Debugging and troubleshooting any data-center issue involves reviewing multiple log file from different sources. Tracking an issue across multiple log files, whether manually of through a third-party log file aggregator, depends upon accurate timestamp information. Ensure that the various components that make up the vSphere environment use the same NTP time source and time zone off set. Locate these settings in PowerVault Manager under Settings > System > Date and Time.
