4.3.4 Adding and Switching Over Standby NOAM Server

Perform the following procedure to add and switchover Standby NOAM server.

Add 9.0.X NOAM vDSR instance in the server group again on DSR 8.6.X Active NOAM, by performing the following steps:
1. Log in to DSR 8.6.X Active NOAM GUI using VIP.
2. Navigate to Configuration from Main Menu, then select Servers.
3. Click Insert.
4. Add the following details for vDSR 9.0.1 NOAM:
  - Enter NOAM hostname
  - Update Role as Network OAM&P
  - Hardware Profile as DSR Guest
  - Select the Noam Network element name
  - Configure XMI and IMI IP's and NTP server IP
5. Click Ok.
6. Navigate to Configuration from Main Menu, then select Server Groups.
7. Select the NOAM server group and click Edit.
8. Select the 9.0.X vDSR Noam instance to add to the NOAM Server group. Then, click Ok to save the changes and wait for 5 minutes.
If the Max Allowed role of 9.0.X vDSR Noam instance is not Active, then navigate to Status & Manage from Main Menu, then select HA. Change Standby NOAM Max Allowed HA role to Active by clicking Edit.
Enable the Server, by performing the following steps:
1. ssh to vDSR 9.0.1 NOAM VM and run the following commands to disable the upgrade barrier feature:
```
iset -fvalue=1 IdbParamDef where "param='IdbDisableUpgBarrier'"
sudo init 6
```
2. Log in to 8.6.X Active NOAM GUI using VIP.
3. Navigate to Status & Manage from Main Menu, then select Server.
4. Select Standby vDSR 9.0.X NOAM and click Restart.
To verify servers, perform the following steps:
1. Log in to the XMI IP of the vDSR 9.0.1.
2. Navigate to Configuration from Main Menu, then select Servers.
3. Verify if the screen displays data for all the servers in the topology.
Note:
If this verification step fails, do not proceed further. For further help, contact My Oracle Support (MOS).

Run the following command, if any DSR application (such as PCA, FABR or RBAR) is activated and enabled on DSR.
```
/usr/TKLC/dsr/bin/migrateNonReplicatedData
```
Note:
This step is not required if none of the DSR applications are activated or enabled.
To switchover the role of Active NOAM to standby NOAM and standby NOAM to Active NOAM, perform the following steps:
1. Log in to DSR 8.6.X Active NOAM GUI using XMI.
2. Navigate to Status & Manage from Main Menu, then select HA and change Max Allowed HA Role of Active NOAM to Standby.
  
  Note:
  Now vDSR NOAM instance is Active server and BM 8.6.X NOAM is Standby server.
