On Sun Enterprise 6000 and 6500 systems, the unconfigure operation fails for an I/O board in slot 15.
The "central" I/O board cannot be removed under Dynamic Reconfiguration. On Sun Enterprise x000 and x500 systems the lowest-numbered I/O board is considered a key resource and cannot be removed.
The PCI I/O board (type 3 I/O board) experiences Privileged Timeout Error during connect. The PCI I/O board is therefore not supported at this time.
