PROBLEM DESCRIPTION:
Ultra Enterprise 10000 systems may experience the symptoms listed below,
when ECC memory errors are encountered.
i) E10000 systems using SSP 3.1 with domain OS level 2.5.1, may experience
ECC memory error messages that are truncated, thus the MM numbers are
missing from the error message output. The P number is still readable
and can be used to determine the location of the failed DIMM.
ii) If the domain OS is 2.6, the P number (and the MM number if visible)
may be incorrectly reported. In this case the data from record stops
associated with the ECC error should be used to pinpoint the failed
DIMM.

IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)

---
| X | CONTROLLED PRO-ACTIVE (Per Sun Geo Plan)
---
---
| | REACTIVE (As Required)

CORRECTIVE ACTION:
In response to the above stated problem with truncated ECC memory error
messages with domain OS level 2.5.1 and the incorrect P number reporting
of domain OS level 2.6, the following recommendation has been issued for
the resolution of each problem.
1. Apply the appropriate patch for the respective Solaris release:
On the SSP:
a. Install Patch 
105684 for Solaris 2.5.1 fixes BugID: 4137422
On the E10k domains:
b. Install Patch 105181 for Solaris 2.6 fixes BugID: 4137584

COMMENTS:
The implementation status of this FIN has been upgraded to "CONTROLLED
PRO-ACTIVE". This action is warranted due to the fact the "CORRECTIVE
ACTION:" states to install a patch to avoid the reported problem. This
action fits the criteria for the implementation status of "CONTROLLED
PRO-ACTIVE".
--------------------------------------------------------------------------
Implementation Footnote:
________________________
i) In case of MANDATORY FINs, Enterprise Services will attempt to contact
all affected customers to recommend implementation of the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical sup-
port teams will recommend implementation of the FIN (to their respective
accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the need
arises.
