1.INDETIFY YOUR TAPE BACKUP UNIT
RedHat Linux supports many different kinds of tape devices.
Typically, SCSI tape devices will be named
/dev/st0, /dev/st1, etc.
IDE tape devices will be named
/dev/ht0, /dev/ht1, etc.
If the device name has an “n” in front of it, like /dev/nst0 for example, then it is a “No rewind” device. The device will not rewind automatically after a utility like dump or tar is finished writing to it.
Identify the TBU in your system with the following command:
# cat proc/scsi/scsi
Notice the information that this file contains: Vendor, Model, Firmware revision, and access type.
2.CONTROLLING THE TAPE DEVICE
The mt utility can be used to control the tape device.
Mt is installed with package mt-st-0.5b-10.src.spm.
# mt
usage: mt [-v] [-h] [ -f device ] command [ count ]
You can use the –f switch to specify a tape device. For example, to eject a scsi tape from your tape backup unit, type the following command:
