EMC Secure Remote Support Gateway for Linux Release 2.24 Operations Guide
Introduction
Gateway Client servers, in a High Availability configuration, are
active peers. Each Gateway Client in the cluster manages the same set
of devices without awareness of, or contention with, the other
Gateway Clients in the cluster. There is no direct communication
between the Gateway Clients within the cluster.
If Gateways that are to be Clustered to create an HA environment are
installed in separated sites with different Party/SiteID’s, the
Party/SiteID of those additional Gateways must be added to the
cluster to permit the Gateways to be enumerated and joined to the
existing cluster.
In the High Availability configuration, the Policy Manager software
cannot be co-located on a Gateway Client server. It must be installed
on a separate server.
Synchronization of Gateway Client clusters
Gateway Client cluster device management is synchronized by the
EMC enterprise servers during polling cycles so that changes to the
configuration on one Gateway Client in the cluster are automatically
propagated to the other. When there is an addition, removal, or edit
of a device on the managed devices list for any Gateway Client in a
High Availability Gateway Cluster configuration, the EMC enterprise
sends a synchronization message to all clustered Gateway Clients.
When the other Gateway Client(s) in the cluster receives the device
management transaction information, it updates its list of managed
devices maintained on the Gateway Client. If that Gateway Client is
currently not available during a synchronization attempt, the EMC
enterprise queues the transaction. Synchronization of the Gateway
Cluster occurs upon the next successful poll message received from
the previously unavailable Gateway Client.
Installing a High
Availability Gateway
Cluster
To implement a High Availability Gateway Cluster configuration,
your EMC Global Services professional will create the cluster
relationship from the Device Management utility that is part of the
EMC enterprise application (ServiceLink).
When a cluster is created, a cluster name must be assigned. The
default name is the organization name followed by the words HA
Gateways. Other names can be assigned, but no two clusters can have
the same name.
Note: The Cluster name is limited to 64 characters.
