Dual Redundant BIOS
To ensure resilience in the event of a BIOS failure, appliances are equipped with dual redundant BIOS
images.
If an appliance encounters a BIOS failure, it boots up from a recovery, read-only BIOS image that enables
full functionality of the appliance.
These notifications are shown in the event of a BIOS failure:
n
The appliance's Alert LED on the front panel blinks red.
n
The
Gaia Portal
>
Maintenance
>
Hardware Health
page shows that the BIOS sensor is
Invalid
and
its status is
Off
.
Example (from a QLS800 appliance):
n
An SNMP trap message is sent (if the
biosFailure
trap was configured in the
Gaia Portal
or
Gaia
Clish
).
Example:
To recover from a BIOS failure, see
or contact
.
The appliance is fully functional until the BIOS recovery is completed.
Note that it can take a few minutes for it to boot in BIOS recovery mode.
