Synopsis

smcd [ OPTIONS ] device { COMMAND | help }

smcd device [ show ] [ all ]

smcr [ OPTIONS ] device { COMMAND | help }

smcr device [ show ] [ all ] [ netdev NETDEV ] [ ibdev IBDEV ]

Description

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

smcd,smcr device show

inspect the device properties

all (default): Show all the devices.
netdev NETDEV: SMC-R only: list only the device with the given network device name.
ibdev IBDEV: SMC-R only: list only the device ports with the given RoCE device name.

Output

InfiniBand port of the RoCE device. Note that per InfiniBand convention, the port counting starts at 1. Consequently, devices where each port is represented as a separate device will indicate the port as the first port for all ports.

IB-State

State of the RoCE device port.

INACTIVE: The RoCE device port is inactive.
ACTIVE: The RoCE device port is active.

Type

Type of the underlying PCI device.

RoCE_Express: Underlying used device is RoCE Express.
RoCE_Express2: Underlying used device is RoCE Express 2.
ISM: Underlying used device is ISM.

Crit / InUse

Show whether the device is critical i.e. without failover possibility(SMC-R) or whether the device is in use.(SMC-D)

Yes: In case of SMC-R, there is at least one linkgroup running on the device with state "SINGLE" or locally "ASYMMETRIC" which means the linkgroups do not have any fail-over device in case of a failure. In case of SMC-D, there is at least one linkgroup running on the ISM device.
No: In case of SMC-R, there is no linkgroup running on the device with state "SINGLE" or locally "ASYMMETRIC" which means the linkgroup(s) have a fallback device in case of a failure. In case of SMC-D, there is no linkgroup running on the ISM device.
