In this scenario, the standby node of an HA pair has failed.
So, you must add a new standby node. System administrators can use
the imaserver HighAvailability commands
on the command line.
The two Eclipse Amlen appliances
must be physically connected. For more information about connecting
appliances, see Configuring the system for High Availability.
The administrative state (AdminState) of the two appliances must also
be enabled. Use the enable ethernet-interface or edit
ethernet-interface command to enable the administrative
state of the appliances.
You can configure appliances for high availability by
using the command line or by using the Amlen WebUI. For more
information about using the Amlen WebUI to configure
appliances for high availability, see Add
a new standby node after the original standby node failed by using
the GUI. In this scenario, the content of the store and configuration
of Appliance A is preserved and Appliance A does not require restarting.
- On Appliance C enter the following command:
imaserver update
HighAvailability "EnableHA=True" "Group=Group"
Where:
- Group
- Group is used to automatically configure appliances to pair with
each other.
- This value must match the value on Appliance A.
- The value can be a maximum of 128 characters.
- Clean the store on Appliance C only.
Failing
to do so will cause both nodes to go into maintenance mode. Enter
the following commands:
imaserver runmode maintenance
imaserver stop
imaserver start
imaserver runmode clean_store
imaserver stop
imaserver start
- Change Appliance C to production mode.
imaserver runmode production
- Stop and then restart the Eclipse Amlen server for Appliance
C.
imaserver stop
imaserver start
You can view high availability configuration details of the Eclipse Amlen appliance by using the imaserver show
HighAvailability command. You can view information about the high availability role of
theEclipse Amlen appliance by using the imaserver
status command.
