List disk path (UCD-SNMP-MIB).
Need to enable "includeAllDisks 10%" on snmpd.conf.
=over 8
=item B<--diskpath>
Set the disk path (number expected) ex: 1, 2,... (empty means 'check all disks path').
=item B<--name>
Allows to use disk path name with option --diskpath instead of disk path oid index.
=item B<--regexp>
Allows to use regexp to filter diskpath (with option --name).
=item B<--regexp-isensitive>
Allows to use regexp non case-sensitive (with --regexp).
=item B<--display-transform-src>
Regexp src to transform display value. (security risk!!!)
=item B<--display-transform-dst>
Regexp dst to transform display value. (security risk!!!)
=item B<--skip-total-size-zero>
Filter partitions with total size equals 0.
