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 “Mount from Input Station” 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 specific cartridges into a specific 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.
