436 Using Storage Expert
How Storage Expert works
How Storage Expert works
Storage Expert components include a set of rule scripts and a rules engine. The rules
engine runs the scripts and produces ASCII output, which is organized and archived by
Storage Expert’s report generator. This output contains information about areas of VxVM
configuration that do not meet the set criteria. By default, output is sent to the screen, but
you can send it to a file using standard output redirection.
Before using Storage Expert
Storage Expert is included in the VRTSvxvm package. Even if you do not plan to use the
VEA graphical user interface, you must also have installed the following packages to run
vxse:
■ VRTSob
■ VRTSvmpro
The VEA service must also be started on the system by running the command /opt/
VRTS/bin/vxsvc. For information about installing these components and starting the
VEA service, see the Installation Guide.
Running Storage Expert
Note: You must have root user privileges to run Storage Expert.
The executable rule files are located in the directory, /opt/VRTS/vxse/vxvm. The
examples in this chapter assume that this directory has been added to the PATH variable.
The rules are invoked using the following command-line syntax:
# rulename [options] keyword [attribute=value ...]
Each of the rules performs a different function as listed in “Rule definitions and attributes”
on page 445.
The following options may be specified:
-d defaults_file Specify an alternate defaults file.
-g diskgroup Specify the disk group to be examined.
-v Specify verbose output format.
One of the following keywords must be specified:
check List the default values used by the rule’s attributes.
info Describe what the rule does.
list List the attributes of the rule that you can set.
