If the UEFI Secure Boot option is enabled on the Linux computer, the kernel performs a signature check on the Commvault driver modules before they are installed.
To use the Commvault driver modules, enroll the Commvault keys with the UEFI MOK (Machine Owner Key) list so that the kernel recognizes the signature of the Commvault driver modules. Otherwise, the Commvault driver modules cannot be installed.
For more information about enrolling Commvault keys with the UEFI MOK list, see Enrolling Commvault Keys with the UEFI MOK List.
