Table 8–3: LSM Administration Interfaces
Interface Type Description
Visual
Administrator
(dxlsm)
Graphical Uses windows, icons, and menus to manage LSM
volumes. The dxlsm graphical interface requires a
workstation. The interface interprets the
mouse-based icon operations into LSM commands.
The Visual Administrator (dxlsm) interface
requires the LSM software license.
Support
Operations
(voldiskadm)
Menu Provides a menu of disk operations. Each entry in
the main menu leads you through a particular
operation by providing you with information and
asking you questions. Default answers are provided
for many questions. This character-cell interface
does not require a workstation.
Command line Command Provides two approaches to LSM administration.
With the top-down approach, you use the LSM
volassist command to automatically build the
underlying LSM objects. With the bottom-up
approach, you use individual commands to build
individual objects to customize the construction of
an LSM volume.
8.4 LSM System Administration Commands
The following sections summarize some useful commands from the
command line interface. Examples of how to use some of these commands
are included in Section 8.6.
See also the appropriate reference pages and the manual Logical Storage
Manager for detailed information and examples.
8.4.1 Top-Down Command
The top-down approach to managing storage means placing disks in one
large pool of free storage space. You then use the volassist utility to
specify to LSM what you need, and LSM allocates the space from this free
pool. You can use volassist to create, mirror, grow, or shrink a volume.
With volassist, you can use the defaults that the utility provides, or you
can specify volume attributes on the command line.
The volassist command has the following syntax:
volassist
[-b][-g diskgroup ][-U usetype ][-d file ] keyword
argument
...
