Your adapter is attempting to power down idle drives.  If you want to get rid of them (I've seen FreeBSD get very unhappy when you get too many transitions like this), go into the LSI WebBIOS (Ctl-H at boot), go to the adapter properties screen, and disable drive powersave mode.  The exact name of the property seems to vary from firmware to firmware.
