Specify tape devices as symbolic links

You can specify the values of LTAPEDEV and TAPEDEV as symbolic links. Using symbolic links enables you to switch to other tape or tape-compatible devices without changing the path name in the onconfig file. For example, you can specify the following symbolic link for tape device /dev/rst0:

ln -s /dev/rst0 /dbfiles/logtape

When you set the LTAPEDEV configuration parameter, as the following example shows, you can switch to a different device without changing the LTAPEDEV parameter:

LTAPEDEV /dbfiles/logtape

You only need to change the symbolic link, as the following example shows:

ln -s /usr/backups /dbfiles/logtape
