Sun Microsystems Netra CT Service Manual page 262

Cause
A CompactPCI card that is probably damaged was installed into an I/O slot in the
system. The card has some sort of error causing it to continually interrupt the CPU
with hot swap service events when there is no change to the board's state. The card
continually reports itself 'inserted' after it has already been acknowledged. Since no
board is 'claiming' the event, no slot # can be given. Also see Section , "scsb#0: Bad
(non friendly ?) Board in Slot # ? Taking it Offline." on page C-4.
Action
Remove the I/O card from the server using the instructions in Chapter 6. If the error
message repeats, the system controller board may have failed. Try replacing the
system controller board using the instructions in Section 8.2, "System Controller
Board" on page 8-6.
scsb#0: hsc_restore: Cannot reset disconnected slot #
Cause
The system controller board was installed in the server while the amber Okay to
Remove LED was ON for an I/O slot.
Action
Enable basic hot swap on all the I/O slots in the server using the instructions in
Chapter 5. Once basic hot swap is enabled on all I/O slots, remove the system
controller board from the server.
