The Sun FireTM V880 software is included in the Solaris 9 12/03 release. When you install the Solaris 9 12/03 release on a Sun Fire V880 server, the V880 software attempts to load the bbc and gptwo drivers.
The fix for Bug 4717004 removed the bbc and gptwo drivers. Since these drivers have been deleted and are no longer available, the following error messages are displayed when you reboot the system:
WARNING: Failed to install "bbc" driver. WARNING: Failed to install "gptwo" driver.
Workaround: These messages are benign and can safely be ignored.
