Repair Actions
When you have determined the parts of the failing link, check whether the cause of the
problem is obvious; for example, a loose cable connection, or a disk drive with its
Check light on. If the cause is obvious, correct it. If the cause is not obvious, exchange
the parts of the link, one at a time, until the problem is solved.
