BBU Error not detected

Hy!

One of the best scripts i found for monitoring ESXi Hosts without vCenter!
I’m using it on Fujitsu Servers, Hardware Option = intel.

The Script detects Disk Errors without Problems, but if an BBU needs to be replaces the Scrips returns OK??

Scriptoutput:
OK – Server: FUJITSU System BIOS: V4.6.5.3 R1.15.0 for D2939-A1x 2012-09-12

ESXi 4.1
Status = Critical
BBU on Controller 0 (Health State Not Good)

Maybe anybody can help to find an solution

cheers
