Resolving The Problem
When troubleshooting RAID subsystem errors, including tape, hard drive, and CD-ROM errors on PC Server 500 (8641) and PC Server 720 (8642) RAID systems, do the following:
-
Inspect the four digit date code (ww/yy or wwyy) on the RAID controller to Backplane cable FRU 82G3613.
- If the date code is earlier than (13/95 or 1395), replace the cable with FRU 82g3613.
- Although the FRU number has not changed, the affected cables have been cleared from stock.
- The first two numbers (ww) are the week and the second two numbers (yy) are the year of manufacture.
- Cables manufactured before (13/95 or 1395) have end caps which may not be securely latched.
- All current inventory should be dated (13/95 or 1395) and later.
