replacement node. This information includes:
G
The IP address and network name of the client LAN adapters
G
For an Ethernet cluster interconnect, the IP address and network
name of the Ethernet cluster interconnect adapters
2.
If the new node will use applications or data that is stored locally on the
node being replaced, back up that data to a removable storage medium
or to a remote file server that can be restored onto the replacement node.
3.
Stop the Oracle instance on the node to be removed.
4.
Stop all Oracle services on the node to be removed.
5.
Shut down the server on that node and power it off.
6.
Disconnect the Fibre Channel cables between the evicted node and the
Storage Hubs or Fibre Channel SAN Switches.
7.
Disconnect the cluster interconnect cables from the evicted node and
label them as the cluster interconnect cables.
8.
Disconnect the client LAN cables from the evicted node and label them
as the client LAN cables.
9.
If adapters from the evicted node will be used in the new node, move the
adapters to the new node.
