This topic provides general information about troubleshooting common
virtual tape problems.
Typically, when an error occurs with virtual tape storage, the operation
stops and you receive an inquiry or escape message. The message indicates
that there is something wrong with the volume being processed and provides
recovery instructions. Follow the instructions to recover from the inquiry
or escape message.
The most common inquiry and escape messages that occur with virtual tape
storage are:
Inquiry messages
- CPA4262 - Volume &5 on device &4 is write protected (C R).
- CPA6745 - Volume on device &4 is write protected (C R).
Escape messages

- CPF41B4 - Virtual tape volume not available.
- CPF41B5 - Virtual tape volume not found.
- CPF67F5 - Duplicate cartridge or virtual volume name found.
- CPF4373 - End of Media on Device. This message is sent when the storage
threshold of the ASP containing the virtual tape volume exceeds 95%, or when
the maximum storage allowed threshold of the user profile that owns the virtual
tape is exceeded and additional storage cannot be allocated to
continue the output operation.
