Domains on Sun Fire 3800/4800/4810/4900/6800/6900 systems ... see below for details:

1. Impact

Domains on Sun Fire 3800/4800/4810/4900/6800/6900 systems with memory configurations of 1-way, 2-way or 4-way interleaving may experience a Domain pause.

2. Contributing Factors

This issue can occur on the following platforms:

SPARC Platform

Sun Fire 3800/4800/4810/4900/6800/6900

Platforms configured with two domains in one segment may experience this issue.

3. Symptoms

Should the described issue occur, messages similar to the following may be captured to the system controller logs or output to the domain console:

    /partition1/domain0/SB1/ar0:

Update information and add 3800/4800/4810/4900/6800/6900 systems to Synopsis and Contributing Factors

Date: 17-AUG-2004

Changed focus of content to outline "4 way interleave" process

Internal Comments

Engineering:

The workaround to this issue involves, possibly :

a) Reconfiguring DIMMs of a different capacity to ensure 8way or 16way interleave - this means Sun has to provide the customer with appropriate DIMM sizes to prevent running into 4 way interleave

b) Setting the interleave to "across-board" - but this violates Best Practices and also inhibits DR functionality. The memory interleave in a domain gets configured as 4 way if there is "uneven" DIMM configuration (mixed DIMMs) AND/OR having CPUs disabled

There is a firmware "fix" that is going into SCApp 5.18.0 which will be released sometime in OCT.
