Solution Type Technical Instruction Sure Solution 1008075.1 : Sun Fire[TM] E25K, E20K, E15K, E12K : BERR panic events off PCI-X/PCI Quad Gigaswift ethernet card installed on schizo based hsPCI slot
PreviouslyPublishedAs 211118 Description This document discusses Bus Error panic events ( BERR ) observed on Sun Fire [TM] E25K, E20K, E15K, E12K resident domains deployed with PCI-X/PCI Quad Gigaswift ethernet card(s) ( X4445 ). This specific anomaly is observed on domain environments running Solaris[TM] 8 and where the PCI-X/PCI Quad Gigaswift ethernet card(s) is resident in Hot Swap PCI (hsPCI) I/O Board. Steps to Follow Sun Fire[TM] E25K, E20K, E15K, E12K : BERR panic events off PCI-X/PCI Quad Gigaswift ethernet card installed on schizo based hsPCI slot For example, the BERR panic event as reproduced in a Solaris[TM] 8 domain environment resident in a Sun Fire 15000 platform loaded with the Solaris 8 KU, 117350-39 & ce driver patch, 111883-34 ( which deploys CE Ethernet Driver v1.154 ) : /IO14/C5V0 PCI 476 B 33 33 1,0 ok pci-pci8086,537c.7/network (netw+ pci-bridge /IO14/C5V0 PCI 476 B 33 33 0,0 ok network-pci100b,35.30 SUNW,pci-x-qge /IO14/C5V0 PCI 476 B 33 33 1,0 ok network-pci100b,35.30 SUNW,pci-x-qge /IO14/C5V0 PCI 476 B 33 33 2,0 ok network-pci100b,35.30 SUNW,pci-x-qge /IO14/C5V0 PCI 476 B 33 33 3,0 ok network-pci100b,35.30 SUNW,pci-x-qge PCI-X/PCI Quad Gigaswift ethernet card ( X4445 ) deployed at IO14 slot C5V0. The BERR panic event reproduced in the above domain OS environment is reported as follows : WARNING: [AFT1] Bus Error (BERR) Event detected by CPU515 Privileged Data Access at TL=0, errID 0x00000479.9d38b088 AFSR 0x00100800 Product Sun Fire E25K Server Sun Fire E20K Server Sun Fire 15K Server Sun Fire 12K Server Internal Comments Another workaround solution against the above described BERR panic condition is: A binary CE driver on Solaris 8, version v1.158, derived from the fix proposed for the CR 6385683 ( 25K panics with Schizo and XMITS cards when testing fix for IB ), has also been successfully verified as providing redress against this BERR panic condition : i.e., 95 7823a000 57a7e 67 1 ce (CE Ethernet Driver v1.158) The above binary CE driver on Solaris 8 was verified on the same Solaris 8 environment used to reproduce the BERR panic events and from all indications, the new CE binary have successfully addressed the BERR panics encountered whilst using the original ce driver ( v1.154 .. aka 111883-34 ) . Please note that Solaris 8 is in Sun EOL Phase 2 (Limited Support). see Bug Id: 6456611 and 6385683 fixed in Solaris 9 112817-29 and Solaris 10 118777-08 111883, ce, berr, solaris 8, qge-x, qge, hspci, schizo, x4445, x4444, afar, starcat, amazon, 6456611, 6385683, 1.154, 1.158 Previously Published As 87034 Attachments This solution has no attachment |
