About legacy tape drive device files
NetBackup requires the /dev/rmt device files to configure tape drives.
The device file names have the following format:
/dev/rmt/c#t#d#BESTnb
The following describe the device file names:
c# is the card instance number.
t# is the SCSI ID.
d# is the device LUN.
BEST indicates the highest density format and data compression the device supports.
n indicates no rewind on close.
b indicates Berkeley-style close.
The following are examples of tape drive device files:
/dev/rmt/c7t0d0BESTnb /dev/rmt/c7t1d0BESTnb /dev/rmt/c7t4d0BESTnb /dev/rmt/c7t5d0BESTnb
