Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

The vxassist command takes this form:
# vxassist [options] keyword volume [attributes...]
where keyword selects the task to perform. The first argument after a vxassist
keyword, volume, is a volume name, which is followed by a set of desired volume
attributes. For example, the keyword make allows you to create a new volume:
# vxassist [options] make volume length [attributes]
The length of the volume can be specified in sectors, kilobytes, megabytes, or
gigabytes by using a suffix character of s, k, m, or g. If no suffix is specified, the
size is assumed to be in sectors.
See the vxintro(1M) manual page.
Additional attributes can be specified as appropriate, depending on the
characteristics that you wish the volume to have. Examples are stripe unit width,
number of columns in a RAID-5 or stripe volume, number of mirrors, number of
logs, and log type.
By default, the vxassist command creates volumes in a default disk group
according to a set of rules.
See “Rules for determining the default disk group” on page 210.
To use a different disk group, specify the -g diskgroup option to vxassist.
A large number of vxassist keywords and attributes are available for use.
See the vxassist(1M) manual page.
The simplest way to create a volume is to use default attributes.
See “Creating a volume on any disk” on page 304.
More complex volumes can be created with specific attributes by controlling how
vxassist uses the available storage space.
See “Creating a volume on specific disks” on page 305.
Setting default values for vxassist
The default values that the vxassist command uses may be specified in the file
/etc/default/vxassist. The defaults listed in this file take effect if you do not
override them on the command line, or in an alternate defaults file that you specify
using the -d option. A default value specified on the command line always takes
precedence. vxassist also has a set of built-in defaults that it uses if it cannot
find a value defined elsewhere.
