vxmake - creating VM objects

You can use the vxmake command to add a new volume, plex, or subdisk to the set of objects managed by Volume Manager. vxmake adds a new record for that object to the Volume Manager configuration database. You can create records from parameters specified on the command line or by using a description file.

You can specify operands on the command line as follows:

vxmake -Uusage_type vol volume_name len=length plex=plex_name,...

where:

If no operands are specified on the command line, then a description file is used to specify the records to create.

A description file is a file that contains plain text that describes the objects to be created with vxmake. A description file can contain several commands, and can be edited to perform a list of tasks. The description file is read from standard input, unless the -d description_fileoption specifies a filename. The following is a sample description file:

#rectyp #name       #options

This description file specifies a volume with two plexes. The first plex has five subdisks on physical disks. The second plex is preferred and has one subdisk on a volatile memory disk.
