When stand-alone dump output is sent to a 3480, 3490, or 3590 magnetic
tape subsystem, stand-alone dump uses the subsystem's eight-character
message display to inform and prompt the operator. The leftmost position
on the message display indicates a requested operator action. The
eighth position (rightmost) gives additional information.
In the messages listed below, alternating indicates that there
are two messages which are flashing on the display, one after the
other. A blinking message is one message that is repeated on the display.
The stand-alone dump messages that can appear on the display are:
- Dvolser (alternating)
- MSADMP#U
- Informs the operator that a labeled tape has been rejected and
a new tape must be mounted.
- MSADMP#U (blinking)
- Requests that the operator mount a new tape.
- RSADMP#U (blinking)
- Indicates that the stand-alone dump program has finished writing
to the tape.
- RSADMP# (alternating)
- MSADMP#U
- Informs the operator that an end-of-reel condition has occurred
and a new tape must be mounted.
- SADMP# (blinking)
- Indicates that the tape is in use by stand-alone dump.
- SADMP# (alternating)
- NTRDY
- Informs the operator that some type of intervention is required.
The symbols used in the messages are:
- #
- A variable indicating the actual number of cartridges mounted
for stand-alone dump. It is a decimal digit starting at 1 and increasing
by 1 after each end-of-cartridge condition. When the # value exceeds
9, it is reset to 0.
- D
- Demount the tape and retain it for further system use, for example
as a scratch tape. Stand-alone dump does not write on the tape.
- M
- Mount a new tape.
- R
- Demount the tape and retain it for future stand-alone dump use.
- U
- The new tape should not be file-protected.
- volser
- A variable indicating the volume serial number on the existing
tape label.
