A previously reported fan issue seen in NetBackup Appliances 2.5.x versions has been reported on NetBackup 5220 Appliances with JBODs running 2.6.0.x or 2.6.1. The same "Noncritical" warnings on FAN 1 and 2 are reported for the Storage shelf, and the RPMs appear to be stuck around 8k RPMs.

enclosure_1_fan_1_errorstatus CRITICAL 1 Must equal 
enclosure_1_fan_1_lowwatermark 2000 RPM

enclosure_1_fan_2_errorstatus CRITICAL 1 Must equal 
enclosure_1_fan_2_lowwatermark 2000 RPM
enclosure_1_fan_2_speed 8010 RPM
Fans run at higher speeds to compensate for higher temperatures and are stuck at high RPMs, producing a peculiar noise and raising an alert.
