Dell 34XX, 38XX, 32XX, 36XX Adding Primary Virtual Disk To Remote Replication Group, SyncInterval

The create asyncRemoteReplicationGroup command creates a new, empty remote replication group on both the local storage array and the remote storage array. Each replicated pair you add to the remote replication group share the same synchronization settings, primary and secondary role, and write mode.

This command must be run on the local storage array. Remote replication group creation is initiated from the storage array that contains the virtual disks that hold the primary role in the replicate relationship. The following command create a replication group names RRG-001 on a remote iSCSI storage array named Remote_SS_A101. The remote storage array has a password of 123Dell321 (remotePassword=). A 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
