Tip - The metastat command does not sort output. Pipe the output of the metastat -p command to the sort or grep commands for a more manageable listing of your configuration.
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. For more information, see the online help.
Use the following form of the metastat command:
# metastat -p -i component-name
Specifies to show output in a condensed summary. This output is suitable for use in creating the md.tab file.
Specifies to verify that RAID-1 (mirror) volumes, RAID-5 volumes, and hot spares can be accessed.
Specifies the name of the volume to view. If no volume name is specified, a complete list of components is displayed.
