Cause. When a tape file on an IBM labeled tape was opened for output, the requested
tape volume was not mounted.
Effect. The operation waits for the tape to be mounted.
Recovery. The request is suspended until one of the following actions is taken:

Abort the operation with the MEDIACOM REJECT command, if the requested tape
volume is not available. $ZSVR generates the action-completion message ZTAP-
EVT-REJECTMOUNT (651).

Mount the requested IBM tape volume on the tape device indicated by ZTAP-TKN-
DEV-NAME, if this token is specified in the event message. Otherwise, mount the
requested IBM tape volume on any free tape device that satisfies the density
request indicated by ZTAP-TKN-DENSITY, if this token is specified in the event
message. $ZSVR generates the action-completion message ZTAP-EVT-
ACCEPTMOUNT (648).

Leave the request suspended until one of the above actions is taken. If the
processor of the requester goes down while the request is suspended, $ZSVR
generates the action-completion message ZTAP-EVT-CANCELMOUNT (649).
ZEMS-TKN-TEXT Standard EMS token that contains the message text. See
Event Management Service (EMS) Standard Definitions
on
page 9-9.
ZTAP-TKN-TAPE-VOLUME Subject token that specifies the volume serial number of
the requested volume.
Token Description
ZTAP-TKN-REEL Reel number, if this operation is a multivolume operation.
ZTAP-TKN-DENSITY Tape density. Values are ZSPI-VAL-800BPI, ZSPI-VAL-
1600BPI, and ZSPI-VAL-6250BPI.
ZTAP-TKN-DEV-NAME Subject token that specifies the tape drive device name in
the system. This token is present if the request is for a
continuation volume of a multivolume operation or if the
user requested a specific device.
ZEMS-TKN-TEXT Up to 80 bytes of comments that were specified with the
DEFINE attribute MOUNTMSG. These comments provide
