Parameter setting part of dm multipath handler has been removed when we moved to scsi device handler. This set of patches adds an new interface to scsi_dh and uses it. This patch set applies on 2.6.31-rc1 and the following 2 patches: (1) http://patchwork.kernel.org/patch/32646/raw/ (2) http://patchwork.kernel.org/patch/32647/raw/ This interface part of the patch has been tested. Eddie, If you can test it on an EMC storage and respond with your findings it will be of great help. Thanks, chandra
