How to Upgrade VCS from 7.4.2 to 8.0 in RHEL
Veritas Cluster Server upgrade can be done smoothly by using the Install Bundles feature. This installer allows you to perform the upgrade directly to a base, maintenance, patch level or a combination of multiple patches and packages together in one go because the installer has the ability to merge all these packages. So, you don’t have to perform two or more install actions to install or upgrade systems to maintenance levels or patch levels.
If you are on an unsupported operating system version, ensure that you first upgrade to a supported verison of the operating system then perform VCS upgrade.
In this article, we will show you how to upgrade Veritas Cluster Server from 7.4.2 or 7.4.3 to 8.0, including Red Hat upgrade from RHEL 7.9 to RHEL 8.8.
Our Environment
- Two node Active-Passive VCS cluster 7.4.2 with RHEL 7.9
- Node1 – 2gvcsnode1 – 192.168.10.110
- Node2 – 2gvcsnode2 – 192.168.10.111
Upgrade Scenario
Our upgrade path is as follows.
- Red Hat upgrade from RHEL 7.9 to RHEL 8.8 using Leapp utility
- Veritas Cluster Server upgrade from 7.4.2 or 7.4.3 to VCS 8.0 node by node upgrade, which minimizes downtime
Prerequisites
Stop the VCS cluster on the system where you want to perform the RHEL 8.8 upgrade.
hastop -local
Rename the '/etc/llttab' file as shown below.
mv /etc/llttab /etc/llttab.save
System Upgrade
We have already added an article on Red Hat upgrade from RHEL 7.9 to RHEL 8.8 using Leapp utility. So follow the article for RHEL upgrade.
After RHEL upgrade, move ‘/etc/llttab’ file to original state.
mv /etc/llttab.save /etc/llttab
Check the Status of VCS cluster in another node (Node-1), at this point of time the Node-2 status would show as 'EXITED' because the ‘/etc/llttab’ was disabled before restarting the server.
hastatus -sum -- SYSTEM STATE -- System State Frozen A 2gvcsnode1 RUNNING 0 A 2gvcsnode2 EXITED 0 -- GROUP STATE -- Group System Probed AutoDisabled State B ClusterService 2gvcsnode1 Y N OFFLINE B ClusterService 2gvcsnode2 Y N ONLINE B apachesg 2gvcsnode1 Y N OFFLINE B apachesg 2gvcsnode2 Y N ONLINE
Downloading Veritas InfoScale
As mentioned earlier, we need to download Veritas InfoScale base package, maintenance package, and required patches together. For this upgrade, you need to download following five archive files.
Veritas_InfoScale_8.0_RHEL.tar.gz #Base Package cpi-Patch-8.0.0.1400.tar.gz #CPI Patch infoscale-rhel8_x86_64-Patch-8.0.0.1800.tar.gz #Cumulative Patch infoscale-rhel8.7_x86_64-Patch-8.0.0.2600.tar.gz #Common Updates Patch infoscale-rhel8.8_x86_64-Patch-8.0.0.2700.tar.gz #RHEL8.8 Patch
Creating directory structure
Create a proper directory structure and move the files to respective directory to avoid confusion. I have created the following directories as per my convenient.
/backup/vcs8 #Base Package Path /backup/vcs8_cpi_patch_1400 #CPI_Patch Path /backup/vcs8_patch_1800 #Patch_1 Path /backup/vcs8_patch_2600 #Patch_2 Path /backup/vcs8_patch_2700 #Patch_3 Path
Extracting the Packages
Extract the packages to respective location as created above.
tar -xf Veritas_InfoScale_8.0_RHEL.tar.gz -C /backup/vcs8 tar -xf cpi-Patch-8.0.0.1400.tar.gz -C /backup/vcs8_cpi_patch_1400 tar -xf infoscale-rhel8_x86_64-Patch-8.0.0.1800.tar.gz -C /backup/vcs8_patch_1800 tar -xf infoscale-rhel8.7_x86_64-Patch-8.0.0.2600.tar.gz -C /backup/vcs8_patch_2600 tar -xf infoscale-rhel8.8_x86_64-Patch-8.0.0.2700.tar.gz -C /backup/vcs8_patch_2700
Performing Upgrade
You can follow the below instruction for smoother upgrade.
Make a Note: CPI path must included in the beginning of the upgrade command as shown below.
Syntax:
./installer -require [Complete_Path_of_the_CPIscript] -patch_path [Path_to_the_patch 1] -patch2_path [Path_to_the_patch 2] -patch3_path [Path_to_the_patch 3]
Navigate to VCS 8.0 base directory and run installer as shown below (Please use your package location instead of ours). It is also advisable to use the latest CPI patch, other required patches along with the installer for a smoother upgrade. You can add a maximum of five patches using ‘-patch_path’ in a single command.
cd /backup/vcs8/dvd1-redhatlinux/rhel8_x86_64 ./installer -require /backup/vcs8_cpi_patch_1400/CPI_8.0.0_P14.pl -patch_path /backup/vcs8_patch_1800 -patch2_path /backup/vcs8_patch_2600 -patch3_path /backup/vcs8_patch_2700
When you start the installer, the installer starts the product installation program with a copyright message. It then specifies where it creates the logs. Make a note of the directory name and path where the logs get stored.

From the Task Menu, Select 'G' and hit 'Enter' to perform the VCS upgrade.
From the submenu, select which method you want to perform the upgrade. In our case, it’s Full Upgrade, so simple hit 'Enter' to go with default option.

The installer suggests system names for the upgrade. Press Enter to upgrade the suggested systems, or enter the name of any one system in the cluster on which you want to perform a full upgrade and then press Enter.
To minimize the downtime, we will be upgrading one by one node (Phase upgrade), so enter the specific hostname and press 'Enter'.
Enter the system names separated by spaces: [q,?] (2gvcsnode1 2gvcsnode2) 2gvcsnode2
Now, the installer performs various check on the system for the upgrade and ensure communications, release compatibility, and version information. It may present warnings and also report if anything failed during this check.

The following notes were discovered on the systems:
CPI NOTE V-9-40-2930 You are performing ENTERPRISE phased upgrade phase 1 on the systems. The first subcluster will be upgraded.
CPI NOTE V-9-30-1114 InfoScale Enterprise version 7.4.2.3100 will be upgraded to InfoScale Enterprise version 8.0.0.0000 on 2gvcsnode1
The following warnings were discovered on the systems:
CPI WARNING V-9-40-1442 Kernel Release 4.18.0-477.13.1.el8_8.x86_64 is detected on 2gvcsnode1, which is not recognizable by the installer. It is strongly recommended to check if on SORT (https://sort.veritas.com) before continue.
CPI WARNING V-9-40-4050 The vxconfigd utility could not be started on 2gvcsnode1. Upgrading VRTSvxvm in this scenario can result in configuration errors, or data loss for Veritas Volume Manager objects. Continue if you are sure that there are no Veritas Volume Manager objects on the host.
CPI WARNING V-9-40-3952 Cannot check for open volumes on 2gvcsnode1 because the vxconfigd process is not in enabled mode. You must affirm that there are no open volumes if you want to continue.
CPI WARNING V-9-40-2947 Not all the members of the cluster, 2gvcsnode, are included in this upgrade. We recommend that you upgrade all the members of the cluster together, unless you plan to perform a phased upgrade for the cluster.
CPI WARNING V-9-40-2916 VCS is not running before upgrade on 2gvcsnode1. Make sure all the configurations are valid before upgrade.
Review and check if all ‘WARNINGS’ can be ignored or if any action is required before moving to the next step.
In our case, all warnings can be ignored, so we can proceed to the next step. For the below questions, input 'y' for all and hit 'Enter'.

Uninstalls old RPMs after the installer stops the associated VCS processes.
Make a Note: If any RPM uninstall fails at this stage, you will be prompted to exit the installer, but continue to the next stage by entering 'n', otherwise you will be faced with a situation where you will have to do a fresh install.

Veritas Cluster Server upgrade from 7.4.1/7.4.2 to 8.0 has been completed successfully on the Second Node (Node-2). After the Veritas upgrade, perform a sanity restart to verify that all Veritas services start as expected and were able to join the cluster without any issues.
reboot or init 6
After restarting, check the status of Node-2 in the cluster. If it joins automatically without any problem, proceed to the next step. But if it doesn’t join then we need to do further troubleshooting based on the logs available in ‘/var/VRTSvcs/log/engine_A.log’.
hastatus -sum -- SYSTEM STATE -- System State Frozen A 2gvcsnode1 RUNNING 0 A 2gvcsnode2 RUNNING 0 -- GROUP STATE -- Group System Probed AutoDisabled State B ClusterService 2gvcsnode1 Y N OFFLINE B ClusterService 2gvcsnode2 Y N ONLINE B apachesg 2gvcsnode1 Y N OFFLINE B apachesg 2gvcsnode2 Y N ONLINE
If the upgraded node was joined the cluster and the cluster is healthy, move the service group to the upgraded node. In this scenario, Node-2 is running with VCS 8.0
hagrp -switch apachesg -to 2gvcsnode2
Perform an application sanity check. If it works as expected. Do the upgrade on the other node as well ‘2gvcsnode1’ using the above steps.
Wrapping Up
In this tutorial, we’ve shown you how to upgrade Veritas Cluster Server (VCS) from 7.4.1 or 7.4.2 to 8.0 with necessary patches on RHEL 8.8, along with RHEL 8.8 upgrade from RHEL 7.9.
In the next post, we’ll show you list of frequently used VCS commands and their usage.
