x86: Troubleshooting PCI Configuration Problems

Error Message

cfgadm: Configuration operation invalid: invalid transition

Cause

An invalid transition was attempted.

Solution

Check whether the cfgadm -c command was issued appropriately. Use the cfgadm command to check the current receptacle and occupant state and to make sure that the Ap_Id is correct.

Error Message

cfgadm: Attachment point not found

Cause

The specified attachment point was not found.

Solution

Check whether the attachment point is correct. Use the cfgadm command to display a list of available attachment points. Also check the physical path to see if the attachment point is still there.

In addition to the cfgadm command, several other commands are helpful during hot-pluggable operations. The prtconf command displays whether Solaris recognizes the hardware. After adding hardware, use the prtconf command to verify that the hardware is recognized. After a configure operation, use the prtconf -D command to verify that the driver is attached to the newly installed hardware device.
