Upgrading M-SBC in N:1 Redundancy Group

In this section:

Prerequisite

Perform the following activities prior to upgrading the M-SBC in an RG.

Download the Software Image

Download the required .QCOW2 and .md5 files from the Customer Portal.

Upload the Software Image to OpenStack

To upload the .QCOW2 file to the OpenStack, navigate to Project > Compute > Images. For more information, refer to Creating a Glance Image.

Check the Status of the Instances

In an M-SBC Redundancy Group, ensure all the five instances (4:1) and the EMS are up and running.

To check the instances, navigate to Project > Compute > Instances. The Instances window is displayed. The Instances window displays the status of the current image.

M-SBC Instances in an RG

Identify the Assigned Standby Instance

To identify the assigned standby instance, perform the following steps:

Log on to CLI of any of the instances as admin user. Execute the following command and check the value of the parameter assignedRole.

> show status system rgStatus
rgStatus vsbc1-192.168.2.3 {
    actualCeName    vsbc1;
    assignedRole    active;
    currentRole     active;
    nodeId          1;
    serviceId       0;
    syncStatus      syncCompleted;
    usingMetavarsOf vsbc1-192.168.2.3;
    appVersion      V06.02.01A013;
}
rgStatus vsbc1-192.168.2.4 {
    actualCeName    vsbc1;
    assignedRole    standby;
    currentRole     standby;
    nodeId          2;
    serviceId       1;
    syncStatus      unprotectedRunningStandby;
    usingMetavarsOf vsbc1-192.168.2.4;
    appVersion      V06.02.01A013;
}

    actualCeName    vsbc1;
    assignedRole    active;
    currentRole     active;
    nodeId          3;
    serviceId       2;
    syncStatus      syncCompleted;
    usingMetavarsOf vsbc1-192.168.2.5;
    appVersion      V06.02.01A013;
}
rgStatus vsbc1-192.168.2.6 {
    actualCeName    vsbc1;
    assignedRole    active;
    currentRole     active;
    nodeId          4;
    serviceId       3;
    syncStatus      syncCompleted;
    usingMetavarsOf vsbc1-192.168.2.6;
    appVersion      V06.02.01A013;
}
rgStatus vsbc1-192.168.2.7 {
    actualCeName    vsbc1;
    assignedRole    active;
    currentRole     active;
    nodeId          5;
    serviceId       4;
    syncStatus      syncCompleted;
    usingMetavarsOf vsbc1-192.168.2.7;
    appVersion      V06.02.01A013;
}

Upgrade Process

Note

The assignedRole standby instance must be upgraded first, followed by the active instances.
Only one instance must be upgraded at a time.

Perform the following steps to upgrade.

On OpenStack, navigate to Project > Compute > Instances. The Instances window is displayed.
From the drop-down list corresponding to the standby instance, select the option Rebuild Instance.

Selecting Rebuild Instance Option

The Rebuild Instance window is displayed.
Click Rebuild Instance to rebuild the instance with the upgraded image details.

Rebuild Instance

The status of the Task column is displayed as Rebuilding.

Rebuilding Process
Repeat the steps (1 to 3 from the Upgrading M-SBC in N:1 Redundancy Group section) to upgrade the active instances one by one. Before upgrading an instance,
check syncStatus field in rgStatus output to ensure that all the currently active instances are in syncCompleted state. The standby instance displays syncStatus as unprotectedRunningStandby. For more information, see section Upgrading M-SBC in N:1 Redundancy Group.
Once the rebuilds are completed, all the instances will be running with the upgraded image details.

Rebuilding Process Completed for All the Instances

Post-Upgrade Monitoring

To verify if the instances are up and running with the upgraded software image:

Log on to CLI of any of the instances as admin user.

Execute the following command and check the appVersion field for each of the instances. Check syncStatus field in rgStatus output to ensure that all the currently active instances are in syncCompleted state. The standby instance displays syncStatus as unprotectedRunningStandby.
