ZMCS Maps
number in the range 1 through 100. For more information, see the DSM/Tape 
Catalog Operator Interface (MEDIACOM) Manual.
ZUNLOAD
corresponds to the UNLOAD parameter of the MEDIACOM LABEL TAPEVOLUME 
command. ZUNLOAD (ON or OFF) denotes what happens to the tape after this 
command is finished. 
•
ON (default) means the tape is unloaded.
•
OFF means the tape stays loaded and online.
ZPROMPT
corresponds to the PROMPT parameter of the MEDIACOM LABEL TAPEVOLUME 
command. ZPROMPT denotes when the tape drive begins checking (polling) that a 
tape is mounted.
•
ON (default) means polling does not begin until you manually start it. This 
message is sent to the current default output file:
\node.$tape: not ready:
When the tape is mounted, processing continues.
•
OFF means polling is done immediately by the tape drive. This message is 
sent to the current default output file:
\node.$tape: not ready -- beginning to poll
When the tape is mounted, processing continues.
ZOVERRIDE
corresponds to the OVERRIDE parameter of the MEDIACOM LABEL 
TAPEVOLUME command. ZOVERRIDE (ON or OFF) denotes to what extent the 
system search space is checked for a duplicate tape name and whether to write 
over an existing tape label. 
ON catalogs the tape even if the entire system search space cannot be checked 
for a duplicate tape name. However, what is available of the system search space 
is checked. If a duplicate name is found, the tape is not cataloged. Be cautious 
when using this option because there is a chance of cataloging a duplicate name.
Also, any existing label on the tape is written over by LABEL TAPEVOLUME with 
the new label.
OFF (default) catalogs the tape when no duplicate name is found in the entire 
system search space. If the entire system search space is not available, the 
LABEL TAPEVOLUME command does not execute.
If the tape already has a label, LABEL TAPEVOLUME does not execute even if no 
duplicate tape name is in the catalog.
