4.5.3 Validation of the State and Health of the System

The validation framework runs different tests under certain conditions, such as on first boot after recovery of an Oracle Exadata Storage Server using the rescue and recovery functionality of the CELLBOOT USB flash drive, or when patching an Oracle Exadata Storage Server.

Validation framework is a set of validation tests that run at boot time at the rc.local level. The logs for the tests are available in the /var/log/cellos/validations directory.

Health check validations are a set of quick health checks on the system on each boot, such as basic health of the disks, and report the status. If a validation fails, then you should examine the log file for the cause as it may indicate potential problem requiring attention.

Automatic patch rollback occurs if one or more validation checks fail after patch application. Refer to the documentation for the specific patch.

Check for any failures reported in the /var/log/cellos/vldrun.first_boot.log file after the first boot configuration. For all subsequent boots, the /var/log/cellos/validations.log file contains information about failed validations. For each failed validation, perform the following procedure:

1. Look for /var/log/cellos/validations/failed_validation_name.SuggestedRemedy file. The file exists only if the validation process has identified some corrective action. Follow the suggestions in the file to correct the cause of the failure.

2. If the SuggestedRemedy file does not exist, then examine the log file for the failed validation in /var/log/cellos/validations to track down the cause, and correct it as needed.
