WARNING
The red LED on BMC module is used for the enclosure alarm. When the LED is solid
on, the alarm is enabled by inband SAS. When the alarm is enabled only by BMC, the
LED is blinking. When the alarm is enabled by both of BMC and inband SAS, the LED is
blinking too.
When the LED is off, the alarm is disabled by both of BMC and inband SAS. The
"REQUEST FAILURE" and “REQUEST WARNING” for Enclosure are defined in the bit1,
byte3 and bit0, byte3 of the "Enclosure control element" in the SES specification.
Setting either bit can enable the enclosure alarm. Clearing both bits disables the
enclosure alarm. We use the software package "sg3_utils" on Linux for example, and
have a SAS HBA and a cable to connect your host with the expander.
