Use of DLTSage WORM Tapes
DLT-S4 Interface Reference Guide 349
• Sense Key — Illegal Request (05)
•
Parameter List Error, Invalid Field (26/00)
•The
REQUEST SENSE data will point to the attribute (0x0408) field
that you are incorrectly trying to modify.
If you have a standard DLTtape S4 cartridge and there is an error in the
process of converting it to a DLTSage WORM tape, the following sense
data will be presented:
•
Sense Key — Medium Error (03)
•
Additional Sense Code — DLTWorm Creation Error (0x83)
•
Additional Sense Code Qualifiers:
• DLTWorm Erase Failed (0x90)
• DLTWorm Rewind Failed (0x91)
• DLTWorm Read Failed (0x92)
• DLTWorm Creation Invalid (0x93)
If a DLTtape S4 cartridge fails DLTSage WORM initialization, the
application needs to report the above sense data. If failures 0x90, 0x91, or
0x92 occur, the initialization of the DLTSage WORM tape was not
successful. If failure 0x93 occurs, the cartridge is either the wrong type or
has data on it. For all failures, the best recovery is to degauss the tape and
try the operation again. If DLTSage WORM initialization fails a second
time, the tape should be considered defective.
Determining if the Integrity
of the DLTSage WORM
Cartridge has been
Compromised
1
The DLTSage WORM firmware will report the WORM Medium Integrity
Check Failed Tape Alert (0x3B) if the integrity of the DLTSage WORM
cartridge has been compromised. The drive will come ready but will
respond to all write commands with the following sense:
•
Sense Key — Medium Error (03)
•
Additional Sense Code — Format Corrupted (0x31)
•
Additional Sense Code Qualifiers — DLTWorm Corrupted (0x94)
