Planning for the procedure

Background knowledge

This procedure assumes that:

  • you are installing into an existing VMware vSphere deployment which has pre-configured networks and VLANs; this procedure does not cover setting up a VMware vSphere deployment from scratch

  • you have deployed a SIMPL VM, unpacked the CSAR, and prepared an SDF.

Reserve maintenance period

This procedure does not require a maintenance period. However, if you are integrating into a live network, we recommend that you implement measures to mitigate any unforeseen events.

Plan for service impact

This procedure does not impact service.

People

You must be a system operator to perform the MOP steps.

Tools and access

You must have access to the SIMPL VM, and the SIMPL VM must have the right permissions on the VMware vSphere deployment.

Method of procedure

Note Refer to the SIMPL VM Documentation for details on the commands mentioned in the procedure.

Step 1 - Validate ShCM RVT configuration

Validate the configuration for the ShCM nodes to ensure that each ShCM node can properly self-configure.

To validate the configuration after creating the YAML files, run

rvtconfig validate -t shcm -i <yaml-config-file-directory>

on the SIMPL VM from the resources subdirectory of the ShCM CSAR.

Step 2 - Upload ShCM RVT configuration

Upload the configuration for the ShCM nodes to the CDS. This will enable each ShCM node to self-configure when they are deployed in the next step.

To upload configuration after creating the YAML files and validating them as described above, run

rvtconfig upload-config -c <tsn-mgmt-addresses> -t shcm -i <yaml-config-file-directory> (--vm-version-source this-rvtconfig | --vm-version <version>)

on the SIMPL VM from the resources subdirectory of the ShCM CSAR.

See Example configuration YAML files for example configuration files.

An in-depth description of RVT YAML configuration can be found in the Rhino VoLTE TAS Configuration and Management Guide.

Deployments using SIMPL 6.7.3

Step 3 - Deploy the OVA

Run csar deploy --vnf shcm --sdf <path to SDF>.

This will validate the SDF, and generate the terraform template. After successful validation, this will upload the image, and deploy the number of ShCM nodes specified in the SDF.

Warning Only one node type should be deployed at the same time. I.e. when deploying these ShCM nodes, don’t deploy other node types at the same time in parallel.

Backout procedure

To delete the deployed VMs, run csar delete --vnf shcm --sdf <path to SDF>.

You must also delete the MDM state for each VM. To do this, you must first SSH into one of the MDM VMs. Get the instance IDs by running: mdmhelper --deployment-id <deployment ID> instance list. Then for each ShCM VM, run the following command:

curl -X DELETE -k \
     --cert /etc/certs-agent/upload/mdm-cert.crt \
     --cacert /etc/certs-agent/upload/mdm-cas.crt \
     --key /etc/certs-agent/upload/mdm-key.key \
     https://127.0.0.1:4000/api/v1/deployments/<deployment ID>/instances/<instance ID>

Verify that the deletion worked by running mdmhelper --deployment-id <deployment ID> instance list again. You may now log out of the MDM VM.

You must also delete state for this node type and version from the CDS prior to re-deploying the VMs. To delete the state, run rvtconfig delete-node-type --cassandra-contact-point <any TSN IP> --deployment-id <deployment ID>
--site-id <site ID> --node-type shcm
(--vm-version-source [this-vm | this-rvtconfig] | --vm-version <vm_version>).

Deployments using SIMPL 6.6.x

Step 3 - Validate the SDF

Run csar validate-vsphere --sdf <path to SDF>.

This will validate the SDF.

Step 4 - Generate the Terraform Template

Run csar generate --vnf shcm --sdf <path to SDF>.

This will generate the terraform template.

Step 5 - Deploy the OVA

Run csar deploy --vnf shcm.

This will upload the image, and deploy the number of ShCM nodes specified in the SDF.

Warning Only one node type should be deployed at the same time. I.e. when deploying these ShCM nodes, don’t deploy other node types at the same time in parallel.

Backout procedure

To delete the deployed VMs, run csar deploy --vnf shcm --delete.

You must also delete the MDM state for each VM. To do this, you must first SSH into one of the MDM VMs. Get the instance IDs by running: mdmhelper --deployment-id <deployment ID> instance list. Then for each ShCM VM, run the following command:

curl -X DELETE -k \
     --cert /etc/certs-agent/upload/mdm-cert.crt \
     --cacert /etc/certs-agent/upload/mdm-cas.crt \
     --key /etc/certs-agent/upload/mdm-key.key \
     https://127.0.0.1:4000/api/v1/deployments/<deployment ID>/instances/<instance ID>

Verify that the deletion worked by running mdmhelper --deployment-id <deployment ID> instance list again. You may now log out of the MDM VM.

You must also delete state for this node type and version from the CDS prior to re-deploying the VMs. To delete the state, run rvtconfig delete-node-type --cassandra-contact-point <any TSN IP> --deployment-id <deployment ID>
--site-id <site ID> --node-type shcm
(--vm-version-source [this-vm | this-rvtconfig] | --vm-version <vm_version>).

Next Step

If you are upgrading a full set of VMs, go to Deploy MAG nodes on VMware vSphere, otherwise follow the verification instructions here: Verify the state of the nodes and processes
