Solution Type Sun Alert Sure Solution 1000142.1 : Sun Fire 12K/15K/E20K/E25K Systems Equipped With a Quad GigaSwift (QGE-X) Card May Panic
PreviouslyPublishedAs 200188 Bug Id <SUNBUG: 6624392> Product Sun Fire 12K Server Sun Fire E20K Server Sun Fire 15K Server Sun Fire E25K Server Date of Workaround Release 26-SEP-2007 Date of Resolved Release 21-Aug-2008 Impact Sun Fire 12K/15K/E20K/E25K systems equipped with UltraSPARC IV or UltraSPARC IV+ System Boards that use high traffic across a Quad GigaSwift (QGE-X) card may panic. Contributing FactorsThis issue can occur on the following platforms:
The described issue only occurs under the following conditions: 1. The Sun Fire 12K/15K/E20K/E25K is equipped with an UltraSPARC IV or UltraSPARC IV+ System Board, and the Quad GigaSwift Ethernet PCIX Card (X4445 - 501-6738) 2. One of the network ports is at or near its peak bandwidth. 3. The network card is running at a frequency over 66MHz. Note: The more CPU's in a domain, the more likely the panic may occur while the network port is at its peak bandwidth. This issue has not been seen on systems equipped with the UltraSPARC III system boards. To determine if a system is equipped with a Quad GigaSwift Ethernet PCIX Card (X4445 - 501-6738), the following command can be used: # prtdiag Symptoms If the described issue occurs, a panic string of "Fatal PCI bus error(s)" will be seen. WorkaroundTo work around the described issue, slow down the QGE-X card to use PCI speeds instead of PCIX. This is done by adding a post directive to the "postrc" file on the system controller. The "postrc" file is different for each domain. If there is not a "postrc" file for a specific domain, the platform "postrc" file is used. The domain "postrc" files are located at: /etc/opt/SUNWSMS/config/A/.postrc The platform "postrc" file is located at: /etc/opt/SUNWSMS/config/platform/.postrc The postrc directive is a single line that is added to this file. The syntax is: iobrd_no_pcix exp [ lport [ bus ]] Use this "postrc" directive for every QGE-X card that is in the platform. Below is an example of the postrc directive and its syntax for each slot: iobrd_no_pcix 3 0 0 # changes IOBoard Slot 0 on IO3. Note: Slot 1 is not a PCIX slot and is not impacted by this issue.
