8.4.2 Bottom-Up Commands
The bottom-up approach to storage management allows you to control the
placement and definition of subdisks, plexes, and volumes. Bottom-up
commands allow a great deal of precision control over how LSM creates
and connects objects together. You should have a detailed knowledge of the
LSM architecture before using these commands.
Bottom-up commands include volmake to create LSM objects, and
volume, volplex, and volsd to manipulate volume, plex, and subdisk
objects. The syntax for these commands is as follows:
volmake
[-U usetype][-ouseopt][-d file][type name[ attribute]]...
volume [-U usetype][-o useopt][-Vq] keyword argument...
volplex [-U usetype][-o useopt][-V][-v volume] keyword argument...
volsd [-U utype][-o uopt][-V][-v volume][-p plex] keyword argument...
8.4.3 Information Command
The volprint command, which has built-in parsing and formatting
features, displays most of the LSM configuration and status information.
The volprint command has the following syntax:
volprint
[-AvpsdGhnlafmtqQ][-g diskgroup][-epattern][-D database]
[
-F[ type:] format-spec][name...]
8.5 Planning an LSM Configuration
Before setting up LSM volumes, plexes, and subdisks, you should consider
the needs of your site, the hardware available to you, and the rationale for
creating volumes and disk groups.
Table 8–4 presents some configuration options and describes the planning
considerations that apply to LSM configurations.
