For reasons of operational safety, all IT technical systems of the HRZ are subject to maintenance. A distinction must be made between regular maintenance and security-critical updates:
Security-critical updates must therefore always be installed immediately. Since not all systems are available in a clustered, fail-safe form, this necessarily leads to interruptions in operation, even during the semester, which unfortunately cannot be avoided.
Regular maintenance is installed at fixed times. Here, too, not all systems are available in a clustered, fail-safe form, and this also leads to interruptions in operation.
Note: Currently, only the BIOS/UEFI, firmware or other Dell Security Advisory updates are to be carried out via Dell Command | Update. The following configuration instructions have been adapted accordingly. Changes are possible at any time.
