Restarting Backup and Verifying Tape Drive Status
1 In the CACS XTerm window in which you stopped
ontape
(see
“Stopping Logical Log Backup and Replacing Tapes” on page 97), restart
logical log backup by entering
ontape -c
.
Informix responds:
Performing continuous backup of logical logs.
Please mount tape 1 on /dev/rmt/1 and press Return to continue.
2 Press ENTER.
Informix begins backing up all the currently full log files and marks them
as once again available for logging. As long as the process continues to
run, it backs up each log as it becomes full and marks it as available again.
You can minimize this XTerm window if you want, but don’t quit. If you
quit this XTerm window, the
ontape
process stops, and your logical logs
are no longer being backed up.
3 In a new XTerm window, check the status of the logical log backup tape
device by entering
mt -f /dev/rmt/1 status
.
The system should indicate that the tape drive is in use, as shown in
Figure 4-5.

4 Check the archive tape device by entering
mt -f /dev/rmt/0 status
.
The system should indicate that the tape drive is at the load point, as
shown in Figure 4-6.

This concludes the routine daily maintenance. You may want to check logical
logging status again later (by entering
onstat -l
), after Informix has had time
to fill a logical log file, to confirm that the logs are being backed up.
