Major update WhatMatrix Data Protection comparison

Yannick Arens 1 Comment

In the last months, we have worked hard to re-think and update the data protection category. Today we are happy to announce that the new comparison is LIVE!

Data Protection Overview

Data Protection is hot again! A long time there were little movements within the data protection space. You had the traditional enterprise backup solutions on one side with products like NetBackup, Commvault and Backup Exec and on the other side the upcoming products for Virtual Machines with Veeam and the VMware own products.

With the introduction of hyperconvergence in the on-premise market and more and more companies looking into cloud offerings, the backup space is moving again. Companies like Rubrik and Cohesity are shaking up the data protection space and are focussing on these new technology areas with a more simplified approach. Read More

Yannick Arens Leave a comment

This week I’m at the SDDC consulting training at the VMware EMEA HQ in Staines. There is a really full program with presentations and labs about the VMware SDDC portfolio. Products that will be covered in the training are:

  • vRealize Automation
  • vRealize Orchestrator
  • VMware NSX
  • VMware SRM

But the most important focus this week is the integration between all VMware products and 3th party products like InfoBlox and Service Now.

We started yesterday with the installation of a distributed vRealize Automation 6 environment. After clicking thru 281 pages of instruction the installation was finished. Some people in the class had problems with the lab base environment because of time out errors. The reason was a slow network connection not just slow but really really slow… Read More

Upgrading vRealize Automation 7.0.0 to 7.0.1

Yannick Arens Leave a comment

Last week VMware released a new version of vRealize Automation (vRA), version 7.0.1. In this version most of the version 7.0.0 bugs and issues are resolved. In the release notes you can find the list of all resolved issues. In this blog I will guide you through the upgrade process.

It is possible to upgrade to this new version from any supported vRealize Automation 6.2.x version and the latest 7.0 version. In this blog I will focus on an upgrade from version 7.0.0 to version 7.0.1. If you still use an earlier version of vRA you have to upgrade frist to version 6.2.x. The environment we will upgrade is a minimum deployment based on version 7.0.0.

The following steps are required for a successful upgrade of vRealize Automation.

  1. Backup your current installation
  2. Shut down vRealize Automation Windows services on your IAAS server
  3. Configure hardware resources
  4. Download and install upgrades to the vRA appliance
  5. Download and install updates for IAAS
  6. Post Upgrade Tasks

Backup your current installation

Before you start the upgrade it is important to backup some components of the existing installation. If something goes wrong you can always go back to the current version.

Configuration file backup

First start with a backup of the vRA configuration files. This file can be backupped with the following steps:

  1. Login with ssh on the vRA appliance
  2. Make a copy of the following directories:
    • /etc/vcac/
    • /etc/vco/
    • /etc/apache2/
    • /etc/rabbitmq/

First create a directory backup.

mkdir /etc/backupconf

Copy now all directories to this folder:

cp -R /etc/vcac/ /etc/backupconf/

Perform these steps for each folder.

Database backup

Make a SQL backup of the vRA IAAS database. For the integrated postgres database it is enough to snapshot the complete vRA appliance.

  1. Login to the database server
  2. Open the MSSQL Management Console and login
  3. Click left on the vRA database and choose Tasks and choose Backup Up…
  4. Choose the location for the backup and click on OK.
  5. Wait for the completion of the backup.

 

Screenshots of the tenant configuration and users.

If something goes wrong with the upgrade it could be possible that this configuration information is changed. For safety it is recommended to capture this information.

  1. Login as administrator to the vRA interface
  2. Make a Screenshot of your tenants
  3. And the Local Users of the tenant
  4. And the Administrators

 

Backup any files you have customized

The vRA upgrade will possibly delete or modify all customized files. If you want to keep this files please backup them. In our environment we don’t use any customized files.

Create snapshot of the IAAS server

To take a snapshot of the IAAS server is the last step in the upgrade process.

  1. Shutdown the IAAS server and the vRA appliance in the correct order.
    1. Login to vCenter
    2. First select the IAAS VM and select shutdown guest. If the shutdown is complete select the vRA appliance and choose again for shutdown guest.
  2. Right-click on the IAAS VM and select Snapshots and Take Snapshot. Fill in the name of the snapshot and click on OK.
  3. Power On the IAAS VM

Disable the IAAS services

  1. Login on the IAAS server, open msc and stop the following services:
    1. All VMware vCloud Automation agents
    2. All VMware DEM workers
    3. All DEM orchestrator
    4. VMware vCloud Automation Center Service

Configure hardware resources of the vRA appliance

For the upgrade it is necessary to extend the existing disks of the vRA appliance. But before we do this, create a copy of the existing vRA appliance.

  1. Right-click on the vRA appliance, select Clone and Clone to Virtual Machine
  2. Give the VM a unique name and select the resources for the new VM and click on Finish.
  3. Wait for completion.
  4. Right-click on the original VM and select Edit Settings.
  5. Extend the first disks (1) to 50GB and click OK.
  6. Create a snapshot of the VM. Select the VM, click on Snapshots and click Take Snapshot.
  7. Wait for the snapshot.
  8. Power on the vRA VM.
  9. Wait for the machine to start
  10. SSH to the vRA VM and login with the root
  11. Execute the following commands to stop all vRA services:
Service vcac-server stop
Service vco-server stop
Service vpostgres stop
  1. Extend the Linux file system with the following commands:

Unmount swap table:
Swapoff –a

Delete existing partitions and create a 44GB root and 6GB swap partition. This command and the next command return an error about the kernel that is still active at this point. After a reboot at step 13 all changes will be active:
(echo d; echo 2; echo d; echo 1; echo n; echo p; echo ; echo ; echo ‘+44G’; echo n; echo p; echo ; echo ; echo ; echo w; echo p; echo q) | fdisk /dev/sda

Change the swap partition type:

(echo t; echo 2; echo 82; echo w; echo p; echo q) | fdisk /dev/sda

Set disk 1 bootable:

(echo a; echo 1; echo w; echo p; echo q) | fdisk /dev/sda

Register partition changes and format the new swap partition:

Partprobe
Mkswap /dev/sda2

Mount the swap partition:

Swapon –a

  1. Reboot the vRA partition
  2. When the appliance is started again login with SSH and resize the partiation table:

Resize2fs /dev/sda1

  1. Check the resize with command df -h

Install the vRA update

  1. Login on the management interface: https://vRAhostname:5480
  2. Click on the Services tab and check the services. All services should be registered except the iaas-service.

If everything is checked, click on the update tab. If not all services are running and you are using a proxy server, check this Vmware article: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2144067

  1. Click on Check Updates. The new update will be displayed.
  2. Click now on Install update and Click OK.
  3. The follow the installation you can check the following log files:
/opt/vmware/var/log/vami/updatecli.log
/opt/vmware/var/log/vami/vami.log
/var/log/vmware/horizon/horizon.log

The most useful information can be found in the vami.log and updatecli.log. In these log files you can see the download progress and information about the upgrade status.

Use tail –f /opt/vmware/var/log/vami/* to show all log files

  1. Wait untill the update is finished.
  2. If the upgrade is finished, reboot the appliance. Click on the System tab and click on

Upgrading the IAAS server components

The next step in this process is to upgrade the IAAS components. The IAAS installer will also upgrade the MSSQL database. In earlier upgrade processes it was needed to separately upgrade the database. To start the IAAS upgrade, follow the following steps:

  1. Open your favorite webbrowser and go to: https://vRAhostname:5480/installer
  2. Click the IAAS installer Save the prompted file. (Do not change the filename!)
  3. Open the installer and follow the wizard.
  4. Accept the license agreement and click on Next.
  5. Provide the Appliance Login Information. Click on Next.

  1. Choose for Upgrade. Click on Next.
  2. Provide the correct Service Account for the component services and the authentication information of the SQL server. Click on Next.
  3. Accept the certificate of the SSO Default Tenant and provide the SSO Administrator Credentials. Click on Next.
  4. Click now on Upgrade to start the upgrade.
  5. Click on Next and finish to complete the IAAS upgrade.

Post upgrade tasks

After the IAAS upgrade first check the correct operation of the vRA appliance. Click on the infrastructure tab and click on endpoint. Verify the endpoint overview is correct. Next try to request a blueprint and check if everything will finish successful.

If everything is correct, the last step is the upgrade of the vRA agents on the OS templates. The new agents also contain some bug fixes. In our environment we use CentOS and Windows Operating Systems. We will first start with the upgrade of the CentOS agent followed by the Windows Agent.

CentOS agent

  1. Convert the CentOS template to a VM and boot the VM.
  2. Download the prepare_vra_template.sh script from the following location: https://vRAhostname.local:5480/service/software/download/prepare_vra_template.sh
  3. Allow execution of the script with:

chmod +x prepare_vra_template.sh

  1. Execute the script: ./prepare_vra_template.sh.
  2. Follow the wizard and provide the correct information. I choose for vSphere, no certificate check and the install Java.
  3. Wait for completion and shutdown the VM.
  4. Convert the VM back to a template.

Windows Agent

For the upgrade of the Windows Agent we will use the script made by Gary Coburn. He developed a script that will install all the needed components and the vRA agent on Windows. Thanks to my colleague Ronald van Vugt for this modification on this script because of newer java version. The original script is based on vRA version 7.0.0 which included version jre-1.8.0-66. The java version included in version 7.0.1 is newer, so a modification to the script is required.

  1. Download the original script from here or here. And open the script and search for the following line:
    $url=”https://” + $vRAurl + “:5480/service/software/download/jre-1.8.0_66-win64.zip”
  1. This line must be edited to:
    $url=”https://” + $vRAurl + “:5480/service/software/download/jre-1.8.0_72-win64.zip”
  1. If the script is edited run the script with the following parameters:

./prepare_vra_template.ps1 vra-hostname iaas-hostnamePasswordofDarwinUser

  1. The script will sometimes ask for confirmation.
  2. Wait till the installation is complete.
  3. Shutdown the VM and convert it again to a template.

Verify the installation

Now request some of your blueprints to verify the correct operation of the vRA appliance, IAAS server and the guest agents. If everything is OK, then it is time to delete the snapshots of the vRA appliance and IAAS server.

  1. Select the VM, choose for snapshots and Manage Snapshots
  2. Delete the snapshot you have made before installation.
  3. Do this for both VMs

Conclusion

Before executing this upgrade in a production environment it is recommended to plan the upgrade and verify that all dependencies will work after the upgrade. Also plan enough time for this upgrade, so you have the time to check and verify the installation.
