Establish Remote Replicated Pair
Description
Use this command to complete a remote replicated pair on the remote storage array by adding a
secondary virtual disk to an existing remote replication group. Before you run this command, the remote
replication group must exist and the primary virtual disk must exist in the remote replication group. After
this command successfully completes, remote replication starts between the primary virtual disk and the
secondary virtual disk.
The two virtual disks comprising a remote replicated pair function as a single entity. Establishing a remote
replicated pair allows you to perform actions on the entire replicated pair versus the two individual virtual
disks.
Syntax
establish asyncRemoteReplication virtualDisk="secondaryVirtualDiskName"
asyncRemoteReplicationGroup="asyncRemoteReplicationGroupName"
primaryVirtualDisk="primayVirtualDiskName"
Parameters
Parameter Description
asyncRemoteReplication The name of an existing virtual disk on the remote
storage array that you want to use for the
secondary virtual disk. Enclose the virtual disk
name in double quotation marks (" ").
asyncRemoteReplicationGroup The name of an existing remote replication group
that you want to use to contain the remote
replicated pair. Enclose the remote replication
group name in double quotation marks (" ").
primaryVirtualDisk The name of an existing virtual disk on the local
storage array that you want to use for the primary
virtual disk. Enclose the virtual disk name in double
quotation marks (" ").
Notes
A remote replicated pair is comprised of two virtual disks, a primary virtual disk and a secondary virtual
disk, that contain identical copies of the same data. The replicated pair is a part of a remote replication
group, which allows the replicated pair to synchronize at the same time as any other replicated pairs
within the remote replication group.
You can use any combination of alphanumeric characters, hyphens, and underscores for the names.
Names can have a maximum of 30 characters.
When you choose the primary virtual disk and the secondary virtual disk, the secondary virtual disk must
be of equal or greater size than the primary virtual disk. The RAID level of the secondary virtual disk does
not have to be the same as the primary virtual disk.
