You can use the
vxassist utility to create and modify volumes. Specify the basic requirements for volume creation or modification, and
vxassist performs the necessary tasks.
The advantages of using
vxassist rather than the advanced approach include:
vxassist. If necessary, you can specify additional parameters to modify or control its actions.
vxassistfinds an error or an exceptional condition, it exits after leaving the system in the same state as it was prior to the attempted
vxassist utility helps you perform the following tasks:
vxassist obtains most of the information it needs from sources other than your input.
vxassist obtains information about the existing objects and their layouts from the objects themselves.
For tasks requiring new disk space,
vxassist seeks out available disk space and allocates it in the configuration that conforms to the layout specifications and that offers the best use of free space.
vxassist command takes this form:
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:
The length of the volume can be specified in sectors, kilobytes, megabytes, gigabytes or terabytes by using a suffix character of
t. If no suffix is specified, the size is assumed to be in sectors.
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 177.
To use a different disk group, specify the
-g diskgroup option to
A large number of
vxassist keywords and attributes are available for use.
vxassist(1M) manual page.
The simplest way to create a volume is to use default attributes.
Creating a volume on any disk
More complex voluems can be created with specific attributes by controlling how
vxassist uses the available storage space.
See "Creating a volume on specific disks" on page 253.
