Example—Creating A Volume With Changed Defaults for the metassist Command

Before creating a volume, edit the /etc/default/metassist.xml file to specify the default settings that you want to apply to all volumes you will create with the metassist command. In this example, the metassist command will only create volumes on controller c1 and, when creating stripes, will only create stripes with exactly 4 components and an interlace of 512KB. These constraints will apply to all uses of the metassist command until the /etc/default/metassist.xml file is changed again.

#  cat /etc/default/metassist.xml 
<!DOCTYPE volume-defaults SYSTEM \
"/usr/share/lib/xml/dtd/volume-defaults.dtd">

<volume-defaults>
<available name="c1" />
<stripe mincomp="4" maxcomp="4" interlace="512KB" ></stripe>
</volume-defaults>

# metassist create -s myset -S 10Gb
 

This example shows how to use the metassist command to create a 10GB stripe, using exactly four slices and an interlace value of 512KB, as specified in the /etc/default/metassist.xml file.
