Verify and Synchronize a Cluster

Use the Verify and Synchronize task to validate the cluster configuration, reconfiguration, or changes and commit them to the cluster by updating all nodes with the same view of the configuration.

Verify and synchronize your cluster configuration after changes are made within a cluster. Those changes include, for example, changes to the hardware operating system, node configuration, or cluster configuration.

Attention: Synchronizing a cluster might delete or alter information in the cluster. Save a snapshot of the cluster before you synchronize changes.

Fields

Action to perform
Provides a list of options for verifying and synchronizing a cluster.
Verify only
Runs only the verification process. When this option is selected, only the Force synchronization if verification fails option is disabled.
Synchronize only
Runs only the synchronization process. When this option is selected, all of the other options are disabled.
Verify and Synchronize
Runs the verification and synchronization processes. When this option is selected, all of the other options are enabled. If the verification process completes successfully, by default, the synchronization process runs. You can use the Force synchronization if verification fails with the Verify and Synchronize option.
Verify
Provides a list of verification options.
Note: If you changed the operating system configuration on one or more of the nodes in your configuration, select the Entire configuration option.
Entire configuration
By default, runs a complete check of the topology and resources of a configuration.
Unsynchronized changes only
Runs verification checks on only the changes which have taken place in the ODM files since the time of the last verification operation.
Correct errors found during verification
Select an option for correcting verification errors.
No
By default, verification errors are reported but are not corrected.
Yes
Prompts you to correct common configuration issues before starting cluster services.
Force synchronization if verification fails
Select Yes or No from the menu.
No
By default, if the verification process returns errors, the synchronization process does not run.
Yes
Forces a synchronization process regardless of the results of the verification process.
Attention: This option is not recommended. If you must use this option, ensure that you understand the effects of these cluster configuration changes.
Log file to store verification output
Specifies the log file name that is used for storing the verification output. By default, the output is stored in the clutils.log file.
Terminate verification after this many errors
Sets a limit for the number of errors that can occur before the program ends. The default is 10. You can change this value by entering a new value ranging from 0 to x, where x is a whole number.
Verification methods to run
Provides a list of verification options to run.
Pre-installed only
By default, runs only preinstalled verification methods.
Custom only
Runs only the custom verification methods.
Pre-installed and custom
Runs both the preinstalled and custom verification methods.
Custom verification methods
Select one or more custom verification methods. By default, none are selected.
