Installations from the recovery partition

When you install IBM QRadar products, the installer (ISO image) is copied to the recovery partition. From this partition, you can reinstall QRadar products. Your system is restored back to the default configuration. Your current configuration and data files are overwritten

When you restart your QRadar appliance, an option to reinstall the software is displayed. If you do not respond to the prompt within 5 seconds, the system continues to start as normal. Your configuration and data files are maintained. If you choose the reinstall option, a warning message is displayed and you must confirm that you want to reinstall.

The warning message states that you can retain the data on the appliance. This data includes events and flows. Selecting the retain option backs up the data before the reinstallation, and restores the data after installation completes. If the retain option is not available, the partition where the data resides may not be available, and it is not possible to back up and restore the data. The absence of the retain option can indicate a hard disk failure. Contact Customer Support if the retain option is not available.
