I am seeing issues where the cucsStorageControllerOperState (1.3.6.1.4.1.9.9.719.1.45.1.1.6.{#SNMPINDEX}) is "unknown" for all Controllers in the table? Is this a problem with USC / snmp? I see the same for both B-Series and C-Series systems. We are running UCS 5.0(3)N2(4.02a)

Example: Name/OID: cucsStorageControllerOperState.23753313; Value (Integer): unknown (0)

This causes "Disk array controller status" Zabbix problems for all the disks.
