my Blade 1500 /var/adm/messages keeps showing:
*Jan 21 20:30:17 blade1500 picld: [ID 845468 daemon.crit] SUNW_piclenvd: 'cpu' sensor temperature 96 outside safe operating limits (0...95).*
However it passes all self-tests etc and the fans seem OK.
If I idle for 30 minutes the temp drops to around 65, but just a single tap on an ssh connected session and the temp jumps up to 94/95!!
Is this issue something to be concerned with? Faulty sensor or genuine issue?
I have OBP 4.9.5 (I think)
OBP 4.9.5 is, as you can see from the bottom of the prtdiag output, 8yrs out of date. The latest for that system is OBP 4.30.4.a + POST 4.30.4.a + OBDIAG 4.30.4.a as delivered with patch
140686-02 "Hardware/PROM: Sun Blade 1500 (non Silver) Flash PROM Update"
140687-02 "Hardware/PROM: Sun Blade 1500 Silver Flash PROM Update"
The difference between the Silver and Non Silver versions are denoted (visually) by the colour of the plastic bubble where you see the Sun Logo. If it's a Silver/Grey then you have the SB 1500 Silver edition. If it's red, then you have the non-Silver edition.
Given the OBP is so far out of date I'd start there. picld interacts with the HW and there have been many fixes introduced in the OBP (firmware) that need to be applied.
You may also want to open up the unit and clean out any dust and rubbish from inside and around the fans. If we're unable to get clean airflow through the system it'll over heat quickly. Remember to follow ESD (Electrostatic Discharge) precautions so you don't destroy any hardware components.
Finally, what OS do you have installed? (uname -a). As stated above picld talks to the HW so you may also want to verify the picld patch is up to date.
If you still have issues after you've updated OBP, picld, and given the system a good clean then please raise a service request and we'll take a closer look at the hardware. It may be a sensor that's on it's way out.
Is there any way to get the flash update without a support contract? I am using a private property blade 1500 to prepare for an oracle certification exam and I am having similar troubles with the OBP.
