With the FCMGMT-MIB, I am able to query the VNX5100 Overall Status

with the OID of connUnitStatus.80.6.1.96.189.224.46.14.0.0.0.0.0.0.0.0, with description below:-

Overall status of the connectivity unit. The goal of this

object is to be the single poll point to check the status

of the connunit. If there is any other component that has

warning, then this should be set to warning, etc. Any of

these values may occur with any of the ConnUnitState

values.

Does anyone know if it's reliable to use such SNMP query to determine the unit health?

I mean if any component fault happens, would the status change from ok(3) to warning (4) or failed (5)?
