This command is a vital tool within the VMware ESXi command-line interface (esxcli). It retrieves a comprehensive inventory of Virtual Installation Bundles (VIBs) currently installed on an ESXi host. The output includes the name, version, vendor, acceptance level, and install date of each VIB, offering a detailed snapshot of the software components present on the system. For example, executing this command will produce a list of all the drivers, patches, and other software packages installed on the ESXi host.
Understanding the installed VIBs is crucial for several reasons. Firstly, it enables administrators to verify that critical security patches have been successfully applied. Secondly, it aids in troubleshooting compatibility issues between different software components. The command also provides a historical context of software changes on the host, making it easier to identify when a particular component was installed or updated. This information is invaluable for maintaining system stability and security.
