Configuring Remote O&M for an MRS Cluster

If you encounter any issues while using a cluster and require assistance from Huawei Cloud support personnel, you can first contact them. Then, you can authorize them to access your machine through the O&M authorization function to locate the fault. Alternatively, you can provide Huawei Cloud support personnel with logs from a specific time period using the log sharing function to help them locate the fault.

Enabling Remote O&M Authorization for an MRS Cluster

Log in to the MRS management console.
In the navigation pane of the MRS management console, choose Active Clusters, select a running cluster, and click its name to switch to the cluster details page.
In the upper right corner of the page, click O&M, choose Authorize for Cluster Nodes, and select the deadline for the HUAWEI CLOUD support engineers to access the local host. Before the deadline, the support personnel have the temporary permission to access the local host.
Select the check box to confirm authorization and click OK.
After the fault is rectified, click O&M in the upper right corner of the page and choose Deauthorize for Cluster Nodes to retrieve the access permission granted to the HUAWEI CLOUD support engineers.

Configuring Remote O&M Log Sharing for an MRS Cluster
