62 Creating application volumes
Overview of the command line interface
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.
Note: Refer to the vxassist(1M) manual page for full details on using the
vxassist command.
All operations in this chapter 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.
Note: The file, /etc/default/allocator_readme, contains a copy of the
defaults file as it is shipped and first installed.
By default, the attribute settings in the installed /etc/default/allocator
file are commented out. If required, you can uncomment the entries, and edit
their values. If you do this, you should first make a backup copy of the original
unedited file to keep for reference.
The following entry for default_rules in the /etc/default/allocator
file is commented out by default:
# default_rules=desired confineto "ProductId"
If enabled, this rule changes the default behavior of ISP so that it attempts to
confine volumes to disks with the same product ID. The rule may also prevent
