I originally hijacked a year-old thread that was only vaguely similar (it mentioned V440's) but a kind forum moderator split my post away to let it stand on its own merits.
any how ...
we have two old Sun Fire V440 . And I recognized that two of the power supplies are failing after they have been put in the systems. They don't fail immediately. I see the message:
PSU @ PS0 fan is operating below its normal threshold.
We have considered replacing the fans in the PS, but it's not so easy to find a FAN with equal specs.
Is there a command to show the RPMs of the PS fans?
showenvironment only shows the RPM of the system fans.
