Sun Fire T1000 Server Service Manual • January 2006

The /var/adm directory contains several message files. The most recent messages
are in the /var/adm/messages file. After a period of time (usually every ten days),
a new messages file is automatically created. The original contents of the
messages

file are rotated to a file named messages.1. Over a period of time, the

messages are further rotated to messages.2 and messages.3, and then deleted.

1. Log in as superuser.

Managing System Components with
Automatic System Recovery Commands

The Automatic System Recovery (ASR) feature enables the server to automatically
configure failed components out of operation until they can be replaced. In the Sun
Fire T2000 server, the following components managed by the ASR feature:

UltraSPARC T1 processor strands

Memory DIMMs

I/O bus

The database that contains the list of disabled components is called the ASR blacklist
(asr-db).

In most cases, POST and ALOM automatically manage the disabling of faulty
components. When the faulty FRU is replaced, it must be manually enabled.

Example: A component appears faulty and is automatically disabled. The problem is
due to a loose connector, and no FRU replacement is required to fix the problem.
ALOM, which would normally detect a FRU replacement and enable the FRU, does
not do so. In this case, after the loose cable is reseated, the disabled component must
be manually enabled.
