Background info: ------ (1) When I said we do _not_ need pp_rdac, I am referring to path priority callout code(the code I submitted on May 21st). Code under the directory path_priority/pp_rdac. (2) The path checker code I submitted on March 23rd is needed to support the LSI Engenio hardware. This code resides in libcheckers/rdac.c ------ (2) is needed and I presume you are referring to that at (A)=20 (1) is not needed and we can achieve the same with path_priority/pp_tpc/mpath_prio_tpc > Regards, > cvaroqui >=20 --=20 ---------------------------------------------------------------------- Chandra Seetharaman | Be careful what you choose.... - sekharan@us.ibm.com | .......you may get it. ----------------------------------------------------------------------
