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. > > Thanks, > Gustavo Riveros > > -- > dm-devel mailing list > dm-devel@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/dm-devel -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
