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.
- Check the node status of every node that is a member of the
system. Resolve all errors.
- 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.
