Previous set of patches that implemented this was posted on Mar 10: http://marc.info/?l=dm-devel&m=120519925915390&w=2 Changes have been made based on (1)test results from Dave and (2)discussions with Jens and James: - Make sure scsi_dh compiles as a modules when scsi is compiled as a module. - Set REQ_QUIET flag in the request in rdac hardware handler's prep_fn, if the path is the passive path (to reduce the extraneous error messages). Patches are created on top of 2.6.25-rc5-mm1. Testing has been done with the following storage devices: - IBM DS4800 storage device for the lsi_rdac hardware handler - HP storage device for the hp_sw hardware handler. Thanks to Dave(dwysocha@redhat.com) - EMC storage device for the EMC hardware handler. Thanks to Arthur(Benoit_Arthur@emc.com) and Ronald(asson_ronald@emc.com) In effect all hardware handlers are tested. Thanks, chandra -- ---------------------------------------------------------------------- Chandra Seetharaman | Be careful what you choose.... - sekharan@us.ibm.com | .......you may get it. ----------------------------------------------------------------------
