Description ranjith ruban 2011-07-20 22:13:58 UTC 
Description of problem:

There is no /var/lib/multipath/bindings file in rhel6 . It have been changed to /etc/multipath/bindings

The below in the doc at page 139

----------
When the user_friendly_names feature (of device-mapper-multipath) is used, the WWID is mapped to a name of the form /dev/mapper/mpathn. By default, this mapping is maintained in the file /var/lib/multipath/bindings. These mpathn names are persistent as long as that file is maintained.
Warning
The multipath bindings file (by default, /var/lib/multipath/bindings) must be available at boot time. If /var is a separate file system from /, then you must change the default location of the file. For more information, refer to http://kbase.redhat.com/faq/docs/DOC-17650.

should be changed to below

The text has been changed however the default path appears contradictory in the Warning admonition, should this be changed also?
