Hi ALL. I'm having some problems and could not find solution with technical support. My server is two multipathd running processes. I noticed that when there is a failure to communicate with the SAN device looks like this: volclu2 (36000144000000010700aa26e0e57b5b9) dm-36 EMC Invista size = 1.0G features = '0' hwhandler = '0' wp = rw `- + - Policy = 'queue-length 0' prio = 0 status = enabled | - 0: 0: 0: 20 65:64 sdu failed running faulty | - 0: 0: 1: 20 sdaq 66: 160 failed running faulty | - 1: 0: 0: 20 sddf 70: 208 failed running faulty `- 1: 0: 1: 20 sdeb 128: 48 failed running faulty And then the communication is re-established looks like this: volclu2 (36000144000000010700aa26e0e57b5b9) dm-36 EMC Invista size = 1.0G features = '0' hwhandler = '0' wp = rw `- + - Policy = 'queue-length 0' prio = 1 Status = enabled | - 0: 0: 0: 20 65:64 sdu failed running ready | - 0: 0: 1: 20 sdaq 66: 160 failed running ready | - 1: 0: 0: 20 sddf 70: 208 failed running ready `- 1: 0: 1: 20 sdeb 128: 48 failed running ready The failback is not being automatic. The status of the device is "enable" rather than "active". The status only changes to "active" when I run "multipath -v3". - What can cause the creation of two daemon multipathd? Regards, Juliano.
