each node,

modify the

/etc/hosts

file by adding the following lines.

NOTE: The examples in this and the following step are for a two-node configuration; add lines for each

additional cluster node.

each node

, create or modify the

/etc/hosts.equiv

file by listing all of your public IP addresses or host

names. For example, if you have one public hostname, one virtual IP address, and one virtual hostname

for each node, add the following lines:

<public hostname node1> oracle

<public hostname node2> oracle

<virtual IP or hostname node1> oracle

<virtual IP or hostname node2> oracle

As the user

, connect to each node to verify that remote shell (

rsh

) is working by typing

rsh

<public

, where

is the node number.

Verifying the Storage Configuration

During the cluster configuration described in this document, you will create partitions on your Fibre

Channel storage. In order to create the partitions, all cluster nodes must be able to detect the external

storage devices. To verify that each node can detect each storage LUN or logical disk, perform the following

steps:

For Dell | EMC Fibre Channel storage, verify that the EMC Navisphere

agent and the correct

version of PowerPath (see Table 1-6) are installed on each node, and that each node is assigned to the

correct storage group in your EMC Navisphere software. See the documentation that came with your

Dell | EMC Fibre Channel storage for instructions.

NOTE: The Dell Professional Services representative who installed your cluster performed this step. If you

reinstall the software on a node, you must complete this step.

Visually verify that the storage devices and cluster nodes are connected correctly to the Fibre Channel

switch (see Figure 1-1 and Table 1-4).

Verify that you are logged in as
