UFS Logging has been a standard part of Solaris since Solaris 7. All you
do to enable it is to mount your partitions with the "logging" option (man
mount_ufs for details). You can turn logging on for all filesystems,
including the root filesystem. Just add "logging" to the last field in
/etc/vfstab for all your UFS filesystems and reboot. For general, typical
use, I wouldnt bother with the metratrans that comes with SDS. That's
pretty much for Solaris 2.6 and below systems, and the rare case where you
want your logging on another spindle for performance reasons.

SunPC is not supported in S8. SunPC has been superceeded by the SunPCI
product (no more Sbus x86 cards)
