24 The smcd device command displays SMC-D devices and their properties.
25 The smcr device command displays SMC-R devices and their properties.

28 smcd,smcr device show
29 inspect the device properties
30
31
32 all (default)
33 Show all the devices.
34
35
36 netdev NETDEV
37 SMC-R only: list only the device with the given network device
38 name.
39
40
41 ibdev IBDEV
42 SMC-R only: list only the device ports with the given RoCE de‐
43 vice name.
44
45
47 Net-Dev
48 Network device name.
49
50 IB-Dev
51 RoCE (InfiniBand) device name.
52
53 IB-P
54 InfiniBand port of the RoCE device. Note that per InfiniBand conven‐
55 tion, the port counting starts at 1. Consequently, devices where each
56 port is represented as a separate device will indicate the port as the
57 first port for all ports.
58
59 IB-State
60 State of the RoCE device port.
61
62 INACTIVE
63 The RoCE device port is inactive.
64
65 ACTIVE The RoCE device port is active.
66
67 Type
68 Type of the underlying PCI device.
69
70 RoCE_Express
71 Underlying used device is RoCE Express.
72
73 RoCE_Express2
74 Underlying used device is RoCE Express 2.
75
76 ISM Underlying used device is ISM.
77
78 Crit / InUse
79 Show whether the device is critical i.e. without failover possibil‐
80 ity(SMC-R) or whether the device is in use.(SMC-D)
81
82 Yes In case of SMC-R, there is at least one linkgroup running on the
83 device with state "SINGLE" or locally "ASYMMETRIC" which means
84 the linkgroups do not have any fail-over device in case of a
85 failure. In case of SMC-D, there is at least one linkgroup run‐
86 ning on the ISM device.
87
88 No In case of SMC-R, there is no linkgroup running on the device
89 with state "SINGLE" or locally "ASYMMETRIC" which means the
90 linkgroup(s) have a fallback device in case of a failure. In
91 case of SMC-D, there is no linkgroup running on the ISM device.
92
93 FID
94 Functional ID of the PCI device.
95
96 PCI-ID
97 ID of the PCI device.
98
99 PCHID
100 Physical channel ID of the PCI device.
101
102 #Links
103 Number of links(SMC-R)/linkgroups(SMC-D) on the device.
104
105 PNET-ID
106 PNET-ID of the device. Preceding "*" means PNET-ID is set by the user.
107 (e.g "*PNET-ID")

111 1. Show all SMC-D devices:
112 # smcd device show all
113
114 2. Show all SMC-R devices:
115 # smcr devices show all
116
117 3. Shows all SMC-R devices with RoCE (InfiniBand) device name "mlx4_0":
118 # smcr device show ibdev mlx4_0
119
120 4. Shows all SMC-R devices with network device name "eth0":
121 # smcr device show netdev eth0
