I did not receive any responses at all relating to temperature swings on SB1000's or on the XVR-100 graphics card in a SB1000. ORIGINAL POST: -------------- Sun Managers: OS: Solaris 8 with 8_Recommended_2003-02-20 patch cluster HARDWARE: SunBlade 1000 w/4Gb RAM Two questions I hope you can help me with to get one of our systems back up and running: (1) Has anyone tried one of Sun's new XVR-100 2-D graphics boards in a SunBlade 1000 successfully? Sun says they work in a Blade 2000 but won't guarantee they work in the older 1000. (2) We recently had a Creator 3D graphics board fail in a SunBlade 1000 desktop machine. On further investigation, the unit's /var/adm/messages file contains: picld[73]: [ID 402047 daemon.crit] SUNW_piclenvd: pmthr thread creation failed! and a bunch of: picld[73]: [ID 845468 daemon.crit] SUNW_piclenvd: 'cpu0' sensor temperature 90 outside safe operating limits (0...88) Looping the /usr/platform/sun4u/sbin/prtdiag -v command and grepping for CPU temps and cpu fan speeds (see below) shows that: - the CPU fan is staying at 19% speed until the CPU temperature exceeds 88 degrees C - when the die temp reaches 88 degrees the system logs the overtemp in /var/adm/messages and increases the fan speed to 100% - the CPU temp gradually falls and the fan speed is gradually reduced to 19% again - the cycle repeats itself Unfortunately, the script that we use to monitor /var/adm/messages output was not looking for "daemon.crit" so I don't know if this is a new problem or not. It seems like the ratiometric control of the fans on rising temperature is not working. I presume that this may be because of the picld "pmthr" thread dying. Has anyone else experienced this problem? If so, any suggestions on work arounds or fixes would be most welcome. Thanks - I will summarize.
