Christophe, May want to patch the EMC SYMMETRIX hw entry in libmultipath/hwtable.c to use the "-ppre-spc3-83" scsi_id option. Doing so will allow scsi_id to return a UID derived from a version of a SCSI Inquiry EVPD page 83 which is not compliant with either SPC-2 or SPC-3 for an older model Symmetrix, that is, models 4, 5 and some model sixes. I should have suggested this earlier, but I assumed that it would be good enough for administrators to simply modify their /etc/scsi_id.config file to add this option as a default for all Symmetrix models. Since this assumption is likely a bad idea :((, I think we should include the new option in the multipath default configuration. Udev will need similar changes since we likely cannot rely on the scsi_id.config file being setup properly by a site administrator. Here is the patch. diff --git a/libmultipath/hwtable.c b/libmultipath/hwtable.c --- a/libmultipath/hwtable.c +++ b/libmultipath/hwtable.c @@ -17,7 +17,7 @@ setup_default_hwtable (vector hw) r += store_hwe(hw, "COMPAQ", "MSA1000 VOLUME", GROUP_BY_SERIAL, DEFAULT_GETUID); r += store_hwe(hw, "DDN", "SAN DataDirector", MULTIBUS, DEFAULT_GETUID); r += store_hwe(hw, "DEC", "HSG80", GROUP_BY_SERIAL, DEFAULT_GETUID); - r += store_hwe(hw, "EMC", "SYMMETRIX", MULTIBUS, DEFAULT_GETUID); + r += store_hwe(hw, "EMC", "SYMMETRIX", MULTIBUS, "/sbin/scsi_id -g -u -ppre-spc3-83 -s /block/%n"); r += store_hwe(hw, "FSC", "CentricStor", GROUP_BY_SERIAL, DEFAULT_GETUID); r += store_hwe(hw, "HITACHI", "DF400", MULTIBUS, DEFAULT_GETUID); r += store_hwe(hw, "HITACHI", "DF500", MULTIBUS, DEFAULT_GETUID);
