Solution Type Problem Resolution Sure Solution 1011235.1 : Sun Enterprise[TM] 3x00, 4x00, 5x00, and 6x00 servers: POST may fail an IO board during FEPS testing
PreviouslyPublishedAs 215431 Symptoms POST may fail an IO board during FEPS "DVMA DATA byte compare error" testing. The FEPS Chip is located on the IO board itself and the FEPS will be marked as "Failed" after POST completes. It usually shows up in POST as "DVMA DATA byte compare error" and may lead us to think that there is something wrong with the IO Board. _____________________________________________________________________________ Hardware Power ON 7,0>ERROR: TEST=OnBoard IO Chipset (FEPS),SUBTEST=FAS366 FIFO TO DMA ID=14.3 7,0>Component under test: Board 1 FEPS ASIC U3600 7,0> DVMA DATA byte compare error, address 00000000.0020301e expected 1e observed f0 xor ee 7,0>ERROR: TEST=OnBoard IO Chipset (FEPS),SUBTEST=DMA TO FAS366 FIFO ID=14.4 7,0>Component under test: Board 1 FEPS ASIC U3600 7,0> FAS366_FIFO byte compare error, address 00000000.00200002 expected 02 observed 00 xor 02 .... .... 7,0> System Board Status 7,0>----------------------------------------------------------------- 7,0> Slot Board Status Board Type Failures 7,0>----------------------------------------------------------------- 7,0> 0 | Not installed | | 7,0> 1 | Online/failure |+IO Type 4 | FEPS _________________________________________________________________________ Replacement of the IO board or the Centerplane may NOT resolve the issue. This failure usually shows up on IO Board-1, as it's a "Termination Board" for Internal Storage and Peripheral Devices. Resolution To resolve this issue, see the following: The issues surrounding such errors originate from a bad or insufficient termination of the SCSI Bus. When such errors are encountered, start to troubleshoot termination from the IO board and all the way up to SCSI Tray Assembly. Look out for FRUs named "SCSI Tray Assembly" for Sun Enterprise 4x00, 5x00 and 6x00 and "Internal Peripheral Tray SCSI Cable" part no. 530-2381 for a Sun Enterprise 3x00. The on-board SCSI adaptor on the IO board-1 itself needs to be actively terminated. Additionally, if you are still experiencing the error even after verifying the termination of the SCSI bus, the cause could be one of the internal SCSI disks on the E3000, remove them all, and insert them one at a time and run POST after each insertion. Once POST fails with the FEPS error you've found the bad disk.
