Dell NetWorker 19.9 Administration Guide

Edit the st.conf file only if one of the following conditions apply:

• The NetWorker configuration includes DDS.
• Solaris st does not support a tape drive that is configured on a Solaris host.

To determine if the Solaris st tape driver supports a tape drive, perform the following steps:

1. Use the mt command to load a tape in the drive. For example, with the tape device file 0cbn, the type: mt -f /dev/rmt/0cbn status
   • If the output of the mt command includes the line SCSI tape drive or appears similar to the following, the st tape driver uses generic settings, which do not support the tape drive:

     mt -f /dev/rmt/4cbn status
     Vendor 'IBM     ' Product 'ULT3580-TD2    ' tape drive:
     sense key(0x6)= Unit Attention   residual= 0   
retries= 0 file no= 0   block no= 0

     Tape operations may appear to work in NetWorker but you may run into problems when you try to recover saved data.

   • If the output of the mt command appears similar to the following, the st tape driver recognizes the drive and uses the correct internal settings to manage the drive:

     mt -f /dev/rmt/0cbn status
     HP Ultrium LTO tape drive:
     sense key(0x0)= No Additional Sense   residual= 0   
retries= 0 file no= 0   block no= 0

     In this configuration, you must only edit the st.conf file when you use the drive in a DDS configuration.
