Replication is a disaster-recovery feature that performs
asynchronous replication of block-level data from a volume in a primary
storage system to a volume in a secondary storage system.
The replication
feature creates an internal snapshot of the primary volume, and copies
changes to the data since the last replication to the secondary system
using iSCSI or FC connections. The primary volume exists in a primary pool
in the primary storage system. Replication can be completed using
either the PowerVault Manager or the CLI.
Replication
setup and verification
After storage systems are cabled for replication,
you can use the PowerVault Manager to prepare
for using the replication feature. Alternatively, you can use SSH
or telnet to access the IP address of the controller module and access
the replication feature using the CLI.
Basic information for enabling the ME4 Series Storage System controller enclosures
for replication supplements the troubleshooting procedures that follow.
Familiarize yourself
with replication content provided in the Dell PowerVault ME4 Series Series Storage System Administrator’s Guide.
For virtual replication, perform the
following steps to replicate an existing volume to a pool on the peer in
the primary system or secondary system:
Find the port address
on the secondary system:
Using the CLI, run the show ports command on the secondary system.
Verify that ports on
the secondary system can be reached from the primary system using
either of the following methods:
Run the query
peer-connection CLI command on the primary system, using
a port address obtained from the output of the show ports command.
In the PowerVault ManagerReplications topic,
select Action > Query Peer Connection.
Create a peer connection.
To create a peer connection, use the create peer-connection
CLI command or in the PowerVault ManagerReplications topic, select Action > Create Peer Connection.
Create a virtual replication
set.
To create a replication set, use the create
replication-set CLI command or in the PowerVault ManagerReplications topic, select Action
> Create Replication Set.
Replicate.
To initiate replication, use the replicate CLI command
or in the PowerVault ManagerReplications topic, select Action > Replicate.
Using the PowerVault Manager, monitor the storage system
event logs for information about enclosure-related events, and to
determine any necessary recommended actions
NOTE:These steps are
a general outline of the replication setup. Refer to the following
manuals for more information about replication setup:
See theDell PowerVault ME4 Series Series Storage System
Administrator’s Guide for procedures to set up and manage replications.
See the Dell PowerVault ME4 Series Series Storage System
CLI Guide for replication commands and syntax.
NOTE:Controller module
firmware must be compatible on all systems that are used for replication.
