PROBLEM DESCRIPTION:
A Sun Fire 12K or 15K domain may Domain Stop (Dstop) during heavy I/O
load. All execution and activity on the domain is interrupted. The
Dstop could result in data loss.
This issue can occur in the following releases:
Sun Fire 12K/15K SMS 1.1
Sun Fire 12K/15K SMS 1.2 without patch 
112488
Below are error messages that might be seen in the /var/adm/messages

Err0[18]: D 1E Timeout on command reissue transaction to Slot0
FAIL Slot SB0: Dstop/Rstop detected by AXQ.
The FRU named in this failure (SB0) cannot be identified from the
available information, so this error is not diagnosable. The FAIL
action is just a guess to satisfy the POST design requirement that
something must be deconfigured after a Dstop to guarantee that the
process terminates. The failed component is not more suspect than any
other hardware in the domain.
This issue occurs because the current interconnect hardware is not able
to handle Local Physical Addresses (LPA) as implemented with the SMS
software. The hardware only supports LPA in very restricted
configurations and may be subject to protocol errors under heavy load.
This issue is fixed by Patch 112488 for SMS 1.2.
IMPLEMENTATION:
---
| | MANDATORY (Fully Proactive)
---
---
| X | CONTROLLED PROACTIVE (per Sun Geo Plan)
---
---
| | REACTIVE (As Required)
---
CORRECTIVE ACTION:
The following recommendation is provided as a guideline for authorized
Enterprise Services Field Representatives who may encounter the above
mentioned problem.
1. For Sun Fire 12/15K systems with SMS 1.2, install Patch 112488 or
later.
OR
2. For Sun Fire 12/15K systems with SMS 1.1 it is recommended to upgrade
to SMS 1.2 and then install the above mentioned patch.
Note: When upgrading from 112488 (or lower) to 112488 (or higher),
all domains must undergo a setkeyswitch standby/on process for
the fix for Bug 4676870 to be put into effect.
COMMENTS:
None
============================================================================
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
support 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.
