Setup Features on an HA Pair
An HA pair requires that you set up identical features on both systems during the same service window. Peers with mismatched features may exhibit unexpected behavior. You should carefully confirm system synchronization at every step.
This procedure uses the designations system-1 as the original active and system-2 as the original standby.
-
Confirm that
system-1 and system-2 are healthy and synchronized. First check system health
with the
show
health command on both systems to confirm they are in identical
states and healthy.
- Verify that both
systems are in identical health with all processes synchronized with the
show
health command.
Note:
The following examples may not accurately portray your Oracle Communications product and version combination.ORACLE-1# show health Media Synchronized true SIP Synchronized true REC Synchronized disabled MGCP Synchronized disabled H248 Synchronized disabled XSERV Synchronized disabled Config Synchronized true Collect Synchronized disabled RADIUS CDR Synchronized true Rotated CDRs Synchronized true IPSEC Synchronized true Iked Synchronized disabled TSCF Synchronized disabled Active Peer Address Redundancy Protocol Process (v3): State Active Health 100 Lowest Local Address 169.254.1.2:9090 1 peer(s) on 2 socket(s): system-2: v3, Standby, health=100, max silence=1050 last received from 169.254.1.1 on wancom1:0 ORACLE-2# show health Media Synchronized true SIP Synchronized true REC Synchronized disabled MGCP Synchronized disabled H248 Synchronized disabled XSERV Synchronized disabled Config Synchronized true Collect Synchronized disabled RADIUS CDR Synchronized true Rotated CDRs Synchronized true IPSEC Synchronized true Iked Synchronized disabled TSCF Synchronized disabled Active Peer Address 169.254.2.2 Redundancy Protocol Process (v3): State Standby Health 100 Lowest Local Address 169.254.1.1:9090 1 peer(s) on 2 socket(s): system-1: v3, Active, health=100, max silence=1050 last received from 169.254.2.2 on wancom2:0
Next, confirm that both the saved and running configurations across both systems are at the same version number. The following example verifies that system-1 and system-2 all share version 5 of their current and running configurations. If the configurations are out of sync, use the save-config and activate-config commands to fix this.- Verify that the
current configurations are in sync on both system-1 and system-2 with the
display-current-cfg-version
command.
ORACLE-1# display-current-cfg-version Current configuration version is 5 ORACLE-2# display-current-cfg-version Current configuration version is 5
- Verify that the
running configurations are in sync on both system-1 and system-2 with the
display-running-cfg-version
command.
ORACLE-1# display-running-cfg-version Running configuration version is 5 ORACLE-2# display-running-cfg-version Running configuration version is 5
- Verify that both
systems are in identical health with all processes synchronized with the
show
health command.
- Self-provision features on system-1 with the setup entitlements command. This procedure is explained in the Setup Entitlements task, but DO NOT reboot the system at this point.
-
Save and activate
the configuration on system-1.
ORACLE-1# save-config checking configuration Save-Config received, processing. waiting for request to finish Request to 'SAVE-CONFIG' has Finished, Save complete Currently active and saved configurations do not match! To sync & activate, run 'activate-config' or 'reboot activate'. ORACLE-1# activate-config Activate-Config received, processing. waiting for request to finish Request to 'ACTIVATE-CONFIG' has Finished, Activate Complete
- Install License-key enabled features on system-1 with the licenses configuration element. This procedure is explained in the Add a license task, but DO NOT reboot the system at this point. Perform a save- and activate- as performed in the previous step.
-
Repeat steps 2
through 4 on system-2.
At the end of this step, identical features are installed, synchronized, and verified both system-1 and system-2.
- Confirm once again that system-1 and system-2 are synchronized exactly as you did in step 1.
-
Reboot the standby
system-2.
ORACLE-2# reboot
- Wait for system-2 to startup and synchronize, then confirm that system-1 and system-2 are fully synchronized as explained in step 1.
-
Trigger a
switchover from system-1 so that the standby system transitions to active, and
vice-versa.
ORACLE-1# notify berpd force
- Wait while system-2 transitions to the active state, then confirm that system-1 and system-2 are fully synchronized as explained in step 1.
-
Reboot the
newly-standby system-1.
ORACLE-1# reboot
-
Wait for system-1
to complete rebooting, then confirm that system-1 and system-2 are fully
synchronized as explained in step 1.
At this point both systems should be healthy, synchronized, and contain identical feature configurations.
- If desired, trigger a switchover between the two systems in the HA node so the originally active system (system-1) assumes the active role again.
