SPXTAPE
The activities of each SPXTAPE command are recorded in at least two spool files:
a command summary log and one or more volume logs. These logs are created by
the SPXTAPE DUMP, LOAD, and SCAN commands.
Both logs have the same routing and disposition as the virtual console of the user
who enters the SPXTAPE command (or causes the SPXTAPE operation to begin).
If you enter the command spool cons * before you enter the SPXTAPE command,
all logs are sent to your virtual reader. If you want to change the spooling of your
console, you should do it before you enter the SPXTAPE command, or the logs
may be sent to different destinations.
Command Summary Log: The command summary log records the progress and
status of an SPXTAPE DUMP, LOAD, or SCAN operation. Most command
responses, as well as any error messages, are recorded in this log. A new
command summary log is created for each SPXTAPE DUMP, LOAD, or SCAN
command, unless the command is appended to a previous SPXTAPE command.
Each command summary log has a unique name. The file name and file type have
the following format:
aabbcccc hhmmss
aa is the month the SPXTAPE command is issued.
bb is the day the SPXTAPE command is issued.
cccc
is the SPXTAPE operation: DUMP, LOAD, or SCAN.
hh is the hour the SPXTAPE command is issued.
mm
is the minute the SPXTAPE command is issued.
ss is the second the SPXTAPE command is issued.
The command summary log contains a header (response 1) for the command that
creates the log. If the command that creates the log is issued with the APPEND
operand, a header is also written in the log for each appended command.
Volume Log:
1464 z/VM: CP Commands and Utilities Reference
The volume log records information about the files processed by an SPXTAPE
DUMP, LOAD, or SCAN command that are associated with a particular tape
volume. There is one volume log for each tape volume for each SPXTAPE
command. For example, if you use the SPXTAPE DUMP command with the LEAVE
operand 10 times to save files on a single tape volume, 10 volume logs are
created. If you use a single SPXTAPE DUMP command to dump files to 10 different
tape volumes (and all 10 are actually used), 10 volume logs are created.
The volume log is a record of what is dumped to, loaded from, or scanned on a
tape volume. For an SPXTAPE LOAD operation, the volume log may record more
than what is actually loaded from the tape. A failure or operator action that occurs
after a file has been read from the tape and logged (such as spool space being
exhausted, or the SPXTAPE CANCEL command being used against the tape drive)
may prevent the file from being stored in the spooling system. The files that are not
loaded successfully are reported with messages sent to the SPXTAPE user and
recorded in the command summary log.
