Dell PowerVault MD3260i - Manual (Page 102)

The command takes this form:
create remoteReplication primary=“primaryVirtualDiskName”
secondary=“secondaryVirtualDiskName”
(remoteStorageArrayName=“storageArrayName” |
remoteStorageArrayWwn=“wwID”) remotePassword=password
syncPriority=(highest | high | medium | low | lowest)
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 (Legacy) 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.
