Hello --
Yesterday the "ATTENTION" light ( the middle yellow LED on the front
panel ) began flashing. This coincided two events: a failure of the
room air conditioning unit and a room power failure, which caused a hard
server reboot.
The server came up fine from the reboot, and all appears normal. The AC
unit is now functioning correctly.
The HP LED decoder tool
(http://docs.hp.com/hpux/onlinedocs/hw/rp5400/en/tools/l1/frontpanelledd
ecode_l1/index.html) reports that this light pattern indicates
"Non-critical error detected (ie. Fan failure)"
I'm assuming -- possibly incorrectly -- that this status light was
related to temperature in the room, not the reboot.
My question is two-fold:
1. Am I correct in assuming that the status light is a result of the
room temperature?
2. Should it go away automatically as the temperature decreases? If
so, I would expect it to be gone by now as this event occurred yesterday
morning. If not, is there a way to reset it?
Also, are there any HP-UX commands to interrogate the status lights in
more depth?
Can anyone shed more light on or around this topic?
I will summarize to the list.
