Example of creating a no rewind device file

This topic provides an example of how to create a no rewind device file on AIX for NetBackup. Assume the device files for the wanted SCSI 8-mm tape drive (controller 1, SCSI ID 5) do not exist.

To create a no rewind device file for SCSI ID 5

  1. Determine the logical identifier for the SCSI controller as follows:
    /usr/sbin/lsdev -C -c adapter | grep SCSI

    The following output shows that scsi0 is the logical name for SCSI controller 1:

    scsi0  Available 00-01    SCSI I/O Controller
  2. Determine if the device files exist for any device at SCSI ID 5.
    /usr/sbin/lsdev -C -s scsi

    The following output shows that some device files exist for tape and disk. However, a device files does not exist for the 8-mm tape drive at controller 1 (scsi0) and SCSI ID 5 (5,0):

    hdisk0  Available 00-01-00-0,0 400 MB SCSI Disk Drive
hdisk1  Available 00-01-00-1,0 400 MB SCSI Disk Drive
rmt0    Available 00-01-00-3,0 Other SCSI Tape Drive
  3. Create the device file by using the following command:
    mkdev -c tape -t ost -s scsi -p scsi0 -w 5,0
  4. Display the device files by issuing the following command:
    /usr/sbin/lsdev -C -s scsi
hdisk0  Available 00-01-00-0,0 400 MB SCSI Disk Drive
hdisk1  Available 00-01-00-1,0 400 MB SCSI Disk Drive
rmt0    Available 00-01-00-3,0 Other SCSI Tape Drive
rmt1    Available 00-01-00-5,0 Other SCSI Tape Drive
  5. To ensure that the tape device is configured for variable-mode and extended file marks, use the following commands:
    chdev -l rmt1 -a block_size=0
chdev -l rmt1 -a extfm=yes
  6. To configure the drive manually in NetBackup, enter the following device file pathname:
    /dev/rmt1.1
