   Article Number:     531080                                   Article Version: 3     Article Type:    Break Fix 




Data Domain,DD3300 Appliance





The Data Domain Operating System queries iDRAC (integrated Dell Remote Access Console) to determine fan and temperature statuses. When this communication is interrupted, the fan and temperature statuses cannot be reliably determined and will default to FAILED and UNAVAILABLE respectively.  This status may or may not be posted as an alert but will remain in the same state until the condition is resolved.   
    Applies to:   
    DD3300 appliance only   
    DDOS version 6.1.x   






    The issue is caused by a bug in certain versions of the iDRAC module firmware. It fails to fully provide hardware information to DDOS. As a result, DDOS assumes this hardware is either missing or in a failed state.   
    All fans show up as FAILED and all components under Temperature show as UNAVAILABLE.
