D
OCP Error Codes
This appendix lists the OCP (operator control panel) error codes provided in
the host error log and the code displayed by the OCP. Use Table D–1 to convert
the pattern of lights to OCP codes and to obtain a list of recommended FRUs to
replace.
OCP error codes not listed
may be
an RA7x disk drive error code. RA7x disk
drive codes are listed in
RA7x Disk Drive Service Manual
with recommendations
for FRUs to replace for each code. For
some
OCP error codes you are specifically
directed to obtain the drive error code and then refer to the disk drive service
manual appendix for complete information.

Obtain the drive error code from the host error log, the internal drive error log, or the HSC console.
Then locate the drive error code in
RA7x Disk Drive Service Manual
for complete information.
