Issues Fixed in ILOM 3.0.10
Blade Fan Control Improvement (6903302)
This issue was fixed in ILOM 3.0.10.
When a Sun Blade 6000 chassis or 6048 shelf is powered on, the fan speed quickly
ramps up from minimum speed to maximum speed, then ramps down to minimum
speed. This does not allow enough time for the fans to cool the blades, so the fan
speed ramps back up again, which causes a fan speed oscillation effect.
Fix Applied in SW 3.2 (ILOM 3.0.10)
The CMM steps up the fans at most one step every 40 seconds (so there’s a slower
ramp up time), and decreases fan speeds one step every 2 minutes to allow
appropriate temperature adjustment of all blades.
