H135499 - PCI RAID SERVER TRAPS OR HANGS INTERMITTENTLY
 
 SYMPTOM:
 PC Servers with an IBM PCI RAID adapter trap or hang
 intermittently.
 
 PROBLEM ISOLATION AIDS:
 The system is a PC Server 320, 325, 330, 520, or 720 with an
 IBM PCI RAID Adapter FRU p/n06H5078 (Option p/n94G2764).
 
 FIX:
 Remove and inspect the 4MB memory SIMM FRU p/n60G2175 installed
 on the PCI RAID adapter.  If the card number on the back of the
 SIMM is HYM536120W-70 (Hyundai), replace it with FRU p/n60G2175.
 Although the FRU number has not changed, current Option, FRU,
 and Manufacturing stock do not contain the affected SIMM.
 
 The suspect 4MB Hyundai SIMMs have modules on ONE side of the
 card and are NOT compatible for use on the RAID adapter.  Other
 Hyundai SIMMs (modules on BOTH sides of the card, Hyundai card
 number HYM536100AM-70), IBM SIMMs, and Oki SIMMs are good and do
 NOT need replacing.
 
 If the suspect Hyundai SIMM (HYM536120W-70) is NOT installed,
 continue normal problem determination procedures to isolate the
 failing application or FRU.
 
 Note: Refer to RETAIN record H133523 for inspection of the PCI
       RAID adapter (ECA006).
