Issue
The FAS9000 or AFF-A700 systems triggers a PCI NMI error and results in a system reboot
- The Service Processor (SP) system log displays the following error:
Example:
Panic String: PCI Error NMI from device(s):ErrSrcID(CorrSrc(0x8460),UCorrSrc(0)), RPT(128,2,0):PLX PCIE 8780 switch on Controller, Br[8780](132,12,0): Link down. in process idle: cpu24 on release 9.6P3 (C)
-
From the "
sysconfig -PCI" command output, it is determined that the link was down between the Motherboard and the card in slot 7.
Example:
Br[8780](132,12,0): PLX PCIE 8780 switch on Controller
LinkCap(MaxLkSp(3),MaxLkWd(16),ASPM(2),L0(6),L1(2),SurpDn,DLAct,Port(12))
LinkStatus(LkSp(3),LkWd(16),DLAct),
Br[8732](137,0,0) in slot 7: PLX PCIE 8732 switch in slot 7 on Controller
LinkCap(MaxLkSp(3),MaxLkWd(16),ASPM(2),L0(6),L1(2),Port(0))
LinkStatus(LkSp(3),LkWd(16)),
- "
sysconfig -ac" shows details of the card in slot 7.
Example:
sysconfig: slot 1 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
sysconfig: slot 2 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
sysconfig: slot 3 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
sysconfig: slot 4 OK: X91440A: 40G high performance
sysconfig: slot 6 OK: X93140A: NetApp NVRAM10
sysconfig: slot 7 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
sysconfig: slot 9 OK: X92071A: PMC PM8072; PCI-E quad-port SAS (PM8072)
sysconfig: slot 10 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
sysconfig: slot 11 OK: X91143A: Qlogic EP8324 Quad-Port 16Gb FC/10GbE PCIe CNA
- The CNA card in the slot is replaced, and at some point afterwards the controller panics again with the same panic string from the same slot
