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.
