Hardware Status for ESXi Host - Unknown ?

[TonyJK]

Hi,

We are using IBM System x3650 M3 Server for running vSphere 5.

We find that all CIM sensors (except CPU) are shown as Unknown.  From IBM IMM, it doesn't report any system error.

We have reset and update those sensors but still get the same result.

Your advice is sought.

Have you installed the custom VIB for IBM hardware?
