Setup Stand-Alone Device

The Setup Stand-Alone Device selection allows a drive to be set up in stand-alone mode. This mode is used to allow a host to run software that, in general, is in complete control of the drive. The software needs to be attached to a tape drive that is physically or virtually inside a library. The software is not aware that the drive is in the library, and it cannot issue commands to mount and demount volumes in that library.

Stand-Alone drive is supported for virtual drives within a Virtual Tape Server with the exception of the ªMount from Input Stationº feature.

Stand-Alone drive is not supported for the physical drives associated with a Virtual Tape Server.

To assist the host software, stand-alone mode is used by the library to automatically load and unload one or more speci®c cartridges into a speci®c drive, without any host software interaction. The host software allows the operator to specify which cartridge is mounted and demounted into a drive by using the library manager console. Figure 114 on page 181 shows the Setup Stand-Alone Device Pop-Up Window.

Note: The drive that is being used in stand-alone mode should be varied off from all hosts except the host that is being used in this special mode. This will prevent unwanted interaction from all hosts except the desired one.
