-
Tuning the ecache_scan_rate parameter of the Solaris
cache scrubber provides improved Ecache parity error protection on
non-mirrored SRAM UltraSPARC II-based systems (FIN I0755-1).
-
The current diagnostic procedure to
identify the faulty CPU module from CPU Ecache parity errors is flawed
(FIN I0570-3).

| PCI Card |

-
SunPCi II and SunPCi IIpro cards may not respond
after rapid/successive power cycling (FCO A0186-1).
-
Any PCI card may not seat properly and will cause
the PCI card not to be recognized by the system, rendering that
PCI card inoperable (FCO A0168-1).
-
A host system using the 375-0040-01 or -02 FC100/P
FC-AL PCI card to attach to FC-AL storage (StorEdge A5x00 and A3500)
may experience loop errors, which may affect data access to that
storage (FCO A0164-1).
-
Systems based on the PSYCHO chipset panic with a
PCI bus error (SRDB 40602).

|
|
| Power Supply |
|
|
- Improper service procedures with the E220R/E420R power supplies could
result in system downtime. In addition, under certain circumstances,
the hot swapping functionality for the redundant power supplies may
fail (FIN I0666-1)

| Removable Media Assembly (RMA) |
|
|
|
| System Board |
|
|
|
| Tape Drive |
|
|
- The peripheral D.C. power cable (530-2864-02) is too short to allow
the tape drive to be connected to D.C. power (FCO A0166-1).
