Error Analysis
7-4 C141-E235
7.2.2 Sense data (3-0C-03), (4-40-xx), and (4-C4-xx)
Sense data (3-0C-03), (4-40-xx), and (4-C4-xx) indicate one of the following:
• A target sector could not be detected using the sector counter.
• A seek process overran the specified time.
• A write to a disk terminated abnormally.
• An error occurred in power-on self-diagnosis.
• A drive error occurred.
The symptoms above are generally caused by an error in the PCA or the DE.
7.2.3 Sense data (1-1x-xx), (3-1x-xx) and (E-1D-00): Disk read error
If sense data (1-1x-xx), (3-1x-xx) or (E-1D-00) occurs frequently in a specific block of a disk, there
is disk damage that was not recorded in the media defect list. In this case, assign an alternate block
to the error-detected block using a REASSIGN BLOCKS command. For an explanation of the
REASSIGN BLOCKS command, refer to Subsection 4.3.2 “REASSIGN BLOCKS (07)” of the Fibre
Channel Interface Specifications.
If this error occurs in different blocks, the PCA or the DE is faulty.
7.2.4 Sense data (4-44-xx), (5-2x-xx), (B-44-xx), (B-47-xx), (B-49-00) and (B-4E-00): fibre channel
interface error
Sense data (4-44-xx), (5-2x-xx), (B-47-xx), (B-49-00) and (B-4E-00) indicates one of the following
symptoms:
• An invalid or unsupported command was issued, or invalid or unsupported parameters were
specified.
• A SCSI error occurred.
• A hardware error occurred inside the HDD.
• A CRC error occurred in the fibre channel loop.
If this error occurs, the PCA or the fibre channel interface is faulty.
