Managing Components with Automatic
System Recovery (ASR) 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
comments and automatically enables them when the faulty FRU is replaced. In some
situations, it is necessary to manually manage the blacklist.
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.
