About this upgrade

For information on what's new in QRadar 7.3.1, see: https://www.ibm.com/support/knowledgecenter/SS42VS_7.3.1/com.ibm.qradar.doc/c_qradar_ov_whats_new_731.html These instructions are intended to assist you when you update appliances from QRadar 7.2.8 to QRadar 7.3.1 Patch 3 by using an ISO file. This ISO can update QRadar SIEM, QRadar Risk Manager, and QRadar Vulnerability Manager products from QRadar 7.2.8 to 7.3.1. If you have a software installation, need the latest memory requirements, or are making use of off-board storage, review the QRadar Upgrade Guide to prevent issues.





*This document does not cover all the installation messages and requirements, such as changes to memory requirements or browser requirements for QRadar. To review any additional requirements, see the QRadar Upgrade Guide



Figure 1: If you have QRadar 7.2.8 or later installed, you are not required to install each ISO release to update to QRadar 7.3.1 Patch 3.





Administrator notes

This update includes a change to how login authentication works for fallback LDAP, Radius, or Active Directory on administrator accounts. If the external authentication server is unavailable, not all administrators are able to revert to local administrator passwords without a configuration change. This change was implemented in QRadar 7.3.0 Patch 4 or later. This note is included in 7.3.1 Patch 3 to raise awareness for this change. For more information, see QRadar: External Authentication Fails Due to Password Fallback Change for Administrators . TLS v1.0 and TLSv1.1 is disabled in this release. Connections to the user interface for legacy browsers might be rejected. WinCollect agents at version 7.2.2-2 or older use TLSv1.0 and TLS v1.1 connections to upgrade agents, which is disabled in QRadar 7.3.1 (all patch versions). If you have managed WinCollect agents, you must upgrade to WinCollect 7.2.5 before you install QRadar 7.3.1 Patch 3. WinCollect 7.2.5 is a pre-requisite for QRadar 7.3.1 Patch 3. Standalone WinCollect agents are not impacted by this requirement. Customized routes or static routes that are configured manually in QRadar are not preserved after the upgrade to QRadar 7.3.1 Patch 3 completes. Any iptables rules that you configured should be reviewed and noted for clean-up post installation. The interface names have changed in QRadar 7.3.1 Patch 3 due to the Red Hat Enterprise 7 operating system updates; if you reference the interfaces you must manually update the iptables rules. Each HA appliance must be updated individually by using the ISO file. The SFS file can allow the primary appliance to update the secondary, but the ISO file does not support this functionality. If you run the ISO setup on an HA primary, wait for the update to complete, and then run the setup on the HA secondary. There is no patch "All" option because QRadar 7.3.1 Patch 3 uses an ISO file to upgrade. The ISO must be mounted on the appliance and run locally on each host. If you have a software installation, you need your Red Hat Enterprise ISO and the QRadar ISO. If you have software installations on your own hardware you must read the QRadar Upgrade Guide to understand how to partition your systems appropriately. The QRadar 7.3.1 Patch 3 upgrade will take longer than expected due to the kernel changes to Red Hat 7 Enterprise. Early upgrade customers are reporting 2 to 2.5 hours to upgrade the Console appliance. You should be aware of this longer time frame and plan maintenance accordingly. Utilities or custom scripts that power users might have created for their QRadar deployment should be copied off the system. During the QRadar 7.3.1 Patch 3 update a warning is displayed that only data in /store is going to be preserved. After the appliance reboots, any scripts, 3rd party accounts, or utilities in /tmp, or /, or /root are deleted. ISO files that were mounted initially by using /root, are not impacted because this cleanup occurs later in the installation procedure.



Before you upgrade

Back up your data before you begin any software upgrade and verify that you have recent configuration backups that match your existing Console version. If required, take an on demand configuration backup before you begin. For more information about backup and recovery, see the QRadar Administration Guide .

. HA appliances should have primaries in the online state and secondary as standby for their HA pair status.

If you have off-board storage configured, see the QRadar Upgrade Guide . There are special instructions for administrators with /store using off-board storage.

for partition information. WinCollect 7.2.5 is a pre-requisite for QRadar 7.3.1 Patch 3; all managed agents must be updated. Standalone WinCollect agents are not impacted by this requirement.

All appliances in the deployment must be at the same software and patch level in the deployment.

Verify that all changes are deployed on your appliances. The update cannot install on appliances that have undeployed changes.

A QRadar 7.3.1 Patch 3 ISO is available to upgrade from QRadar 7.2.8 Patch 1 or install a new appliance or virtual machine. Review the QRadar Installation Guide .

. To avoid access errors in your log file, close all open QRadar user interface sessions.

utility to get a CSV file that contains a list of IP addresses for each managed host. If you are unsure of how to proceed when reading these instructions or the documentation, it is best to ask before you start your upgrade. To ask a question in our forums, see: http://ibm.biz/qradarforums .

Ensure that you take the following precautions:

Part 1. Staging files and pretesting your deployment (required)

screen

It is important that you pretest your deployment to ensure that you don't experience unexpected issues when you update to QRadar 7.3.1. A pretest is a common precaution before you install an update so that you can locate potential issues. The pretest does not restart services and can be completed without scheduled downtime. The pretest typically takes between 3 to 5 minutes to complete on each appliance. If for some reason your SSH session is disconnected, you can reconnect to the remote host using

Procedure

The pretest should be completed on all hosts before you attempt to upgrade to QRadar 7.3.1 Patch 3.

Download the QRadar 7.3.1 Patch 3 ISO (5 GB) from the IBM Fix Central website: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=IBM%20Security&product=ibm/Other+software/IBM+Security+QRadar+SIEM&release=7.3.0&platform=Linux&function=fixId&fixids=7.3.1-QRADAR-QRFULL-20180327211425&includeSupersedes=0&source=fc



IMPORTANT: QRadar Incident Forensics and QRadar Network Insights use a unique ISO file to upgrade from 7.2.8 to 7.3.1 Patch 3. See the Fix Central page for those products to download the correct file.

Use SSH to log in to your Console as the root user. Type the following command: screen To make the directory for the update, type:

/opt/qradar/support/all_servers.sh -k “mkdir -p /media/cdrom || umount /media/cdrom" To verify that you have enough space (4GB) in /tmp for the ISO on all appliances, type:

/opt/qradar/support/all_servers.sh -k df -h /root /var/log | tee diskchecks.txt



Best directory option: /root

It is available on all appliance types, and is the best option to host the ISO file.

It is available on all appliance types, and is the best option to host the ISO file. 2nd best directory option: /var/log

This directory is available on all appliances, but there might not be the required space available.

This directory is available on all appliances, but there might not be the required space available. DO NOT USE: /tmp, /store/tmp, or /store/transient for your ISO upgrade. These directories are partitioned as part of the upgrade; you cannot use them as storage locations or mount points for the ISO file .



If the disk check command fails, retype the quotation marks from your terminal, then re-run the command. This command returns the details to both the command window and to a file on the Console named diskchecks.txt. Review this file to ensure that all appliances have at minimum 5GB of space available in a directory to copy the ISO before you attempt to move the file to a managed host. If required, free up disk space on any host that fails to have less that 5GB available.



Reminder: Utilities or custom scripts that you have created for QRadar should be copied off the system. During the 7.3.1 update a warning is displayed that only data in /store will be preserved. Therefore, Scripts, 3rd party utilities in /tmp, or /, or /root will be deleted during the upgrade.



If there is not 4GB of space in /root or /var/log, you must make directory space for the ISO file.

Using WinSCP or SCP, copy the ISO to the /root or /var/log directory on the QRadar Console with 4GB of disk space for the ISO file.

To copy the files to all appliances, type: /opt/qradar/support/all_servers.sh -k -p /root/ Rhe764QRadar7_3_1_ 20180327211425 .stable-7-3-1.iso -r /root

To mount the ISO on all appliances, type the following command: /opt/qradar/support/all_servers.sh -C -k “mount -o loop /root/ Rhe764QRadar7_3_1_ 20180327211425 .stable-7-3-1.iso /media/cdrom"

To pretest the Console appliance, type: /media/cdrom/setup -t

The pretest output is written to the command window. Review this output after the pretest completes.

Use SSH to open an SSH session to the other appliances in your deployment. QRadar Support recommends that you run the pretest on each host to identify issues before the update begins.

To pretest the managed host, type: /media/cdrom/setup -t



Results

If an appliance in your deployment fails the pretest, take the recommended action from the pretest utility. The issue must be resolved before the update to QRadar 7.3.1 Patch 3 begins to prevent downtime for specific appliances. If there are messages you do not understand or want to discuss further, you can use our forums at http://ibm.biz/qradarforums to get advice. You can also open a ticket directly with QRadar Support ( http://ibm.biz/qradarsupport ).





Part 2. Installing the QRadar 7.3.1 Patch 3 ISO on the Console Appliance

These instructions guide you through the process of upgrading an existing QRadar installation at 7.2.8 Patch 1 or later to QRadar 7.3.1 Patch 3. The update on the Console must be completed before you attempt to update any managed hosts to QRadar 7.3.1 Patch 3.

Procedure

You must complete the Staging files and pretesting your deployment procedure before you begin the installation steps.

Use SSH to log in to the Console as the root user. To run the ISO installer on the Console, type the following command: /media/cdrom/setup



Important: Upgrading from QRadar 7.2.8 Patch 1 or later to QRadar 7.3.1 Patch 3 should take approximately 2 hours on a Console appliance.

Wait for the Console primary update to complete. If you have an HA Secondary, you can now update the secondary appliance. Open an SSH session to the HA Console secondary. Type the following command to update the secondary Console: /media/cdrom/setup Wait for the HA Console secondary to complete the update.

A summary of the ISO installation advises you of any issues. If there are no issues, use SSH to log in to the managed hosts and start the installer on each host to run the setup in parallel.

Part 3. Installing the QRadar 7.3.1 ISO on all other managed hosts

After the Console and Console HA secondary are updated to QRadar 7.3.1, the rest of the deployment can be updated. After the Console is updated, you can update Event Processors, Event Collectors, QFlow appliances in any order. You must open an SSH session to each host to run the setup command. Theutility cannot be used to start ISO installations.



If any of your appliances are HA pairs, you must upgrade the primary appliance first.





Procedure

Use SSH to log in to the Console as the root user. Open an SSH session to each managed host and type the following command: /media/cdrom/setup



Important: Upgrades for managed hosts should take approximately 1.5 hours.

Wait for the managed host update to complete. If you have an HA Secondary, you can now update the secondary appliance. Open an SSH session to the manage host HA secondary. Type the following command to update the secondary: /media/cdrom/setup Wait for the HA Console secondary to complete the update.



Results

A summary of the ISO installation advises you of any issues. If there are no issues, run the ISO setup on the Console HA secondary appliance, if you have an HA pair. If you do not have a Console in HA, you can then start SSH sessions to each host and run the setup in parallel.





Part 4. Installation wrap-up

After all hosts are updated, advise your team that they must clear their browser cache before logging in to QRadar SIEM. To unmount the /media/cdrom directory on all hosts, type:

/opt/qradar/support/all_servers.sh -C -k “umount /media/cdrom" Delete the ISO from all appliances. If you use WinCollect agents version 7.2.6 or later, you must reinstall the SFS file on the QRadar Console. This is due to issues where the ISO replaces the SFS on the Console with WinCollect 7.2.5 as described here: APAR IV96364 . To install the latest WinCollect SFS on the Console, see the WinCollect release notes: WinCollect 7.2.7 Release Notes . Review any static routes or customized routing. As mentioned in the administrator notes, all routes were removed and will need to be reconfigured after the upgrade completes. Review any iptable rules that are configured to see if the interface names that have changed in QRadar 7.3.1 due to the Red Hat Enterprise 7 operating system updates affect them. Update any iptables rules that use Red Hat 6 interface naming conventions.









Resolved issues for QRadar 7.3.1 Patch 3

Some APAR links in the following table might take 24 hours to display properly after a software release is posted to IBM Fix Central. Several of these issues were fixed in 7.2.8 and 7.3.0 versions and exist in the 7.3.1 Patch 3 software update. For this reason, some APARs state that they were fixed in earlier releases, but are displayed as part of the QRadar 7.3.1 Patch 3 resolved issues list.
