Before running a system recovery procedure, it is important to identify and fix the root
cause of the hardware issues.
Identifying and fixing the root cause can help recover a system, if these are the
faults that are causing the system to fail. The following are common issues that can be easily
resolved:
- The node is powered off or the power cords were unplugged.
- For any nodes that are reporting a node error 550, ensure that all the missing hardware
that is identified by these errors is powered on and connected without faults.
- If you are not able to restart the system, and if any node other than the current node is
reporting node error 550 or 578, you must remove system data from those nodes. This action
acknowledges the data loss and puts the nodes into the required candidate state.
