Maintenance and Diagnosis
7.3 Troubleshooting Procedure
7.3.1 Troubleshooting procedure
This section describes the troubleshooting procedures for a disk drive failure at
field maintenance level described in Subsection 7.1.3.
In this section, troubleshooting is made to isolate the reported failure to the disk drive
or a host system. Usually, troubleshooting is necessary only when a cause of failure is
uncertain or unknown. When a cause of failure is clear (for example, abnormal sound
in the DE or burnt parts on the PCA), a level of troubleshooting is low.
7.3.2 Troubleshooting disk drive replaced in field
It is recommended that the whole drive be replaced in maintenance of this level. If
replacing the drive corrects the fault, return the old drive to the factory for testing
and repair. If the new drive shows the same fault as the one that was removed, the
failure is elsewhere in the system.
System level troubleshooting, shown in Table 7.3, is performed at the user site to
isolate the reported failure to the disk drive or system.
