52 should be b&c. controller failure has nothing to do with this type of issue. degraded state tells us its a raid issue, and if the os is missing then the bootable device isnt found. the only other consideration could be data loss but thats somewhat broad whereas b&c show understanding of the specific issues the question is asking about.
