Creating Plexes
The vxmake command creates Volume Manager objects, such as plexes.
When you create a plex, you identify subdisks and associate them to the
plex that you want to create.
To create a plex from existing subdisks, use the following command:
# vxmake plex plex_name sd= subdisk_name ,...
For example, to create a concatenated plex named vol01-02 using two
existing subdisks named disk02-01 and disk02-02, use the following
command:
# vxmake plex vol01-02 sd=disk02-01,disk02-02
Creating a Striped Plex
To create a striped plex, you must specify additional attributes. For
example, to create a striped plex named pl-01 with a stripe width of 32
sectors and 2 columns, use the following command:
# vxmake plex pl-01 layout=stripe stwidth=32 ncolumn=2\
sd=disk01-01,disk02-01
To use a plex to build a volume, you must associate the plex with the
volume. For more information, see the following section, “Associating
Plexes”
