Event Code: 0e35d519 - 2," Controller operation degraded."

People,

Can anyone please assist me on this matter ? 

I've just received this error email from the HP agent on the server PRODBackup01, but not sure if this is the problem in the server HBA or in the faulty Storage Array itself ?

The system has detected the following event:

SNMP Trap:       16028

Date time:       08/19/2015  11:20:08 PM
Computer:        PRODBackup01.domain.com
Source:          Storage Agents
Type:            Informational
Category:        (4)

Description:
A 'Fibre Channel Host Controller Status Change' trap signifies that the agent has detected a change in the status of a Fibre Channel Host Controller.

Details:
Controller Slot # 3
Model 35
Host Controller World Wide Name '20000000C9F469F2'

and this is from the Storage Array email alert:

An alarm has occurred on HP P6000 Array System: PRODEVA6300 WWN: 5001-4380-1139-55D0

Alarm type: Hardware condition change

Alarm description: Event Code: 0e35d519 - 2," Controller operation degraded.");

Rebooting the server and reconnecting/reseating the Fibre connection does not help.

Thanks in advance.
