For high-performance h2 ECSs equipped with an InfiniBand NIC driver (InfiniBand ECSs for short), perform the following operations to check whether the driver installation is successful and whether the network communication between the ECSs is normal.
During the check, if your ECS has no command tool installed, such as ibstat, obtain the tool from the installation package for the InfiniBand NIC driver and install the tool.
ib_write_bw -x 0 --pkey_index 0
ib_write_bw -x 0 --pkey_index 0 ip_addr
In the preceding command, ip_addr is the NIC IP address of the first InfiniBand ECS.
