Removal Procedure

1. Terminate all usage of devices on the board.

   See "Terminating I/O Devices".

2. Check the status of the board:

   • For a simple list containing board names, states, and conditions, enter:

     ---

     # cfgadm
     

     ---

   • For a more detailed list, enter:

     ---

     # cfgadm -v
     

     ---

   For a board removal or replacement, the states and conditions must be one of the following sets:

   • The board is ok:

     • Receptacle state--Connected

     • Occupant state--Configured

     • Condition--OK

   • The board is failing:

     • Receptacle state--Connected

     • Occupant state--Configured

     • Condition--Failing

3. Unconfigure the board:

   ---

   # cfgadm -c unconfigure sysctrl#:slot#
   

   ---

   For sysctrl#:slot# (the attachment point ID) use the board name that was listed in the status report of the previous step.

4. Use the cfgadm command to see if the board is unconfigured.

   If the unconfigure operation failed:

   1. See "Removing Boards that Use Detach-Unsafe Drivers".

   2. See "Quiescence".

   3. Resolve the problem.

   4. Unconfigure the board again (Step 3).

   ---

   Note -

   A failure of the unconfigure step results in a partially unconfigured condition. If this happens, attempt to unconfigure again. A configuration operation is not permitted at this point.

   ---

5. When the board is successfully unconfigured, you can do one of the following:

   • Leave the board in the system unconfigured

   • Configure the board

   • Logically disconnect the board, in preparation for removal:

     ---

     # cfgadm -v -c disconnect sysctrl#:slot#
     

     ---

6. The disconnection takes a few moments, so if you wish to remove the board from the card cage at this time, first verify the board status.

   1. Use cfgadm to verify that the board is logically disconnected.

   2. Check the LEDs on the board to verify that the board is electrically disconnected.

      The two outer LEDs must be off and the middle LED may be either lighted or off.

7. After you have verified that the board is disconnected, you may physically remove or replace the board (see "Installing a Replacement Board").

If you wish, you can leave the board in place until a later time.

If no replacement is available, leave the board in the slot, or fill the empty slot with a dummy board or a load board to maintain the proper flow of cooling air in the cardcage. For Enterprise 3000, 3500, 4000, 4500, 5000, and 5500 systems, use a dummy board. For Enterprise 6000 or 6500 systems, use a load board.
