Dynamic Reconfiguration Release Notes

Dynamic reconfiguration (DR) on Sun Fire high-end systems consists of two parts. One part runs with SMS on the system controller (SC), and this chapter contains release notes pertaining to that part for the SMS 1.4 release. The other part runs on the domain side and release notes about that portion are included in the appropriate version of Solaris Release Notes Supplement for Sun Hardware.

Note - This information is correct as of the printing date of this document. For the latest information, please also see http://www.sun.com/servers/highend/dr_sunfire/slot1_dr.html.

Known Limitations

By default, using a MAXCPU board in a split slot configuration is not allowed. If you need this configuration because you are upgrading from SMS 1.3 where the configuration was allowed, contact your Sun Service Representitve and refer to RFE number #4863496.

Slot 1 DR

Sun Fire high-end systems support up to 18 expander boards, each of which includes two slots. Slot 0 is the upper assembly, which contains a CPU/Memory board, and Slot 1 is the lower assembly. At the time of this publication, Slot 1 could contain either a MaxCPU board or a hsPCI assembly.

Solaris 9 4/03 is the first Solaris 9 release to support DR operations on a board in Slot 1, and Solaris 8 2/02 with certain patches is the first Solaris 8 release to support it. Domains running the base Solaris 9 release continue to support DR on CPU/Memory boards. In both cases, SMS 1.3 or SMS 1.4 is required. For more information and the required Solaris 8 patch numbers, see http://www.sun.com/servers/highend/dr_sunfire/slot1_dr.html.

DR Documentation Notes

For release notes that pertain to DR on the domain side, see the Solaris Release Notes Supplement for Sun Hardware that corresponds to the Solaris version running on your domains. That document accompanies each Solaris release and update. Also, see http://www.sun.com/servers/highend/dr_sunfire/slot1_dr.html.

Known Bugs

This section contains important SMS-side bugs that involve DR on the Sun Fire high end system.

DCA Doesn't Detect Failed Network Connection (BugId 4628314)

DCA doesn't detect a failed network connection, which can cause a DR command to hang.

Workaround: Kill any of the following remote DR commands that appear to be hung:

A Valid MaxCPU Board Used In An Invalid Split-Slot Configuration Will Fail POST (BugId 4904620)

DR of a board with "Test Status" of Failed will fail with "Insufficient Condition" unless board is powered cycled.

Workaround: Power cycle the board.

Known Hardware Bugs

GigaSwift Ethernet MMF Link Goes Down With CISCO 4003 Switch After DR Attach (BugId 4709629)

Attempting to execute a DR operation on a system with Sun GigaSwift Ethernet MMF Option X1151A, part number 595-5773, attached to certain CISCO switches causes the link to fail. The problem is caused by a known bug in the following CISCO hardware/firmware:

CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 4.4(1))

CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 7.1(2))

CISCO WS-c5500 switch (f/w: WS-C5500 Software, Version McpSW: 4.2(1) and NmpSW: 4.2(1))

This problem is not seen on CISCO 6509 switch.

Workaround: Use another switch or consult Cisco for a patch.
