The root partition is found to be read only on one of the nodes.
At this point for example:
1. The ILOM snapshot, the ilom, hostconsole logs indicates that every disk is reporting I/O errors. If you grep the console logs for "I/O error" every disk is shown to report the errors.
2. Since the root filesystem is read only it is not possible to run most commands like MegaCli to determine if a disk is failed.
