Known issues in QRadar 7.5.0

App Host cannot communicate with Console correctly when connection is firewalled

If your network connection is behind a firewall, the App Host is unable to communicate with your Console.

To workaround this issue, remove encryption from the App Host and open the following ports on any firewall between your App Host and Console: 514, 443, 5000, 9000.

To review information on these ports, see QRadar port usage.

Apps might go down during base image upgrade

After you install QRadar 7.5.0, your applications might go down temporarily while they are being upgraded to the latest base image.

'9804.install' fails when managed host removed from deployment

If you remove a managed host from deployment prior to upgrading to QRadar 7.5.0, an error message appears.

For more information, see IJ36269.

Patch pre-test can fail when WinCollect 7.3.XX installed

If you have WinCollect 7.3.xx installed when you upgrade to QRadar 7.5.0, the QRadar patch pre-test can fail when the check_yum.sh pre-test does not clean out the old yum cache.

For more information, see IJ32896.

Issue adding Data Nodes to a cluster

When adding a Data Node to a cluster, they must either all be encrypted, or all be unencrypted. You cannot add both encrypted and unencrypted Data Nodes to the same cluster.

About this installation

These instructions are intended to assist you when you install QRadar 7.5.0 Update Package 4 by using an ISO file. This ISO can install QRadar, QRadar Risk Manager, QRadar Vulnerability Manager, and QRadar Network Insights products to version 7.5.0 Update Package 4.

See QRadar: Software update check list for administrators for a list of steps to review before you update your QRadar deployment.

Part 1. Installing the QRadar 7.5.0 ISO Update Package 4

These instructions guide you through the process of installing QRadar 7.5.0 Update Package 4.

Important: You can use the verify signature tool to validate the integrity of your downloads from IBM Fix Central. For more information, see How to verify downloads from IBM Fix Central are trusted and code signed.

Procedure

Download the QRadar 7.5.0 Update Package 4 ISO (5.31 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=7.5.0&platform=Linux&function=fixId&fixids=7.5.0.4-QRADAR-QRFULL-20221129155237&includeRequisites=1&includeSupersedes=0&downloadMethod=http&source=fc

IMPORTANT: QRadar Incident Forensics uses a unique ISO file to install 7.5.0 Update Package 4. See the Fix Central page for that product to download the correct file.
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: Installing QRadar 7.5.0 Update Package 4 should take approximately 2 hours on a Console appliance.
Wait for the Console primary update to complete.

Note: In QRadar 7.3.1 Patch 6, a kernel update was introduced to address issues with appliances failing to log in or list unit files. These issues could prevent the appliance from rebooting. This new kernel does not take effect until the appliance is rebooted. You might need to reboot your system manually for the kernel update to take effect.

To work around this issue, you must perform a restart of the appliance. To do this, type the reboot command, or use Integrated Management Module (IMM).

Results

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

Part 2. 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 latest, 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 at WinCollect 101.
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 7.5.0 due to the Red Hat Enterprise 7 operating system updates affect them. Update any iptables rules that use Red Hat 6 interface naming conventions.
