Applying the Configuration
As a safety measure, changes to the storage server configuration in the SANmelody software are first queued and require explicit acknowledgement before they go into effect. You will notice that preliminary configuration changes will first cause the affected icons to temporarily change to red until the configuration changes have been applied.
To undo any series of preliminary configuration changes before committing them, close the SANmelody interface without applying. All changes will be lost and you revert to the last applied configuration.
When satisfied with the changes, click the Apply icon 
on the toolbar to apply the configuration changes and trigger the specific actions previously requested. You will receive a message confirming a successful Apply.
To make configuration changes, the storage server making the changes must be in Read/Write mode 
.
