Unload This switch is used to rewind and unload the tape cartridge, ending
with the tape cartridge ejected and retrievable.
If Unload is pressed during a write operation, the drive attempts to write
the remaining data before it unloads. A display of UnWr xxxx
(meaning Unwritten Data, where xxxx is a fault symptom code) means
that the attempt failed and some data remains unwritten to tape.
Pressing Unload switch again will cause loss of this data. For the host to
save the unwritten data, the operator must issue the following
command sequence before pressing
Unload again:
• In the SCSI environment: Recover Buffer Data
• In the Fibre Channel environment: Recover Buffer Data
Menu This switch is used to enter and exit the menu system and during
navigation of submenus. The menu system allows you to reconfigure
the drive or do special operations.
When in normal operation mode, pressing this switch will take you to
the Online/Offline top menu. To make changes in drive configurations
or do special operations, the drive must be offline, but if you only want
to view drive configurations, it may remain online. Use the
Select
switch to change modes.
When in a main menu, with the drive offline, pressing Menu will step
you through the other main menus, bypassing the submenus (to enter
submenus, see
Select Switch).
When in a submenu, pressing Menu will step you through the other
submenus or through different sections in a submenu.
The most important main menu selections are:
• Offline/online state
• Drive configuration choices
• Special drive operations
• Main exit
