6.4 Troubleshooting
6.4.1
Outline of troubleshooting procedures
This section explains the troubleshooting procedures for HDD errors.
Depending on the maintenance level, analyze the error to detect a possibly faulty part (HDD, or
HDD part).
Full-scale troubleshooting is usually required if the error cause is not known. If the error cause is
clear (e.g., abnormal noise in DE or burning of the PCBA), troubleshooting is straightforward.
6.4.2
Troubleshooting with HDD replacement in the field
At this level of maintenance, we recommend replacing the HDD as a unit. If replacing the HDD
rectifies the fault, return the removed HDD to Fujitsu, for test and repair. If the newly installed
HDD does not rectify the fault another part of the system is faulty.
Table 6.2 summarizes system-level field troubleshooting. Troubleshooting must be done in the
field, to find faulty part (HDD or system).
