Sun Enterprise 6x00, 5x00, 4x00, and 3x00 Systems Dynamic Reconfiguration User's Guide

Using this Guide

  1. Determine the name and status of the board or card cage slot. You will find it listed in the online DR status report. See "How to Monitor Board Status".

  2. In the following table, find the entry corresponding to the condition of the board or device, then go to the procedure or reference listed in the Service Reference column.

Table 2-1 DR Conditions

Condition 

 Explanation Service Reference

empty

No board is present in the slot. All LEDs are off. 

To install a board, see "Installing a New Board"

disconnected

A board is present but is electrically disconnected. The system is able to identify the board type. The board LEDs show that the board is in low power mode and can be unplugged at any time. 

LEDs: green, yellow , green (Off, On, Off) 

Use cfgadm -c disconnect to enable this state.

To remove a disconnected board, refer to the service manual for the system. To power up a disconnected board, see "Installing a New Board"

connected

The board is electrically connected and powered up. The system is actively monitoring the board for temperature and cooling. 

LEDs: green, yellow, green (On, Off, Off) 

Use cfgadm -c connect to enable this state.

To remove a connected board, see "Removing a Board". To use a connected board, see "Installing a New Board".

configured

Devices on the board are fully initialized and may be mounted or configured for use. The LEDs show the normal running pattern. 

LEDs: On, Off, Flash 

Use cfgadm -c configure to enable this state.

To remove a configured board, see "Removing a Board".

unconfigured

The unconfigured state covers all other device states, including receptacles in the empty state. The LED pattern is the same as for the connected receptacle state. 

LEDs: green, yellow, green (On, Off, Off) 

Use cfgadm -c unconfigure to enable this state.

To remove an unconfigured board, see "Removing a Board". To use an unconfigured board, see "Installing a New Board".

unknown

The current condition cannot be determined. This situation results either when a new board is inserted in a running system, or a board is placed on the disabled board list prior to a reboot. A transition to a connected receptacle state will change an attachment point condition from unknown to either OK or Failed. 

To use an unknown board, see "Installing a New Board"

ok

No problems have been detected. This condition can only occur after a board has been connected. This condition will persist either until the board is physically removed, or a problem is detected. An ok condition requires correct hardware compatibility, correct firmware revision, adequate power, adequate cooling, and adequate precharge. 

To remove an ok board, see "Removing a Board"

failing

A failing condition can only occur when a board that was in the OK condition develops a problem. For example, the board has begun to overheat. This condition will be displayed until the problem is corrected or the attachment point is disconnected.  

To remove a failing board, see "Removing a Board". To correct an overheating condition, see the system service manual.

failed

The board has failed POST/OBP. A failed condition may occur either during bootup or after a failed connect attempt. This condition is considered uncorrectable and will persist until the board is physically removed. For a failed attachment point condition, the receptacle state should never transition beyond disconnected. 

To remove a failed board, see "Removing a Board".

unusable

Either an attachment point has incompatible hardware, or an empty attachment point lacks power, cooling, or precharge current. An unusable condition is correctable. This condition is caused by one of the following events: (1) inadequate cooling in a slot, (2) power is detected in an empty slot, (3) a disconnected board has inadequate cooling, inadequate power, or unsupported hardware, or (4) firmware has detected a problem either during bootup or when a board is inserted.  

To remove a board from an unusable slot, see "Removing a Board". To correct overheating conditions in the slot, refer to the system service manual.
