Verifying the attachment of the ESS volumes
To verify the attachment of the ESS volumes, use the hwmgr command. See
Figure 25 for an example of the commands you can use to verify the attachment of
the ESS volumes.
Figure 26 shows an example of the Korn shell script called essvol. Figure 26 shows
a summary that includes information for all the ESS volumes that are attached.
See Figure 27 on page 35 for an example of what displays when you execute the
essvol korn shell script.

attachment
echo Extracting ESS volume information...
