Cause. This event message is sent when either:

An operation requests an ANSI labeled scratch tape.

An output file requires more than one volume, but not enough volume serial
numbers were specified in the DEFINE entry.
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 a scratch ANSI
tape volume is not available. $ZSVR generates the action-completion message
ZTAP-EVT-REJECTMOUNT (651).

Mount a scratch ANSI tape volume on the tape device indicated by ZTAP-TKN-
DEV-NAME, if this token is specified in the event message. Otherwise, mount a
scratch ANSI 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.
