I am trying to use a 4mm drive to backup my tsm database.

Here is my devconfig:

/* Device Configuration */
DEFINE DEVCLASS 4MM DEVTYPE=4MM FORMAT=DDS3 ESTCAPACITY=12582912K
MOUNTLIMIT=1 M
OUNTWAIT=2 MOUNTRETENTION=2 PREFIX=ADSM LIBRARY=MANUAL_LIBRARY
SET SERVERNAME PFPC_TSMTEST
DEFINE LIBRARY MANUAL_LIBRARY LIBTYPE=MANUAL
DEFINE DRIVE MANUAL_LIBRARY 4MMTSMDRIVE DEVICE=/dev/rmt4 ONLINE=Yes

Here is the activity log:
