How to Display PCI Slot Configuration Information

This procedure has been updated to include PCIe configuration information.

The cfgadm command displays the status of PCI hot-pluggable devices and slots on a system. For more information, see cfgadm(1M).

1. Become superuser.

2. Display PCI configuration information.

   • Display PCI slot configuration information.

     For example:

     # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected configured ok pci1:hpc0_slot4 unknown empty unconfigured unknown

   • Display specific PCI device information.

     For example:

     # cfgadm -s "cols=ap_id:type:info" pci Ap_Id Type Information pci1:hpc0_slot0 unknown Slot 7 pci1:hpc0_slot1 unknown Slot 8 pci1:hpc0_slot2 unknown Slot 9 pci1:hpc0_slot3 ethernet/hp Slot 10 pci1:hpc0_slot4 unknown Slot 11

     The logical Ap_Id, pci1:hpc0_slot0, is the logical Ap_Id for hot-pluggable slot, Slot 7. The component hpc0 indicates the hot-pluggable adapter card for this slot, and pci1 indicates the PCI bus instance. The Type field indicates the type of PCI adapter card that is present in the slot.

   • Display PCIe slot configuration information.

     For example:

     # cfgadm pci Ap_Id Type Receptacle Occupant Condition pcie1 unknown empty unconfigured unknown pcie2 unknown empty unconfigured unknown pcie3 unknown empty unconfigured unknown pcie4 etherne/hp connected configured ok pcie5 pci-pci/hp connected configured ok pcie6 unknown disconnected unconfigured unknown

   • Display specific PCIe device information.

     For example:

     # cfgadm -s "cols=ap_id:busy:o_state" pci Ap_Id Busy Occupant pcie1 n unconfigured pcie2 n unconfigured pcie3 n unconfigured pcie4 n configured pcie5 n configured pcie6 n configured

     ---

     Note –

     The logical Ap_Id in most cases should match the slot label that is silk-screened on the system chassis. Refer to your platform guide for the cfgadm output of the hot-pluggable slots. The Busy field can be displayed to ensure that the Ap_Id is not transitioning to another state before a hot-plug operation is attempted.
