How to Unconfigure an IB Port, HCA_SVC, or a VPPA Device

Use the following steps if you want to remove an IB Port, HCA_SVC, or a VPPA device from the system.

The example below illustrates how to unconfigure a VPPA device, but the same procedure applies to Port and HCA_SVC devices as well.

1. Become superuser.

2. Unconfigure the IB VPPA device.

   For example:

   # cfgadm -c unconfigure ib::1730000007F51,8001,ipib Unconfigure the device: /devices/ib:fabric::1730000007F51,8001,ipib This operation will suspend activity on the IB device Continue (yes/no)? Y #

3. Verify that the device is disconnected.

   For example:

   # cfgadm -a ib::1730000007F51,8001,ipib Ap_Id Type Receptacle Occupant Condition ib::1730000007F51,8001,ipib IB-VPPA connected unconfigured unknown #
