Snap EDR Usage
The Snap Enterprise Data Replicator software distribution comes preinstalled on the
SnapScale but must first be installed in SnapExtensions and then configured before it's
available for use. It operates under the cluster management name (in the style of
<
clustername
>–mgt) and the Management IP address.
All other Snap EDR installations (including another machine running as the Management
Console that the server registers to, other Agents that register to a Snap EDR Management
Console running on the server, or other Agents replicating to/from the server) need to be able
to resolve the SnapScale cluster name to its IP address in order to interoperate properly with
the cluster. This can be accomplished via a DNS host record, local hosts file entries, or other
name resolution services in the environment.
When installing EDR to the cluster for the first time, it installs to all nodes and runs on
whichever node currently serves as the Management node. When adding a node to an existing
cluster with Snap EDR installed, it is automatically installed on that node.
Configuring Snap EDR
To configure the cluster as a Snap EDR Management Console or an Agent:
1.
Click the
SnapExtensions icon
located in the upper right corner of the Web
Management Interface.
2.
If necessary, install the
software package
:
a.
Run the
installation routine
from SnapExtensions.
SnapExtensions displays a Snap EDR link and the status
Not Installed
.
b.
Click the
Snap EDR link
and confirm the installation.
Wait for the installation to complete. The
SnapExtensions
page then displays the
Snap EDR Configuration
link.
3.
Click the
link
to launch the
Management Console/Agent
configuration page.
4.
Select either
Configure as the Management Console
or
Configure as the Agent
.
NOTE: If you are configuring a cluster as an Agent, you must provide the server name (for a
SnapServer) or cluster management name (for a SnapScale) of the Management
Console. The cluster must be able to resolve the Management Console server name to
the correct IP address.
5.
Once the cluster is configured, select the following
options
from the page that appears:
