IA: 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 cfgadm to check the current receptacle and occupant state and make sure the ap_id is correct.

Error Message

cfgadm: Attachment point not found

Cause

Specified attachment point was not found.

Solution

Check whether the attachment point is correct. Use cfgadm 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-plug operations. The prtconf(1M) command displays whether or not Solaris recognizes the hardware. After inserting hardware, use the prtconf command to verify that the hardware is recognized. After a configure operation, use the prtconf -D command to verify the driver is attached to the newly installed hardware device.
