replication --add --name <name> --role <source | target> --peer <ip address | hostname> [--peer_name <name>] [--peer_group_name <name>] [--replication_traffic <ip address | hostname>] [--encryption <none | aes128 | aes256>][--username <user name>]

Description

Adds a new replication link to a container on the QoreStor, for which you need to define its name, role, peer IP address/hostname , peer name, peer group name, user name on the peer system, and encryption level to apply. The peer group name is the name of the remote container’s group to replicate to/from, and this parameter is applicable only if a remote container is not present.

There are three options for encryption:

  • none,
  • aes128 (Advanced Encryption Standard) which uses128-bit cryptographic keys
  • aes256 (using 256-bit AES cryptographic keys).

If the username is a domain login (for example, domain\username), ensure that '\' characters and spaces are either escaped or in quotes.

NOTE: Make sure that the data container you intend to replicate already exists. If it does not, the following error message displays: Error: Container <container_name> does not exist.

Syntax

replication --add --name <name>
	--role <source | target>
	--peer <ip address | hostname>
	[--peer_name <name>]
	[--peer_group_name <name>]
	[--replication_traffic <ip address | hostname>]
	[--encryption <none || aes256>]
	[--username <user name>]

Where

--name                  Name of container to replicate.
--role                  Role of container.
--peer                  Peer appliance IP address/name of replication network interface(s).
--peer_name             Name of remote container to/from replicate.
--peer_group_name       Name of remote container's group to/from replicate. Only applicable if remote container is not present
--replication_traffic   IP address/name of local dedicated replication network interface(s).
--encryption            Type of encryption to use on the wire.
--username              Username on peer system.

Result

replication --update --name <name> --role <source | target> [--peer <ip address | hostname>] [--encryption <none | aes128 | aes256>] [--username <user name>]

Description

Updates an existing replication link to a container in a QoreStor and allows you to change the corresponding role, peer IP address or host name, the encryption being used, and user name based on the QoreStor CLI command options you specify.

Syntax

replication --update --name <name>
	--role <source | target>
	[--peer <ip address | hostname>]
	[--replication_traffic <ip address | hostname>]
	[--encryption <none || aes256>]
	[--username <user name>]

Where

--name                  Name of the replication container to update.
--role                  Current replication role of container.
--peer                  Peer appliance IP address/name of replication network interface.
--replication_traffic   IP address/name of dedicated replication network interface.
--encryption            Type of encryption to use on the wire.
--username              Username on peer system.

Result

NOTE: If you attempt to update a container that already has replication enabled, this displays the following message:

Replication on backup is enabled and cannot be updated, please stop it first.

When replication is enabled on the container, you must first disable it before you can update it. To disable replication on a container, enter the QoreStor CLI replication --stop command and define the container name and role:

replication --stop --name <name> --role <source | target>

NOTE: For more information about disabling replication, see replication --stop --name <name> --role <source | target>.

Disables replication on a container:

replication --stop --name backup --role source

replication --delete --name <name> --role <source | target> [--force]

Description

Deletes an existing replication link to a container in a QoreStor.

NOTE: It is recommended that the replication be in an INSYNC state for this operation. If replication is not in an INSYNC state, this operation can potentially take a much longer time to execute.

Syntax

replication --delete --name <name> --role <source | target> [--force]

Where

--name    Name of container.
--role    Role of container.
--force   Delete configuration even if peer container is unreachable. Replication must be stopped first even with force option.

If you attempt to delete a container that already has replication enabled, this displays the following message:

Replication on acme-59-replica is enabled and cannot be deleted, please stop it first.

NOTE: If the replication state of the link is enabled, you must use the replication --stop command to disable replication before you can delete the replication link. For more information, see replication --stop --name <name> --role <source | target>.

Deletes the existing replication link to a container.

replication --delete --name acme-59-replica --role source
 

Result

Successfully deleted replication entry.

NOTE: The QoreStor CLI --force command is optional, and this command allows you to force the deletion of an existing replication link (such as when communications between the source and target are not working). Before using the --force option, replication must be stopped with the replication --stop command. For more information, see replication --stop --name <name> --role <source | target>

replication --start --name <name> --role <source | target>

Description

Starts the replication process on an existing replication link to a container in a QoreStor.

Syntax

replication --start --name <name> --role <source | target>

Where

--name   Name of container.
--role   Role of container.

Result

Replication configuration updated successfully.
