Scenario 1 (Live NICs only)

Edit online

This scenario discusses hot-replacing a live PCI network service or boot interface.

About this task

Complete the listed steps in the procedure when hot-replacing the following:
  • A live PCI network service interface in a resource group and with an available boot interface
  • A live PCI network service interface not in a resource group and with an available boot interface
  • A live PCI network boot interface with an available boot interface.

Procedure

  1. On the node for which you want to replace a hot-pluggable PCI network interface card, enter smit sysmirror.
  2. In SMIT, select System Management (C-SPOC) > Communication Interfaces > PCI Hot Plug Replace a Network Interface Card and press Enter.

    SMIT displays a list of available PCI network interfaces that are hot-pluggable.

  3. Select the network interface you want to hot-replace. Press Enter. The service address of the PCI interface is moved to the available boot interface.
  4. SMIT prompts you to physically replace the network interface card. After you have replaced the card, you are asked to confirm that replacement has occurred.

    If you select yes, the service address will be moved back to the network interface that has been hot-replaced. On aliased networks, the service address will not move back to the original network interface, but will remain as an alias on the same network interface. The hot-replacement is complete.

    If you select no, you must manually reconfigure the interface settings to their original values:

    1. Run the drslot command to take the PCI slot out of the removed state.
    2. Run the mkdev command on the physical interface.
    3. Use the ifconfig command manually as opposed to the smit chinet command, the cfgmgr command, or the mkdev command in order to avoid configuring duplicate IP addresses or an unwanted boot address.
