Table 59: Memory RAS Configuration Status Sensor – Event Trigger Offset – Next Steps
RAS configuration
enabled.
User enabled mirrored channel mode
in setup.
Informational event only.
RAS configuration
disabled.
Mirrored channel mode is disabled
(either in setup or due to unavailability
of memory at post, in which case post
error 8500 is also logged).
1. If this event is accompanied by a post error 8500, there was a problem
applying the mirroring configuration to the memory. Check for other errors
related to the memory and troubleshoot accordingly.
2. If there is no post error, mirror mode was simply disabled in BIOS setup and
this should be considered informational only.
