Customer Method to Install Life Cycle Manager 

The Ribbon Life Cycle Manager (LCM) provides SBC upgrades in AWS. Once the LCM AMI is launched, files aws_access.yml and upgrade-revert.yml templates (needed for upgrade) are located in the user-specified path.

Example: /home/ec2-user/9.2/iac/management/SBC/upgrade

Prerequisite

• Determine a Linux AMI to use for the LCM using the procedure in Locate Linux AMI ID for use in LCM deployments.
• Retrieve the RBBN LCM scripts from the Ribbon Support Portal.
  • The minimum supported version is iac_sustaining_22.05_b296.tar.gz

Steps

1. Launch a t2.micro instance with LCM AMI.

2. Once successfully instantiated, log into the instance as ec2-user and switch to root:

   Code Block
   ssh -i lcm.pem ec2-user@<LCM instance IP address> sudo su -

   
   

3. Create a directory within /home/ec2-user/ using the command:

   Code Block
   mkdir /home/ec2-user/iac

   
   

4. Copy the LCM tarball IAC package to /home/ec2-user/iac.

5. Untar the tarball inside /home/ec2-user/iac using the command:  

   Code Block
   tar -xzvf iac_sustaining_*.tar.gz

   
   

6. Change to the /home/ec2-user/iac directory and view the README file for any updated instructions.

7.  Install python-pip package using method appropriate for OS - see examples:

   1. Amazon Linux 2 AMI (HVM), SSD Volume Type (x86_64): amazon-linux-extras install epel; yum install -y python-pip
   2. CentOS7 : yum install -y epel-release; yum install -y python2-pip
   3. RHEL7: yum install -y python2-pip
   4. Debian9/Ubuntu18: apt-get install python-pip

8. Install Python virtual environment.

   Code Block
   pip2 install virtualenv

   
   

9. Create virtual environment and provide a name e.g. 'iacenv'.

   Code Block
   virtualenv -p /usr/bin/python2 iacenv

   
   

10. Activate virtual environment.

    Code Block
    source iacenv/bin/activate

    
    

11. Complete the LCM setup by installing the required packages and setup the environment.

    Code Block
    /setup.py

    
    

12. Change directory to /home/ec2-user/iac/management/SBC/upgrade.
13. List the contents of the directory.
14. Ensure the following files are present:
    1. upgrade.py
    2. aws_access.yml
    3. upgrade-revert.yml

Customer Methods for Upgrading and Reverting

Prerequisites

• The new SBC and LCM AMI must be uploaded and available in AWS.
• You must have an AWS Instance (t2.micro) with installed Life Cycle Manager (LCM) AMI. (The default aws_access.yml, upgrade-revert.yml, will be present in the /home/ec2-user/iac/management/SBC/upgrade/ directory of the LCM instance.)

Steps

1. Open a session to the Life Cycle Manager instance (LCM) and switch to root.

   Code Block
   ssh -i lcm.pem ec2-user@<LCM instance IP address>

   
   

2. Activate virtual environment.

   Code Block
   source iacenv/bin/activate

   
   

3. Change to /home/ec2-user/iac/management/SBC/upgrade and enter the workflow directory:
   

   Code Block
   cd /home/ec2-user/iac/management/SBC/upgrade

   
   

4. Edit the file /home/ec2-user/iac/management/SBC/upgrade/aws_access.yml to provide AWS access details and HA pairing information. This information is used for mapping HA pairs. An example of a completed aws_access.yml file is shown below.
   

   Info
   title Note
   Use either the private managment IP address or the elastic IP address of instance1/instance2. Whichever you chose, ensure the IP address is reachable from the LCM server to the SBC SWe.

Overview

The SBC on AWS supports upgrades and reverts from the following releases to 12.00.xx. 

Due to enforced security features (admin ssh key requirement), and cgroup support, Ribbon requires updating SBC instance user-data in prior releases before attempting an upgrade.

Refer to Linuxadmin sudo Permissions for SBC SWe in AWS for more information about ssh key requirements.

Refer to Implement C-group Support for Third-Party Software Installations for more details about Linux cgroup support.  If the user wishes to use this feature after the upgrade, the user-data parameters ThirdPartyCpuAlloc and ThirdPartyMemAlloc must be set to a value other than zero(0) prior to upgrade.

After user-data updates are complete, perform the normal Replacement Upgrade/Revert of the SBC instance in AWS in accordance with Replacement Upgrade for AWS.

HA SBC Upgrade

HA SBC Pre-Upgrade Steps

To update the user-data to include admin ssh keys and 3rd Party cgroup information for an HA SBC pair, complete the following procedure first on the standby SBC, and then on the formerly active SBC.

Update Standby SBC user-data

1. Log onto the standby SBC management IP as user linuxadmin.

sudo to root and verify that this unit has a "current host role" indicating standby using the swinfo command.

Code Block

linuxadmin@vsbc2:~$ sudo su [root@vsbcSystem-vsbc2 linuxadmin]# swinfo =================================================== SERVER: vsbc2 OS: V06.00.00-S406 SonusDB: V07.00.00-S406 EMA: V07.00.00-S406 SBC: V07.00.00-S406 SBC Type: isbc Management mode: xxx Build Number: xxx =================================================== Installed host role: standby Current host role: standby =================================================== =================================================== SERVER: vsbc1 OS: V06.00.00-S406 SonusDB: V07.00.00-S406 EMA: V07.00.00-S406 SBC: V07.00.00-S406 SBC Type: isbc Management mode: xxx Build Number: xxx =================================================== Installed host role: active Current host role: active ===================================================

2. Exit standby unit.

3. Log into the active unit as admin.

4. Ensure the current role active SBC instance sync status shows syncCompleted and app IP and versions are correct.

   Code Block
   title Verify sync status
   admin@vsbc1> show table system rgStatus ACTUAL CE ASSIGNED CURRENT NODE SERVICE INSTANCE RG NAME NAME ROLE ROLE ID ID SYNC STATUS USING METAVARS OF APP VERSION ------------------------------------------------------------------------------------------------------------------------------ vsbc1-172.31.11.73 vsbc1 active standby 1 1 unprotectedRunningStandby vsbc1-172.31.11.73 V07.00.00S406 vsbc2-172.31.11.101 vsbc2 standby active 2 0 syncCompleted vsbc2-172.31.11.101 V07.00.00S406

5. Log onto AWS.

6. Click the Services drop-down list.
   The Services list is displayed.

7. Click EC2 from Management Tools section.

   To stop the Unit

8. Login to the standby unit as linuxadmin and sudo to root using (sudo su -)
9. Stop the instance using the command "shutdown -h now".

10. Using the left navigation panel of the AWS EC2 dashboard, navigate to INSTANCES > Instances.

11. Locate the standby Instance in the list. (for example, if using EIP for management IP, enter the following into the instances search bar type "Public IP : <standby management ip>" and hit enter to quickly find the instance)

Once the Instance State shows stopped, proceed to the next step.

12. password: "myAdminPassword"

    
    

Upgrading

1. Edit the file /home/ec2-user/iac/management/SBC/upgrade/upgrade-revert.yml to provide AMI ID, Upgrade Tag and order of instance upgrade to the new SBC version. The following example provides the  AMI version to use for the upgrade and specifies to upgrade instance i-0987654321dcba and then instance i-0123456789abcd.
   

   Code Block

HA SBC Upgrade Steps

Once the pre-upgrade steps are completed successfully, perform the upgrade at Replacement Upgrade for AWS.

1. - "i-instance-id-4" upgradeGroup2: tag: "test2" instances: - "i-instance-id-1" - "i-instance-id-3"

   
   

2. From the LCM session /home/ec2-user/iac/management/SBC/upgrade, run the upgrade command with aws_access.yml and upgrade-revert.yml as inputs:

   Code Block
   ./upgrade.py -a aws_access.yml -u upgrade-revert.yml

   
   

   Info
   For an offline upgrade, use the command:  ./upgrade.py -a aws_access.yml -u upgrade-revert.yml -o

   
   

   Info
   Upgrade progress and logs are shown on-screen and also logged in /home/ec2-user/9.2/iac/management/log/SBC/upgrade/aws/latest.

   
   

3. After successfully upgrading all nodes listed in upgrade-revert.yml, timestamped logs are moved to /home/ec2-user/9.2/iac/management/log/SBC/upgrade/aws/history.

   Info
   Volumes with older software versions are left intact on AWS in case they are needed for future reversions. Information about these volumes is stored in the file with instance-id as part of its name. Do not delete these older volumes – you must have these volumes in order to perform a reversion.

   
   

Reverting

1. Edit the file /home/ec2-user/iac/management/SBC/upgrade/upgrade-revert.yml by designating the instances to revert. The following example provides a list of instances. 

   Info
   The reversion process runs in parallel on all the instances, and could impact service. Make sure that all the instances of a redundancy group get reverted to same SBC version, failure to maintain the same version within a group will cause unknown behavior and could cause a service outage.
