Hello Tanya,  We appreciate your ingenuity. We strongly discourage any plan or attempt to format the boot disk and add it to another node.  The best course of action would be to allow the system’s hardware and software preservation to run as designed.  Best practices for this situation: If the node is in a state that is less than optimal, we would recommend initiating a smartfail on the affected node. This will re-protect the data and allow the cluster to resume its intended operation. We would first want to confirm that the cluster has more than four nodes of the same type and that sufficient capacity is available to successfully smartfail out the node.  The affected node can be assessed at a later date and brought back up to par once is out of theater or when replacement parts can be made available or spares obtained.  Any attempts to circumvent the system’s protection mechanisms will end poorly. The connection adapter to the boot drive is a specialized connection. As you’d mentioned the boot drive once out of the original node is unusable for any other means.  Pat
How do you reformat a boot drive back to factory defaults when it has been used in one node, to be used as a replacement in another node?
