Dismount Sequence; Determining When The Library Is Not In Automated Mode - Sun Microsystems StorageTek SL500 User Manual

Automated Mode of Operation

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.
