Overview of the command line interface

You can use the vxassist command to create and manage ISP volumes provided

that you have set up a storage pool in the disk group. ISP optimally assigns storage

resources as defined and constrained by any parameter values, rules, capabilities

and templates that you specify as arguments to the command. Capabilities provide

the highest, most abstract way of specifying volumes. Rules provide the lowest,

most direct means of specification. This gives you great freedom to create volumes

that meet your requirements.

The vxassist command takes the following general form:

# vxassist [options] keyword volume [additional_arguments] \

[storage_specification] [attribute=value ...]

The keyword denotes the action that vxassist is to perform on the named volume.

The storage specification defines the storage that can or cannot be used with an

operation. This consists of a comma-separated list of disk media names and other

storage attributes, such as Controller:controller_name to indicate all disks on

a controller. Excluded storage is indicated by a ! prefix. Finally, attributes and

their values can be used to specify further constraints on the operation.

Each invocation of vxassist is applied to only a single storage pool that has been

configured within a disk group. The default disk group is that aliased by the setting

of defaultdg. You can specify an alternate disk group by using the -g diskgroup

option.

Refer to the vxassist(1M) manual page for full details on using the vxassist

command.

The operations for ISP that use the vxassist command have an equivalent

vxvoladm command, which is obtained by substituting vxvoladm for vxassist.

Any other arguments to the command remain the same.

Setting default values for ISP volumes

You can define default values for ISP volumes in the file /etc/default/allocator

or in an alternate file that you specify as an argument to the -d option. The defaults

listed in this file are used unless they are overridden by a value specified on the

command line. If a value is not defined in a defaults file or on the command line,

vxassist uses a built-in default value.
