In a previous article (see https://www.data-protector.org/wordpress/2013/05/persistent-binding-hp-lto-tape-drives-windows/) I reported about “tape persistence” for Windows.
In general there is noch change to adopt this for Windows 2012 and the registry keys are the same. However, a requirement is to activate “Target Persistent Binding” for the Fibre Channel HBA. In case of a QLogic adapter you may use the tool “QConvergeConsole” (SANSurfer) for the configuration. For Emulex (HBAAnywhere) the configuration is nearly the same. After configuration and activation on the HBA, adding the registry keys and a final reboot, the tape drives and the changer can be used “persistent”. Comment: all tested with HP libraries/drives.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hplto] "AutoRun"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Tape] "Persistence"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MChgr] "Persistence"=dword:00000001
