HP OneView 1.0 User Guide
27.1 Basic troubleshooting techniques
HP OneView has a variety of troubleshooting tools you can use to resolve issues. By following a
combined approach of examining screens and logs, you can obtain a history of activity and the
errors encountered along the way.
• The Activity screen displays a log of all changes made on the appliance, whether user-initiated
or appliance-initiated. It is similar to an audit log, but with finer detail and it is easier to access
from the UI.
The Activity screen also provides a log of health alerts and status notifications.
• Download an audit log to help an administrator understand what security relevant actions
took place on the system.
• Create a support dump file to gather logs and other information required for debugging into
an encrypted, compressed file that you can send to your authorized support representative
for analysis.
DetailsRecommendation
About syntax errors:
• The user interface checks for syntax when you enter a value. If you make a syntax error,
an instructional message appears next to the entry. The user interface or command line
continues to display messages until you enter the correct value.
About network setup errors:
• Before applying them, the appliance verifies key network parameters like the IP address
and the fully qualified domain name (FQDN), to ensure that they have the proper format.
• After network settings are applied, the appliance performs additional validation, such as
reachability checks and host name to IP lookup. If a parameter is incorrect, the appliance
generates an alert that describes validation errors for the Network Interface Card (NIC),
and the connection between the browser and the appliance can be lost.
About reported serious errors:
• Check connectivity to the enclosure from the appliance.
• Create a support dump and contact your HP support representative.
