| SMCD-DEVICE(8) | Linux Programmer's Manual | 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.
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
