B CLI Command Updates This chapter reflects new and updated commands that are available for use with Dell's PowerVault Modular Disk Series of storage arrays. NOTE: Not all commands are necessarily valid with all storage arrays - some commands are specific to certain platforms. CAUTION: Script commands are capable of changing the configuration and may cause loss of data if not used correctly. Command operations are performed as soon as you run the commands. Before using the script commands, ensure that you have backed up all data, and have saved the current configuration so that you can reinstall it if the changes do not work. New Commands The following commands have been added to this guide to reflect the additional functionality available in the PowerVault MD3600f series of storage arrays. Note that these commands are valid only with Fibre Channel storage arrays. • Activate Remote Replication Feature • Check Remote Replication Status • Create Remote Replication • Deactivate Remote Replication • Diagnose Remote Replication • Re-create Remote Replication Repository Virtual Disk • Remove Remote Replication • Resume Remote Replication • Set Remote Replication • Show Remote Replication Virtual Disk Candidates • Show Remote Replication Virtual Disk Synchronization Progress • Start Remote Replication Synchronization • Suspend Remote Replication CLI Command Updates 319
