Dell PowerVault MD3420 - Manual (Page 96)

warning will be triggered when the capacity of a replication repository virtual disk reaches 75 percent of
capacity (warningThresholdPercent=).
create asyncRemoteReplicationGroup userLabel="RRG-001"
remoteStorageArrayName="Remote_SS_A101" interfaceType=iSCSI
remotePassword="123Dell321" warningThresholdPercent=75;
Adding Primary Virtual Disk To Remote Replication Group
The add virtualDisk command adds a primary virtual disk to a remote replication group. This
command is valid only on the local storage array that contains the remote replication group to which you
want to add the primary virtual disk. To add the secondary virtual disk on the remote storage array to the
remote replication group, use the establish asyncRemoteReplication virtualDisk command.
You have two options for specifying a repository virtual disk when using this command: you can either
specify an existing repository virtual disk or create a new one when running the command.
To add a virtual disk named employeeBackfilData to the Remote_SS_A101 group you created using an
existing repository virtual disk named rep_VD_404:
add virtualDisk="employeeBackfilData"
asyncRemoteReplicationGroup="Remote_SS_A101"
repositoryVirtualDisk="rep_VD_404";
To add the same virtual disk to the same replication, but create a new 10GB repository virtual disk from
an existing disk group named DG_09:
add virtualDisk="employeeBackfilData"
asyncRemoteReplicationGroup="Remote_SS_A101"
repositoryVirtualDisk=DG_09 capacity=10GB;
You can substitute a disk pool name for the disk group name, if creating the repository virtual disk from
disk pool space.
Changing Remote Replication Group Settings
The set asyncRemoteReplicationGroup command lets you change settings for an existing
replication group.
The following parameters set synchronization and warning threshold values for the replication group.
Changing the synchronization settings affects the synchronization operations of all replicated pairs within
the remote replication group.
• syncInterval
• warningSyncThreshold
• warningRecoveryThreshold
• warningThresholdPercent
The following parameters allow you to change (or force) the primary/secondary role of a replication
group, or whether or not to perform a synchronization before changing primary/secondary roles.
• role
• force
• nosync
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.
