Volume Manager Commands
vxmake - creating VM objects
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 objectto 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 -U usage_type vol volume_name len= length
plex= plex_name,...
where:
• the first operand (keyword) determines the kind of object to be
created
• the second operand is the name given to that object
• additional operands specify attributes for the object
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_file option
specifies a filename. The following is a sample description file:
