T5-4/T5-8 : PCIE fabric error panic or/and ereports on QLogic Fiber Channel HBA (Pallene) populated slots (Doc ID 1559361.1)

Last updated on APRIL 06, 2021

Applies to:

SPARC T5-4 - Version All Versions to All Versions [Release All Releases]
SPARC T5-8 - Version All Versions to All Versions [Release All Releases]


SPARC T5-4 and SPARC T5-8 systems configured with SG-XPCIE2FC-QF8-Z Qlogic 'Pallene' fiber channel HBAs may panic on a fabric error, referencing one of the Pallene populated slots, or report ereports on Pallene populated slots with the HBA running at PCIe Gen2.

++ PCIe panic ++

The stack may differ, however the common symptom will be various correctable events reported against installed QLogic 'Pallene' HBAs, for example; ena=2741168c7b21001 detector=[ version=0 scheme="dev"
 device-path="/pci@380/pci@1/pci@0/pci@a" ] bdf=250 device_id=80bf vendor_id=
 111d rev_id=3 dev_type=60 pcie_off=40 pcix_off=0 aer_off=100 ecc_ver=0
 pci_status=10 pci_command=147 pci_bdg_sec_status=0 pci_bdg_ctrl=3 pcie_status=
 1 pcie_command=12f pcie_dev_cap=8024 pcie_link_status=3042 pcie_dev_ctl2=0
 pcie_adv_ctl=1e5 pcie_ue_status=0 pcie_ue_mask=0 pcie_ue_sev=460031
 pcie_ue_hdr0=0 pcie_ue_hdr1=0 pcie_ue_hdr2=0 pcie_ue_hdr3=0 pcie_ce_status=
 1100 pcie_ce_mask=0 remainder=1 severity=3

++ Correctable PCIe events ++

This is the most common symptom and will report correctable errors against the HBA, for example from {snapshot}/fma/@usr@local@bin@fmdump_-ev.out;

++ PCIe link initialisation failures ++

Another common fault is a failure by HyperVisor to correctly train the PCI links during initialisation, for example from {snapshot}/fma/@usr@local@bin@fmdump_-ev.out;
