Performing a Readiness Check
Before you can initiate split mode on a system, the system must pass a readiness check. The readiness check verifies that your system meets the prerequisites for the Active Upgrade process. For example, the readiness check ensures that:
•The system is currently running in duplex mode.
•The disks you selected as system disks are present and are mirrored with RDR.
•The system contains two properly configured VTM adapters.
•The embedded Ethernet PCI adapters in your system are configured into Ethernet teams, and each team contains at least one adapter from each physical enclosure.
•The application services you specified for control are currently running, and can be stopped when necessary.
•The executable file for any custom action is present on the system and ready to run.
To perform a readiness test, do one of the following:
•Click Next on the Upgrade Summary page (if you are using a configuration file).
•Click Active Upgrade on the navigation bar (the readiness test starts automatically if you have recently opened or changed your configuration).
•Click Retry on the Active Upgrade page.
