CPI installer shows an unsupported kernel error on RHEL 9.4 and blocks InfoScale installation (4189070, 4189127)

This issue occurs when try to install InfoScale using CPI on RHEL 9.4 systems where the RHEL kernel version is 5.14.0.427.26.1.el9_4.x86_64. The issue happens on systems that do not have direct access to a public network.

When you run CPI to install InfoScale, the installer displays an unsupported kernel error during platform version checks.

The following message is displayed:

CPI ERROR V-9-40-1449 Kernel Release 5.14.0-427.26.1.el9_4.x86_64 is 
detected on bait-rhel9vm1, which is not supported for this product.

installer log files and summary file are saved at:
/opt/VRTS/install/logs/installer-install-<datetimestamp>

This error occurs because of an incorrect entry in the supported platform release matrix that is stored locally in the installation RPM. CPI uses the platform matrix as a reference for performing system checks before InfoScale installation.

If the system has internet connectivity, CPI automatically pulls the latest updated matrix from SORT. But in cases where the system does not have public network access, CPI uses the matrix file stored locally in the installer RPM. Since the local file has the erroneous entry, CPI checks fail and the installation is blocked.

Workaround: Enable public network access for the system and then run the installer so that CPI can fetch the latest platform support matrix from the SORT website.

If network access is not available, you can edit the locally stored kernel padv JSON file and then run the installer again.

  1. Locate the kernel padv json file in the installation RPM:

    <installRPM>/scripts/CPIP/Rel/Matrix/kernel_padv.json

  2. Open the file in an editor and search for the kernel 5.14.0.427.26.1 entry.

    Then change the following value: “level”: “Update 3” to “level”: “Update 4”.

    The entries should appear as follows:

   "5.14.0-427.26.1": {
   "padv": "rhel9_x86_64",
   "level": "Update 4",
   "gaDate": "2024-08-13",
   "platform": "Linux"
   }

  1. Save and close the file and then run the installation again.
