manually clear certain types of faults without a FRU replacement or if ALOM was
unable to automatically detect the FRU replacement. ALOM does not automatically
detect hard drive replacement.
Persistent environmental faults can automatically recover. A temperature that is
exceeding a threshold may return to normal limits. An unplugged a power supply
can be plugged in and so on. Recovery of environmental faults is automatically
detected. Recovery events are reported using one of two forms:
fru at location is OK.
sensor at location is within normal range.
Environmental faults can be repaired through removal and replacement of the faulty
FRU. FRU removal is automatically detected by the environmental monitoring and
all faults associated with the removed FRU are cleared. The message for that case,
and the alert sent for all FRU removals is:
fru at location has been removed.
There is no ALOM command to manually repair an environmental fault.
ALOM does not handle hard drive faults. Use the Solaris message files to view hard
drive faults. See
“Collecting Information From Solaris OS Files and Commands” on
page 39 .
Running ALOM Service-Related Commands
This section describes the ALOM commands that are commonly used for service-
related activities.
Connecting to ALOM
Before you can run ALOM commands, you must connect to the ALOM. There are
several ways to connect to the system controller:
■ Connect an ASCII terminal directly to the serial management port.
■ Use the telnet command to connect to ALOM through an Ethernet connection
on the network management port.
■ Connect an external modem to the network management port and dial-in to the
modem.
Note – Refer to the Sun Fire T1000 Server Advanced Lights Out Manager (ALOM)
Guide for instructions on configuring and connecting to ALOM.
