructions on automatic system recovery (ASR), see “Enabling and Disabling
Automatic System Recovery” on page 42 .
Automatic System Recovery User Commands
ILOM commands are available for obtaining ASR status information and for
manually unconfiguring or reconfiguring system devices. For more information, see:
■ “Unconfiguring and Reconfiguring Devices” on page 44
■ “To Reconfigure a Device Manually” on page 45

Enabling and Disabling Automatic System
Recovery
The automatic system recovery (ASR) feature is not activated until you enable it.
Enabling ASR requires changing configuration variables in ILOM as well as in
OpenBoot firmware.
