Dismount Sequence
A simplified dismount sequence involves the following steps:
1. A host requests that a specific VOLID be dismounted from a drive.
2. The library controller transmits to the host that the VOLID is located in the drive and
the library is available to satisfy the dismount request.
3. The library assumes responsibility for the dismount.
4. The host command is translated by the library controller into mechanical commands
for the HandBot.
5. The cartridge is taken from the drive and placed into its home cell.
6. The library returns status to the host that the dismount operation is completed.
Determining When the Library is Not in Automated
Mode
The library is not in automated mode when it is not able to accept host requests. The
following conditions indicate that the library is not in automated mode:
■
A library access door is open.
■
The HandBot does not automatically mount and dismount cartridges.
■
The device tree in the SL Console indicates that there is a problem with the library.
