12.1 File System Management Commands

For each file system, there are two different types of management commands, namely, the general purpose management commands and the system specific management commands. The general purpose management commands that provided by Solaris OS are used for basic functions and the system specific commands are called by specifying options or file system types.

The GFS Shared File System features an exclusive management commands that act as the general purpose management command and the system specific management command for the GFS Shared File System's original functions.

Specify "sfcfs" for -F option as a file system type when using the general purpose management command to a GFS Shared File System. If you omit the -F option, a search is made of those entries matched with "special" or "mount_point" in /etc/vfstab after which the registered file system types are automatically selected.
