Dismounting a Cartridge from a T9840 Drive
To unload the cartridge from a T9840 drive:
1. Ensure that the drive is not selected.
CAUTION:
Loss of data : Pressing the Unload switch during a write operation
causes the drive to try to write the remaining data before the tape
unloads. An operator display of
“UnWrxxxx” (unwritten data, where xxxx
is the fault symptom code) means the write failed and some data is not
written to the tape.
2. Press the Unload switch.
One of the following conditions can occur:
• After the tape rewinds, the cartridge ejects from the drive. Remove the cartridge
from the drive and place it outside of the LSM.
• The cartridge fails to eject after the tape rewinds. Refer to the T9840 Tape Drive User’s
Reference Manual to correct this condition.
• If the Unload switch is pressed during a write operation, the drive tries to write the
remaining data before the cartridge unloads. If the
UnWr xxxx
(Unwritten Data)
message displays, where
xxxx
is the fault symptom code, the attempt failed and
some data remains unwritten to the tape. For more information about recovering
from an Unwritten Data condition, refer to the
T9840 Tape Drive User’s Reference
Manual .
