Backups with HP Data Protector may fail with the following error:
First, attempt to perform a manual clean of the drive, then try re-running the backup. If it fails again, power-cycle/reboot the drive/library.
If the error still persists, start HP Library and Tape Tools and run a drive assessment. You'll need to load a tape into the drive first. If the test fails (i.e. it returns an error code, such as internal error), call HP for support.
No_Light means there's no link on the port. Usually this indicates a problem with the physical wiring, either a faulty cable, or the TX/RX have been swapped.
No_Sync means there's a link on the port (so technically, wiring is okay), but there's a problem with the actual communication. The most common problem is a mismatch in speed on the switch port and the HBA on the other side. Your best bet would be to set the port's speed (temporarily) to auto-negotiate and see what speed is selected. If this does not work, try manually setting the port fixed to lower speeds.
Before installing ROK licenses on your virtual machines on VMware, be sure to allow SMBios reflection of the host to the VM's. Otherwise, authorization will fail with a This system is unsupported message.

SMBIOS.reflectHost = TRUE
If you have an HP laptop with an unknown device with hardware-id HPQ6001, it's the HP wireless button driver. Apparently some models on their support website lack this driver in the download list (it was the case for a HP Envy Touchsmart 1230eb).
