Replace a DP SOAM Server Pair

2.2.6 Replace a DP SOAM Server Pair

Pre-Condition:

Active and Standby DP SOAM servers have stopped functioning.
It has been determined to replace both VMs that host DP SOAM.
Access to primary SDS GUI is available.
DPs are not receiving provisioning database updates.

Prepare for server replacement

Identify the DP SOAM server VM(s) that needs to be replaced:
Hostname: DP SOAM 1

Hostname: DP SOAM 2
Replace old SDS DP SOAM VMs with new SDS SOAM VMs:
1. For VMWare based deployments:
  1. Open the cloud client of your choice, for example, vSphere client and locate the defective DP SOAM server VM.
  2. Power down DP SOAM server VM and remove it from the inventory or disk.
    For more information, see section 2.2 "Creating SDS Guests (VMware)" from Oracle Communications SDS Cloud Installation Guide.
2. For KVM/OpenStack based deployments:
  1. Run the following command to log in to the OpenStack control node:
```
$ ssh admusr@node
```
  2. Run the following command to power down defective DP SOAM server VM and remove it from the inventory or disk:
```
$ nova delete <VM Name>
```
    For more information, see section 2.3 "Create SDS Guest from OVA (KVM/OpenStack)" from Oracle Communications SDS Cloud Installation Guide.
3. For OVM-S/OVM-M based deployments:
  1. Run the following command to log in to the command line interface of the OVM-M:
```
OVM> ssh -l admin <OVM-M IP> -p 10000
```
    Example:
```
[root@manager01 ~]# ssh -l admin 10.240.16.138 -p
10000
admin@10.240.16.138's password:
```
  2. Run the following command to power down SDS VM(s).
```
OVM> stop Vm name=<VM Name>
```
    Note:
    Wait for the VM to have the state stopped.
  3. Run the following command to remove the VM from the inventory or disk:
```
OVM> delete Vm name=<VM Name>
```
    Note:
    Repeat steps 2 and 3 for all the failed VMs.
    
    See, section 2.4 "Creating SDS Guests from OVA (OVM-S or OVM-M)" from Oracle Communications SDS Cloud Installation Guide.
Prepare the new SDS SOAM servers:
1. Perform procedure in section 3.6 "OAM Installation for DP-SOAM Sites" steps 6 to10 from Oracle Communications SDS Cloud Installation Guide.
Restart the SOAM servers:
1. Perform procedure in section 3.7 step 4 "OAM Pairing for DP-SOAM Sites" from Oracle Communications SDS Cloud Installation Guide.
2. Perform procedure in section 3.7 step 6 "OAM Pairing for DP-SOAM Sites" from Oracle Communications SDS Cloud Installation Guide.
Verify DP SOAM servers received SDS provisioning:
1. Log in to the active DP SOAM GUI using the VIP address.
2. Navigate to Status & Manage and Servers.
3. Ensure the new DP SOAM server show norm for DB, Reporting Status, and Application state.

Post-Condition

Both DP SOAM servers are back in service.
DP SOAM configuration changes can be made from DP SOAM GUI.
DPs are now receiving provisioning updates.
