30
31
32 all (default)
33 List all devices.

35
36 netdev NETDEV
37 SMC-R only: limit the command output to the device with the
38 specified network device name.
39
40
41 ibdev IBDEV
42 SMC-R only: limit the command output to the device port with the
43 specified RoCE device 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. According to the InfiniBand conven‐
55 tions, the port count 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 For SMC-R, there is at least one link group running on the de‐
83 vice with state "SINGLE" or locally "ASYMMETRIC" which means one
84 or more link groups without a failover device in case of a link
85 failure. In case of SMC-D, there is at least one link group
86 running on the ISM device.
87
88 No For SMC-R, there is no link group running on the device with
89 state "SINGLE" or locally "ASYMMETRIC" which means the link
90 group(s) have a fallback device in case of a failure. In case
91 of SMC-D, there is no link group running on the ISM device.
92
93 FID
94 Function 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)/link groups (SMC-D) on the device.
104
105 PNET-ID
106 PNET ID of the device. Leading asterisk "*" means PNET ID is set by the
107 user. (e.g "*PNET-ID")
108

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. Show all SMC-R devices with RoCE (InfiniBand) device name "mlx4_0":
118 # smcr device show ibdev mlx4_0
119
120 4. Show all SMC-R devices with network device name "eth0":
121 # smcr device show netdev eth0
