/var/adm/messages
from the time leading
up to the failure.
■
Output from the LOM shell for the following system controller commands:
■
showsc -v

Automatic Diagnosis and Recovery
Overview
The diagnosis and recovery features are enabled by default on Netra 1290 servers.
This section provides an overview of how these features work.
Depending on the type of hardware errors that occur and the diagnostic controls
that are set, the system controller performs certain diagnosis and recovery steps, as
FIGURE 5-1
shows. The firmware includes an autodiagnosis (AD) engine, which detects
and diagnoses hardware errors that affect the availability of a server.
Note – Although the Netra 1290 server does not support the multiple domains that
other midrange systems support, by convention, diagnostic output provides system
status as the status for
Domain A.
