rmfs Command

Purpose

Removes a file system.

Syntax

rmfs [ -r | -i ] FileSystem

Description

The rmfs command removes a file system. If the file system is a journaled file system (JFS or JFS2), the rmfs command removes both the logical volume on which the file system resides and the associated stanza in the /etc/filesystems file. If the file system is not a JFS or JFS2 file system, the command removes only the associated stanza in the /etc/filesystems file. The FileSystem parameter specifies the file system to be removed.

You could also use the System Management Interface Tool (SMIT) smit rmfs fast path to run this command.
