=item B<--storage>
Set the storage (number expected) ex: 1, 2,... (empty means 'check all storage').
=item B<--name>
Allows to use storage name with option --storage instead of storage oid index.
=item B<--regexp>
Allows to use regexp to filter storage (with option --name).
=item B<--regexp-isensitive>
Allows to use regexp non case-sensitive (with --regexp).
=item B<--oid-filter>
Choose OID used to filter storage (default: hrStorageDescr) (values: hrStorageDescr, hrFSRemoteMountPoint).
=item B<--oid-display>
Choose OID used to display storage (default: hrStorageDescr) (values: hrStorageDescr, hrFSRemoteMountPoint).
=item B<--display-transform-src>
Regexp src to transform display value. (security risk!!!)
=item B<--display-transform-dst>
