if Node-C is broken, have to be remove away from Cluster-A. By right before Node-C was broken, the data

Hi, about node replcement, you have to ensure that the remaining nodes on your site (where the affected cluster resides) can run the virtual machines you must need powered on and that there is a minimum quorum on your cluster (at least two nodes + witness or three nodes)

Always backup all data.

Before replacing a node, the data should be synchronized or backed up first.
Medic Lv1Posted 2024-Aug-20 10:18
  
1. Pre-Replacement Preparation
Backup Data and Configurations: Ensure that all critical data and configurations are backed up. This includes virtual machines (VMs), network settings, and storage configurations.
Health Check: Perform a health check on the cluster to ensure all nodes are functioning correctly before starting the replacement.
2. Node Removal
Data Migration: Migrate VMs and data from the node being replaced to other nodes in the cluster. This process minimizes downtime and prevents data loss.
Graceful Shutdown: Properly shut down the node to be replaced to avoid any issues during the physical replacement.
3. Physical Replacement
Hardware Compatibility: Ensure the new node is compatible in terms of hardware specifications, such as CPU, memory, and storage, with the existing cluster.
Cabling: Verify that all network, power, and storage cables are correctly connected to the new node.
4. Node Integration
Install Sangfor HCI Software: Install the appropriate version of the Sangfor HCI software on the new node.
Join the Cluster: Add the new node to the existing cluster. The system should automatically sync configurations and data.
5. Post-Replacement Procedures
Data Synchronization and Rebalancing: Allow time for data to synchronize and rebalance across the nodes. This step ensures redundancy and optimal performance.
Cluster Health Check: Perform another health check to confirm that the new node is fully integrated and that the cluster is functioning properly.
Test Failover and Load Balancing: Verify that failover and load balancing functions are working as expected with the new node.
6. Monitoring and Documentation
Continuous Monitoring: Monitor the cluster’s performance and stability after the replacement to catch any issues early.
Update Documentation: Record the node replacement details, including configurations, any changes made, and the replacement date.

The node should be in same version and in the same network segment

Hostname conflict and Resource should be more than an existing.
