writeOrder=(preserved | notPreserved) writeMode=(synchronous | asynchronous) NOTE: You can use the optional parameters as needed to help define your configuration. This example shows the create remoteReplication command: c:\...\smX\client>smcli 123.45.67.88 123.45.67.89 -c "create remoteReplication primary= \"Jan_04_Account\" secondary=\"Jan_04_Account_B\" remoteStorageArrayName=\"Tabor\" remotePassword=\"jdw2ga05\" syncPriority=highest writeMode=synchronous;" The command in this example creates a remote replication in which the primary virtual disk is named Jan_04_Account on the local storage array. The secondary virtual disk is named Jan_04_Account_B on the remote storage array that is named Tabor. The names used in this example are similar, but that is not a requirement for the virtual disk names in a remote replicated pair. In this example, the remote storage array has a password that you must enter when making any change to the storage array configuration. Creating a remote replicated pair is a significant change to a storage array configuration. Setting the write mode to synchronous and the synchronization priority to highest means that host write requests are written to the primary virtual disk and then immediately copied to the secondary virtual disk. These actions help to make sure that the data on the secondary virtual disk is as accurate a copy of the data on the primary virtual disk as possible. The highest synchronization priority does, however, use more system resources, which can reduce system performance. This example shows how to use the command in a script file: create remoteReplication primary="Jan_04_Account" secondary="Jan_04_Account_B" remoteStorageArrayName="Tabor" remotePassword="jdw2ga05" syncPriority=highest writeMode=synchronous; After you have created a remote replication, you can see the progress of data synchronization between the primary virtual disk and the secondary virtual disk by running the show remoteReplication synchronizationProgress command. This command shows the progress as a percentage of data synchronization that has completed. Changing Remote Replication Settings The set remoteReplication command lets you change the property settings for a remote replicated pair. Use this command to change these property settings: • The virtual disk role (either primary or secondary) • The synchronization priority • The write order • The write mode You can apply the changes to one or several remote replicated pairs by using this command. Use the primary virtual disk name to identify the remote replicated pairs for which you are changing the properties. This example shows how to use the set remoteReplication command: c:\...\smX\client>smcli 123.45.67.88 123.45.67.89 -c "set remoteReplication localVirtualDisk [Jan_04_Account] syncPriority=medium writeOrder=notpreserved writeMode=asynchronous;" 74
