Error Code Cause and Action
Problems with Writing Data
If the problem occurred while the tape drive was writing data to the tape, retry the operation with
a different cartridge:
v If the operation succeeds, the original cartridge was defective. Copy data from the defective
cartridge and discard it.
v If the operation fails and another tape drive is available, insert the cartridge into the other unit
and retry the operation.
– If the operation fails, discard the defective cartridge.
– If the operation succeeds, insert a scratch data cartridge into the first unit and run “Function
code 1: Run drive diagnostics” on page 24.
- If the diagnostic tests fail, replace the tape drive.
- If the diagnostic tests succeed, the error was temporary.
v If the operation fails and another tape drive is not available, insert a scratch data cartridge into
the unit and run “Function code 1: Run drive diagnostics” on page 24.
– If the diagnostic tests fail, replace the tape drive.
– If the diagnostic tests succeed, discard the cartridge.
If the problem occurs with multiple tape cartridges, run “Function code 1: Run drive diagnostics”
on page 24:
v If the diagnostic tests fail, replace the tape drive.
v If the diagnostic tests succeed, run“Function code H: Test head” on page 31.
– If the diagnostic test fails, replace the tape drive.
– If the diagnostic test succeeds, replace the cartridges that caused the problem.
The error code clears when you remove the tape cartridge or place the tape drive in Maintenance
mode.
Problems with Reading Data
If the problem occurred while the tape drive was reading data from the tape, complete one of
these procedures:
v If another tape drive is available, insert the cartridge into the other unit and retry the operation:
– If the operation fails, discard the defective cartridge.
– If the operation succeeds, insert a scratch data cartridge into the first unit and run “Function
code 1: Run drive diagnostics” on page 24:
- If the diagnostic test fails, replace the tape drive.
- If the diagnostic test succeeds, the error was temporary.
v If another tape drive is not available, insert a scratch data cartridge into the unit and run
“Function code 1: Run drive diagnostics” on page 24:
– If the diagnostic test fails, replace the tape drive.
– If the diagnostic test succeeds, discard the cartridge.
If the problem occurs with multiple tape cartridges, run “Function code 1: Run drive diagnostics”
on page 24.
v If the diagnostic test fails, replace the tape drive.
v If the diagnostic test succeeds, run “Function code H: Test head” on page 31.
– If the diagnostic test fails, replace the tape drive.
– If the diagnostic test succeeds, replace the cartridges that caused the problem.
The error code clears when you remove the tape cartridge or place the tape drive in Maintenance
mode.
