Responding to Tape Drive-Usage Requests
When you receive a tape drive-usage (tape mount) request, you first view the request
using MEDIACOM, then respond to it by entering either the MEDIACOM ACCEPT or
REJECT TAPEMOUNT command.
When you get a request to use a particular tape drive, you must accept or reject the
request. The job making such a request cannot open the drive without your permission.
