Diagnostics and Maintenance

6.4Troubleshooting Procedures

6.4.1Outline of troubleshooting procedures

This section explains the troubleshooting procedures for disk drive errors.

Depending on the maintenance level, analyze the error to detect a possibly faulty part (disk drive, or disk drive 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 disk enclosure or burning of the PCA), troubleshooting is straightforward.

6.4.2Troubleshooting with disk drive replacement in the field

At this level of maintenance, we recommend replacing the disk drive as a unit. If replacing the disk drive rectifies the fault, return the removed disk drive to the factory, for test and repair. If the newly installed disk drive 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 (disk drive or system).
