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
