Sun Fire[tm] V880 Server: Repair Procedures

• Diagram showing cable connector locations is on page 221

• Table showing cable routing information is on page 222. The cabling instructions for the Loop B PCI FC-AL data cable are incorrect in the Sun Fire V880 Service Manual, due to a late change to the labeling scheme on the cable's connectors. The correct cabling information is provided below:
  
  

  Cable Name	Part Number	Cable End	Connect To
  Loop B PCI FC-AL data cable	530-3056	D	Base backplane at D
  		C	Base backplane at C
  		P3	PCI card at J3
  		P4	PCI card at J4

• prtdiag reports fan failures as ENABLED with a speed of 0 (BugID 4431194). Please check the current revision of the Sun Fire V880 Server Product Notes for more information.

• Guidelines for understanding and diagnosing UltraSPARC III Level 2 (L2) SRAM Cache Memory Errors (FIN I0887-1).
• UltraSPARC III and III+ based platforms could be susceptible to UCC errors that may cause system panics (FIN I0856-1).

• The 3.3V DC-DC Converter on Sun Fire V880 CPU/Mem Boards may cause the system to shutdown and start reboot process around the failed CPU/Mem Board (FCO A0188-1).

• 816-4517 - This document describes the procedure for replacing the DC-to-DC converter on a 750 MHz CPU/Memory board (part number 501-5818-05) for the Sun Fire V880 server. You must replace the DC-to-DC converter on every -05 CPU/Memory board that has not had work order WO_23160 performed on it. This must be done for every -05 CPU/Memory board in a system. A -05 CPU/Memory board that already has the replacement DC-to-DC converter on it is identified by the work order label WO_23160 affixed to the front label of the board, as shown in the following illustration.
  Note: You do not have to replace the DC-to-DC converter on the -07 750 MHz CPU/Memory board, part number 501-5818-07.

• NOTE: When updating the disk backplane firmware using patch 111474, the superuser prompt will return after issuing the luxadm command in step 2 of the patch instructions. You must wait at least 15 minutes after the superuser prompt returns before continuing or performing any other operations. This minimum wait time is required for the flash update process to propagate the firmware code to all SSC100 processors in the system.

• The procedure How to Install the Expansion FC-AL Backplane as documented in the Sun Fire V880 Server Service Manual is incomplete. Please check the current revision of the Sun Fire V880 Server Product Notes for the corrected procedure.

• The procedure How to Install the FC-AL Disk Cage as documented in the Sun Fire V880 Server Service Manual is incomplete. The following task should be included as Step 9c:

9c. If a Sun StorEdge PCI Dual Fibre Channel Host Adapter card is installed to control Loop B of the FC-AL disk backplane, connect the card s FC-AL data cable to the base backplane at connectors C(J01100) and D(J01101).

• Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue (FIN I1136-1).
• Power management issue causes loss of access to internal fiber channel disks on the Sun Blade 1000/2000, Sun Fire V880, V480, and 280R (FIN I0888-1).
• Invalid Device structure found after disk removal when under Volume Manager 3.2 Control (FIN I0854-3).
• Seagate ST336605FC 36GB and ST373405FC 73G drives could be susceptible to label corruption (FIN I0816-1).
• Removing and Replacing the Sun Fire 280R (Littleneck), 480R (Cherrystone), or 880R (Daktari) hot-pluggable internal disk drives (Problem article 1007367.1).
• Correcting device paths when replacing fiber boot disks after a ufsrestore (How To article 1003103.1).
• All FC-AL disk drives installed in a Sun Fire V880 system must meet the minimum firmware revision levels for Sun Fire V880 systems. Incorrect firmware can cause a variety of system problems that are often difficult to diagnose. To determine a disk drive's firmware revision level, use the inquiry feature of the Solaris format(1M) utility. The following table shows the minimum firmware revision levels for Sun Fire V880 disk drives as of 8/31/01. Please check the current revision of the Sun Fire V880 Server Product Notes for current information.
  
  

  Sun Part No.	Capacity	Manufacturer	Minimum Firmware Revision Level
  540-4525	Seagate Seagate	ST336605FC ST336704FC	0438 0726
  540-4905	Seagate	ST373405FC	0438

• The procedure How to Install a Disk Drive as documented in the Sun Fire V880 Server Service Manual and the Sun Fire V880 Server Owner s Guide is incomplete. The following task should be included in the procedure after Step 10:
