Responding To Messages And Requests - HP Guardian User Manual

Using Labeled Tapes
This command also displays outstanding tape mount and drive-usage requests and puts
the specified terminal in console mode. If you do not specify a device, the current
terminal is used for tape mount and drive-usage requests.
Only one terminal in a system can be in console mode at a time. If you enter the
CONSOLE or ALTER CONSOLE command when another terminal is already in
console mode, an error message is displayed.
Use the TACL STATUS command to list the name of the terminal running the process
(cpu,pin):
> STATUS cpu,pin
To terminate console mode with MEDIACOM, enter the ALTER CONSOLE, RESET
DEVICE command at the terminal you have designated as the console.
Example
To use MEDIACOM to view the messages sent from $ZSVR on your terminal, log on
as a super-group user (255,n) and enter:
> MEDIACOM
MEDIACOM - T6028D20 (01JUN93)

Responding to Messages and Requests

Labeled-tape operation messages fall into these categories:
$ZSVR error and status messages
Tape process error and warning messages
Labeled tape and scratch tape mount requests
Tape drive-usage requests
Operator attention requests
All labeled-tape messages that have a sequence number require some action from you.
Sequence numbers are used in the MEDIACOM ACCEPT TAPEMOUNT and REJECT
TAPEMOUNT commands. Labeled-tape messages are described in the Operator
Messages Manual.
