Unload This switch is used to rewind and unload the tape cartridge, ending

with the tape cartridge ejected and retrievable.

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

Detailed instructions are included in this manual where needed.
