If character special files are to be used, you must use the pdfmkfs command to make an initial setting that the HiRDB file system area will use character special files. If the character special files are symbolic links, specify the names of the links.
Modify the owner and access privileges of the file system area before making the initial setting. For details about the modifications, see 2.3.6(5) Change the owner and access privileges of the HiRDB file system area (applicable to character special files).
The following is an example of specifying the pdfmkfs command:
pdfmkfs -n 200 -l 20 -k DB /dev/raw/raw1 |
