The potential causes for such an alert are numerous, ranging from the benign to the catastrophic. It could be a transient I/O error caused by a hiccup in the storage area network (SAN), or it could be the early warning sign of a physical disk sector corruption. In some cases, it may relate to a mismatch in ASM attributes following a patch or a configuration drift. Regardless of the root cause, the Health Checker acts as the canary in the coal mine.
