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”
