Replacing a PCI hot-pluggable network interface card

Keep the following in mind before you replace a hot-pluggable PCI network interface card:

• Be aware of the following consideration: If a network interface you are hot-replacing is the only available keepalive path on the node where it resides, you must shut down PowerHA® SystemMirror® on this node in order to prevent a partitioned cluster while the interface is being replaced.
• SMIT gives you the option of stopping cluster services on this node with resource groups brought offline. From this point, you can manually hot-replace the network interface card.
• Hot-replacement of Ethernet network interface cards is supported.
• You should manually record the IP address settings of the network interface being replaced to prepare for unplanned failures.
• You should not attempt to change any configuration settings while the hot replacement is in progress.
• To avoid a network failure when using multiple dual-port Ethernet adapter cards on the same node for a particular network, you must configure the interfaces on different physical dual-port Ethernet adapter cards.
