How to Resolve a Failed SCSI Unconfigure Operation

Use this procedure if one or more target devices are busy and the SCSI unconfigure operation fails. Otherwise, future dynamic reconfiguration operations on this controller and target devices will fail with a dr in progress message.

1. Become superuser, if not done already.

2. Type the following command to reconfigure the controller.

   # cfgadm -c configure device-name

IA: PCI Hot-Plugging With the cfgadm Command

This section provides step-by-step instructions for hot-plugging PCI adapter cards on IA based systems.

In the examples, only PCI attachment points are listed, for brevity. The attachment points that are displayed on your system depend on your system configuration.

IA: How to Display PCI Slot Configuration Information

The cfgadmin command displays the status of PCI hot-pluggable devices and slots on a system. For more information, see cfgadm(1M).

1. Become superuser.

2. Display PCI slot configuration information.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected configured ok pci1:hpc0_slot4 unknown empty unconfigured unknown

   Display specific PCI device information.

   # cfgadm -s "cols=ap_id:type:info" pci Ap_Id Type Information pci1:hpc0_slot0 unknown Slot 7 pci1:hpc0_slot1 unknown Slot 8 pci1:hpc0_slot2 unknown Slot 9 pci1:hpc0_slot3 ethernet/hp Slot 10 pci1:hpc0_slot4 unknown Slot 11

The logical Ap_Id, pci1:hpc0_slot0, is the logical Ap_Id for hot-pluggable slot, Slot 7. The component hpc0 indicates the hot-pluggable adapter card for this slot, and pci1 indicates the PCI bus instance. The Type field indicates the type of PCI adapter card that is present in the slot.

IA: How to Remove a PCI Adapter Card

1. Become superuser.

2. Determine which slot the PCI adapter card is in.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected configured ok pci1:hpc0_slot4 unknown empty unconfigured unknown

3. Stop the application that has the device open.

   For example, if the device is an Ethernet card, use the ifconfig command to bring down the interface and unplumb the interface.

4. Unconfigure the device.

   # cfgadm -c unconfigure pci1:hpc0_slot3

5. Confirm that the device has been unconfigured.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected unconfigured unknown pci1:hpc0_slot4 unknown empty unconfigured unknown

6. Disconnect the power to the slot.

   # cfgadm -c disconnect pci1:hpc0_slot3

7. Confirm that the device has been disconnected.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp disconnected unconfigured unknown pci1:hpc0_slot4 unknown empty unconfigured unknown

8. Open the slot latches and remove the PCI adapter card.

IA: How to Add a PCI Adapter Card

1. Become superuser.

2. Identify the hot-pluggable slot and open latches.

3. Insert the PCI adapter card into a hot-pluggable slot.

4. Determine which slot the PCI adapter card is in once it is inserted. Close the latches.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp disconnected unconfigured unknown pci1:hpc0_slot4 unknown empty unconfigured unknown

5. Connect the power to the slot.

   # cfgadm -c connect pci1:hpc0_slot3

6. Confirm that the slot is connected.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected unconfigured unknown pci1:hpc0_slot4 unknown empty unconfigured unknown

7. Configure the PCI adapter card.

   # cfgadm -c configure pci1:hpc0_slot3

8. Verify the configuration of the PCI adapter card in the slot.

   # cfgadm Ap_Id Type Receptacle Occupant Condition pci1:hpc0_slot0 unknown empty unconfigured unknown pci1:hpc0_slot1 unknown empty unconfigured unknown pci1:hpc0_slot2 unknown empty unconfigured unknown pci1:hpc0_slot3 ethernet/hp connected configured unknown pci1:hpc0_slot4 unknown empty unconfigured unknown

9. Configure any supporting software if this device is a new device.

   For example, if this device is an Ethernet card, use the ifconfig command to set up the interface.
