Replication in an HA Environment
It is required that the IP addresses for data/virtual and monitor/heartbeat must be in the same IP
subnet on each interface. Each interface must be able to access the IP address of its HA partner.
Note:
Replication is not supported between HA partners.
Use the exact same commands to configure the
rep0
interface for the HA partner as you issued
for the HA primary in the partner pair. The following example uses 7700 FSP Controller references.
7700 FSP Controller B Login
Log in to HA partner (7700 FSP Controller B) CLI while HA is disabled on the HA primary (7700
FSP Controller A), and use the following commands as shown:
1.
Configure 7700 FSP Controller B
rep0
port using these commands:
2.
Test basic access between the two 7700 FSP Controllers (7700 FSP Controller B to 7700 FSP
Controller A) by using the following commands:
Confirm that
rep0
for 7700 FSP Controller A indicates its MAC address.
3.
Add a replication route from 7700 FSP Controller B
rep0
to Site2.
For details, see step 4 and step 6 in
Configuring Site 1, 7700 FSP Controller A
4.
Return to 7700 FSP Controller A to complete HA configuration and enable HA.
Table C.3 provides host, virtual IP address, and monitor IP address examples for
rep0
when
setting up HA.
