When multiple Open Access boards are installed on some Multi-Root PCI bus SPARC® Solaris™ 64-bit chassis, such as the Netra™ 440, some of the boards may be assigned identical bus and slot numbers.
NA2005-1 SP2 introduces support for these types of chassis, but the following actions should be taken.
For AG boards:
If only one type of board is being used in the system (all AG or all CG), the respective drivers will sort the numbering out by themselves.
In the case of mixed boards (AG and CG in the same chassis), the AG driver needs to adopt a different board numbering scheme. The following line should be added to /usr/kernel/drv/aghw.conf :
bus_offset=170;
This will force the aghw driver to use different numbering scheme.
Reboot the system
Use blocate instead of pciscan .
For CG boards:
Use cg6ktool -A to gather virtual bus numbers instead of pciscan
