Creating application
volumes
Volumes created by Veritas Intelligent Storage Provisioning (ISP) are similar to
traditional non-ISP volumes that you create using the
vxassist utility, but
have the advantage that their intent is preserved and cannot accidentally be
degraded. Volumes that are created by ISP can be managed by using commands
such as
vxassist or vxvoladm, or by using the VEA client graphical user
interface. For information on using VEA to create volumes, refer to the VEA
online help. This chapter describes how to use the
vxassist command to create
ISP volumes.
Note: To create application volumes successfully, the appropriate licenses must
be present on your system. For example, you need a full Veritas Volume
Manager license and a Veritas FlashSnap
TM
or FastResync license to use the
instant snapshot feature. Vendors of disk arrays may also provide capabilities
that require special licenses for certain features of their hardware.
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 general form:
# vxassist [ options ] keyword volume [ additional_arguments ] \
[
storage_specification ] [ attribute = value ...]
