Hello,
Posting this to get feedback on one of the features that IBM would need to implement and is called "Virtual System Attention Indicator".
*What is a System Attention Indicator ( SAI )* : When an error happens in the system, usually, it is isolated to a part to be replaced and the LED for that faulty part would be turned on.
However, in some cases, it may not be possible to isolate the issue to a particular part. In those cases, IBM systems turn on Amber LED that is mostly at the front of the system and is called "System Attention Indicator".
So, it means, there is some issue in the system and that demands service events to be examined to isolate the part.
Such errors can be detected either by Platform management functionality, BMC; or can be detected by the upper layer partitions. When we turn on the System Attention Indicator, it would be useful to say why it is turned on. As in, is it turned on due to an error seen by BMC or is it due to an error seen by the partition.
If BMC encounters an error that falls under SAI, then BMC will set a virtual SAI, which is nothing but a software setting indicating so and is called "Platform Service Attention".
Similarly, if a partition encounters an error, then a virtual SAI will be set and is called "Partition Service Attention".
So, the Physical SAI LED will be turned on if either of these virtual SAs are on.
Admins should be able to clear these software settings and that would result in clearing the real SAI LED under the cover.
As an addition, Admins can say and would chose to turn off the real SAI LED. In that case, both the virtual SA would be turned off as well.
Looking for advice on how best this can be represented in Redfish.
Thank you,
!! Vishwa !!
