Storage Mirroring service for the new port setting to take effect.
2. You need to configure your hardware so that Storage Mirroring Recover traffic is
permitted access through the router and directed appropriately. Configure your
router identifying each Storage Mirroring Recover server, its IP address, and the
Storage Mirroring Recover and router ports. Also, note the following caveats.
● Since Storage Mirroring Recover communication occurs bidirectionally,
make sure you configure your router for both incoming and outgoing traffic for
all of your Storage Mirroring Recover servers and Storage Mirroring Recover
clients.
● Storage Mirroring Recover failover can use ICMP pings to determine if the
source server is online. If you are going to use ICMP pings and a router
between the source and target is blocking ICMP traffic, failover monitors
cannot be created or used. In this situation, you must configure your router to
allow ICMP pings between the source and target.
Since there are many types of hardware on the market, each can be configured
differently. See your hardware reference manual for instructions on setting up your
particular router.
3. Manually insert the servers, by selecting Insert, Server. Type the IP address of the
router the server is connected to and the port number the server is using for
heartbeats.
4. Once your server is inserted in the Replication Console, use the Connection
Manager to establish your connection. When specifying the Route on the
Connection Manager Servers tab, you can manually enter the external IP address
so traffic is routed appropriately.
Simulating a connection
Storage Mirroring Recover offers a simple way for you to simulate a connection in order
to generate statistics that can be used to approximate the time and amount of bandwidth
that the connection will use when actively established. This connection uses the TDU
(Throughput Diagnostics Utility), which is a built-in null (non-existent) target to simulate a
real connection. No data is actually transmitted across the network. Since there is no
true connection, this connection type helps you plan for a disaster recovery solution.
Before and after simulating your connection, you should gather network and system
information specific to Storage Mirroring Recover operations. Use the DTInfo utility to
automatically collect this data. It gathers Storage Mirroring Recover log files; Storage
Mirroring Recover and system settings; network configuration information such as IP,
WINS and DNSaddresses; and other data which may be necessary in evaluating
