Fix hardware errors
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 which can be easily resolved:
- The node has been 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 have not been 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.
