This is the error message that is printed when the lun is accesses thru
the passive paths. These are _not_ a problem.
They will not appear if all the access to the luns are thru the dm
devices (in which case you will see these only during device probing
time.
I am pushing a set of patches (currently in -mm, and hopefully will get
into 2.6.27) that will get rid of these messages.
