Hi Christopher, sorry - the software development is not my daily business.... The file hwtable.c should be changed from: ... r += store_hwe(hw, "HITACHI", "DF400", MULTIBUS, DEFAULT_GETUID); r += store_hwe(hw, "HITACHI", "DF500", MULTIBUS, DEFAULT_GETUID); r += store_hwe(hw, "HITACHI", "DF600", MULTIBUS, DEFAULT_GETUID); ... to: ... r += store_hwe(hw, "HITACHI", "DF", GROUP_BY_PRIO, DEFAULT_GETUID, "/sbin/pp_hds_modular %d", "0", "0", "readsector0", FAILBACK_IMMEDIATE); r += store_hwe(hw, "HITACHI", "OPEN-", MULTIBUS, DEFAULT_GETUID); ... First entry is for Hitachi Modular Storage Active/Passive. The Product inquiry always begins with "DF". Second entry is for Hitachi Enterprise Storage Active/Active. The Product inquiry always begins with "OPEN-". Regards, Matthias -- dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
