Harmonic MediaGrid Release 4.1
Configuring High Bandwidth ContentBridges in a High Availability (HA) Pair
4. By default, the utility walks you through the process of creating an HA pair. The utility allows
you to select which High Bandwidth ContentBridge will be the preferred node and which will
be the other node.
5. Once the HA pair configuration is complete, you may view the status of the HA pair in
SystemManager. See
Viewing HA Paired High Bandwidth ContentBridges in SystemManager
.
Possible Uses for the HA Pair Utility
Other than creating an HA Pair, note the following additional uses for the HA Pair utility:
Changing the preferred node
: To change the preferred node in an HA pair, run the
following:
./hapair --force --create
When the HA Pair utility runs, specify a different preferred node.
To remove an HA pair configuration
: To remove an HA pair configuration, run the following:
./hapair --force --destroy
When the HA Pair utility runs, specify the HA pair you wish to destroy. Note that destroying an
HA pair does not affect the operation of either High Bandwidth ContentBridge that was
previously paired.
Replacing a High Bandwidth ContentBridge in an HA pair
: To replace a High Bandwidth
ContentBridge in an HA pair:
Remove the HA pair configuration for the High Bandwidth ContentBridge you wish to
replace by running:
./hapair --force --destroy
Note that in some cases, if the High Bandwidth ContentBridge you wish to replace is
unaccessible, you may not be able to remove the HA pair configuration.
Remove the original High Bandwidth ContentBridge, install the new one, and configure it
according to the instructions in “Replacing a High Bandwidth ContentBridge” in the
Harmonic MediaGrid Component Replacement Guide
.
Create a new HA pair by running the HA pair utility and entering the desired IP address
for the new High Bandwidth ContentBridge.
Viewing HA Paired High Bandwidth ContentBridges in SystemManager
Once you have configured an HA pair, you can view the status of each device in the pair using
SystemManager. From the
Configuration
tab in SystemManager, click the
Servers & Switche
s
icon in the left-hand column and then scroll down to the
High Bandwidth ContentBridges (in HA
mode)
section of the page. See
.
-c
or
--create
Specifies that you want to create an HA pair. This is the default function of
this utility, and does not need to be explicitly specified.
-d
or
--destroy
Specifies that you want to destroy an HA pair. Note that destroying an HA
pair does not affect the operation of either High Bandwidth ContentBridge
that was previously paired.
