When the cluster virtualization platform is VMware ESXi with RDMA enabled, you need to configure the RDMA access network after the cluster is deployed. Run this command to configure the VMware access network of the SCVM node. The command connects to the ESXi host where the SCVM resides to retrieve network information and uses it to complete the configuration.
Procedure
Run the following command on any node in the cluster:
zbs-deploy-manage deploy-rdma
Output example
If Finish deploy RDMA is displayed, the configuration is successful.
Configure flow control for the storage network or the access network.
Procedure
Run the following command on the node where you want to configure flow control:
zbs-deploy-manage config-rdma-fc [--storage_qos_mode <storage_qos_mode>] [--access_qos_mode <access_qos_mode>]
Parameter description
| Parameter | Description |
|---|---|
