NetBackup Appliance 2.7.3 / 3.0 Hotfix - Suppress BBU non-operational alert during relearn cycle



Suppress the BBU non-operational alert during the relearn cycle for Appliance release 2.7.3 and 3.0


When the relearn cycle starts for the Battery Backup Unit (BBU), users receive emailed alerts mentioning that the battery is non-operational. The BBU is temporarily non-operational but returns to functionality after the cycle has completed. Thus, the event is non-actionable or does not require attention. Therefore it is unnecessary to notify users via an emailed alert.

Error Message

The BBU is not operational during relearn cycle. 

UMI code: V-475-102-1021.


The non-operational alert is generated when the BBU is in relearn or maintenance mode.


The hot-fix suppresses the sending of the alert for BBU non-operational status, to prevent users from receiving unnecessary emails. Once installed, the event that trigger the described codes will be monitored and reported, but the emailed alerts will not be sent.
