SMCD-DEVICE(8)

NAME
smcd-device - Print information about SMC-D devices

smcr-device - Print information about SMC-R devices

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)
    List all devices.

netdev NETDEV
    SMC-R only: limit the command output to the device with the specified network device name.

ibdev IBDEV
    SMC-R only: limit the command output to the device port with the specified RoCE device name.

OUTPUT

  Net-Dev
Network device name.

  IB-Dev
RoCE (InfiniBand) device name.

  IB-P
InfiniBand port of the RoCE device. According to the InfiniBand conventions, the port count 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 For SMC-R, there is at least one link group running on the device with state "SINGLE" or locally "ASYMMETRIC" which means one or more link groups without a failover device in case of a link failure. In case of SMC-D, there is at least one link group running on the ISM device.

No  For SMC-R, there is no link group running on the device with state "SINGLE" or locally "ASYMMETRIC" which means the link group(s) have a fallback device in case of a failure. In case of SMC-D, there is no link group running on the ISM device.

  FID
Function ID of the PCI device.

  PCI-ID
ID of the PCI device.

  PCHID
Physical channel ID of the PCI device.

  #Links
Number of links (SMC-R)/link groups (SMC-D) on the device.

  PNET-ID
PNET ID of the device. Leading asterisk "*" means PNET ID is set by the user. (e.g "*PNET-ID")

EXAMPLES

1. Show all SMC-D devices:
# smcd device show all

2. Show all SMC-R devices:
# smcr devices show all

3. Show all SMC-R devices with RoCE (InfiniBand) device name "mlx4_0":
# smcr device show ibdev mlx4_0

4. Show all SMC-R devices with network device name "eth0":
# smcr device show netdev eth0
