Replacing Physical Machines (Automated)
This topic describes how to replace a failed physical machine (PM), or node, in a dual-node ztC Edge system with the automated node replacement process. It supplements the information in ztC Edge 100i/110i Systems: Replacing a Node (R013Z).
You replace a node in a dual-node system while the system is running.
Prerequisite: To request a replacement ztC Edge node, log on to the Stratus Customer Service Portal, expand Customer Support, and click Add Issue. When creating the issue, please have the following information ready:
- Asset ID—Locate the Asset ID for your system in the masthead of the ztC Console window.
- Diagnostic file—Generate and download a diagnostic file on the Support Logs page of the ztC Console, as described in Creating a Diagnostic File. Attach the diagnostic file to the issue that you add in the Service Portal.
A customer service representative will contact you to diagnose the issue and provide a replacement node, if necessary.
To replace a node in a ztC Edge system
- Locate the node to replace. The faulted node is either powered off (automatically) or powered on with the SYS LED off or solid green (not healthy). If the node is already powered off, skip to step 3.
- If the faulted node is still powered on, open the ztC Console to resolve any issues blocking shutdown. For example, a failed network connection on the healthy node can cause a dependency on the faulted node. Resolve any issues and shut down the faulted node.
- Disconnect the power cable from the faulted node, then disconnect the network cables and remove the node from system.
- Add the replacement node to the system. Reconnect the network cables, then reconnect power to automatically power on the node. The node replacement is complete. The system begins to synchronize with no user input required.
- After 20 minutes, the SYS LED cycles from off to solid green to show that the software on the replacement node is starting. After another 15 minutes, the SYS LED starts flashing to show that the system is healthy.
- Log on to the ztC Console to confirm the system health. The virtual machines may continue to synchronize for hours. After synchronization completes successfully, the Dashboard should display green check marks with no outstanding issues.
