Guide
-
Specific error information must be returned
with the 400MHz US-II CPU Modules at issue to ensure correct
FRU repair (FIN I0984-1).
-
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).
-
Any Fatal Reset errors in the UE 3X00 to UE 6X00
servers should be evaluated to determined whether it is because
of Ecache Tag error. Do not assume that a Fatal Reset error implies
that the system board is defective (FIN I0587-1).
-
The current diagnostic procedure to identify the faulty
CPU module from CPU Ecache parity errors is flawed, and it could easily
lead to the wrong CPU being replaced (FIN I0570-3).
-
Cleaning kit available for cleaning silicon oil
from CPU module on the system board (FIN I0567-1).
-
Failure to handle CPU Modules correctly can result
in physical damage; proper torquing techniques are required (FIN I0403-2).
- Booting from the network can fail with Solaris 2.5.1 and Solaris 2.6
when using 464MHz or faster processors (FIN I0707-1).
- 400MHz and 464/466MHz UltraSPARC II Modules in Enterprise Server platforms
may experience system reboots or system panics (FCO A0210-1).

Disk Board |
- At system power up, the disk board does not turn on (FCO A0136-1).
- Ultra[TM] Enterprise x000 servers: Using show-disks to create devalias for Ultra disk board boot drive
(How To article 1001379.1).
- New disk board installed in a Sun Enterprise[TM] Server E4500/E5500/E6500 is not detected or recognized with probe-scsi-all. Reference Problem article 1007581.1.

Disk Drive
|
-
Improved firmware for Seagate 10K.6 disk drives will reduce the incidence of unexpected outages due to a spindle motor issue (FIN I1136-1).
-
Improved drive firmware will reduce the incidence
of HDI failures on IBM Discovery disk drives (FIN I0955-1).
- 18.2GB and 36GB IBM disk drives may be susceptible to early life failures
problem (FIN I0724-2).
- Systems with 18.2GB and 36GB IBM disk drives may experience higher than expected failure rate.
(FCO A0182-2).
- New disk board installed in a Sun Enterprise[TM] Server E4500/E5500/E6500
is not detected or recognized with probe-scsi -all (Problem article 1007581.1).
|
I/O+ Board |
-
Ultra Enterprise Exx00 I/O Boards can fail with
FEPS error during POST if installed in a slot where there are damaged
spring fingers (FIN I0800-1).
-
New service procedures are available for detached
heat sinks on EXX00 CPU and I/O boards (FIN I0683-1).
- Clarification of the hardware and software requirement to connect
the onboard SOC+ device on I/O boards used with an A3500FC StorEdge
Array (FIN I0586-1).
|
Memory |
-
Alternate 256MB DIMM part numbers are approved for use in
E3x00-E6x00 systems (FIN I1127-1).
-
When using mixed density memory modules, certain combinations
of memory banks result in fatal reset while running POST before a
system boot (FIN I0588-1).
-
ECC Memory Error Guidelines for Enterprise servers
(FIN I0377-1).
- How to read prtdiag memory interleaving on Ultra servers (Problem article 1003210.1).
-
Mitsubishi 256MB DIMMs (Sun p/n 501-5658) showing significantly
lower than expected reliability (FCO A0258-1).
|
PCI Card |
- Systems with a PGX PCI-based 8-bit Frame Buffer may display a vertical
black stripe when running the OpenWindows environment (FCO A0139-1).
- Sun Enterprise[TM] 3X00-6X00 servers: PCI i/o card address mapping on Ultra Enterprise servers (How To article 1010265.1).

slow performance on sequential write operations (FIN I0821-1).
- UDWIS SBus Host Adapter with isp-fcode 1.28 can cause "invalid command"
during probe-scsi-all or boot -hv from a StorEdge D1000 (FIN I0569-1).
- Sun FDDI SBus Adapter 5.0 SAS/DAS mounting screws may not fit the
EMI plate due to excessive plating (FIN I0469-1).
- SunATM-155 SBus board replacement may render interface unrecognizable
(FIN I0412-1).
- Large quantities of UDWIS/SBus Host Adapters installed may not come
up after reboot due to miscommunication between the SCSI host and the
target (FCO A0163-1).
