Posted: 08 Jan, 2008
TapeAlert is a standard for devices to report diagnostic messages to the controlling application. A "No TapeAlert Messages" response is a good thing.

There are three severity levels of tape alert messages:

  • Informational (for example, you may have tried to load a cartridge type that is not supported)
  • Warning (for example, a hardware failure is predicted)
  • Critical (for example, there is a problem with the tape and your data is at risk)

TapeAlert Messages

These TapeAlert messages are from table A.1 of the ANSI T10 SSC-2 project.  You can find the complete PDF by visiting INCTIS Website.

Key:

O = Optional
M = Mandatory
C = Critial
W = Warning
I = Informational

Code Flag Type Flag Type Recommended User Action Probable Cause

01h

Read Warning O W The tape drive is having problems reading data. No data has been lost, but there has been a reduction in the performance of the tape. The drive is having severe trouble reading.
02h Write Warning O W The tape drive is having problems reading data. No data has been lost, but there has been a reduction in the performance of the tape. The drive is having severe trouble writing.
03h Hard Error M W The operation has stopped because an error has occurred while reading or writing data that the drive cannot correct. The drive had a hard read or write error.
04h Media M C

Your data is at risk:
1. Copy any data you require from this tape.
2. Do not use this tape again.
3. Restart the operation with a different tape.

Media can no longer be written/read, or performance is severely degraded.
05h Read Failure M C The tape is damaged or the drive is faulty. Call the tape drive supplier help line. The drive can no longer read data from the tape.
06h Write Failure M C

The tape is from a faulty batch or the tape drive is faulty:
1. Use a good tape to test the drive.
2. If the problem persists, call the tape drive supplier help line.

The drive can no longer write data to the tape.
07h Media Life O W

The tape cartridge has reached the end of its calculated useful life:
1. Copy any data you need to another tape.
2. Discard the old tape.

The media has exceeded its specified life.
08h Not Data Grade O W The cartridge is not data-grade. Any data you write to the tape is at risk. Replace the cartridge with a data-grade tape. The drive has not been able to read the MRS stripes.
09h Write Protect O C You are trying to write to a write protected cartridge. Remove the write protection or use another tape. Write command is attempted to a write protected tape.
0Ah No Removal O I You cannot eject the cartridge because the tape drive is in use. Wait until the operation is complete before ejecting the cartridge. Manual or software unload attempted when prevent media removal is on.
0Bh Cleaning Media O I The tape in the drive is a cleaning cartridge. Cleaning tape loaded into drive.
0Ch Unsupported Format O I You have tried to load a cartridge of a type that is not supported by this drive. Attempted load of unsupported tape format (e.g., DDS2 in DDS1 drive).
