■
The cluster interconnect must be on a separate subnet than the client
LAN. Check this by viewing the IP addresses assigned to all
interconnect adapters and to all client LAN adapters.
■
If Compaq Insight Manager is loaded and configured, use it to check the
operation statistics and possible error messages for the interconnect
adapter installed in each cluster node.
When Using the Ethernet Cluster Interconnect
■
Make sure that the Ethernet cluster interconnect components (adapters,
cables, switches or hubs) are properly installed as specified in Chapter 5,
“
Installation and Configuration.
”
■
Make sure that the Ethernet cluster interconnect and the client LAN are
connected to different Ethernet switches or hubs.
■
Use the ping utility to test the Ethernet cluster interconnect connections.
For information about the ping utility, refer to
“
Verifying Cluster
Communications
”
in Chapter 5,
“
Installation and Configuration.
”
■
Make sure that all Ethernet traffic not related to the Oracle data is using
the client LAN, not the cluster interconnect.
Unable to Ping the Cluster Interconnect or the
Client LAN
If you are using the recommended method of using static IP addresses, ensure
that the hosts file and lmhosts files are properly set up.
When Using the Ethernet Cluster Interconnect
■
Make sure that the Ethernet cables are properly connected and that the
Ethernet switches or hubs are powered on. In the redundant Ethernet
cluster interconnect, verify that all Ethernet adapters used as the primary
cluster interconnect path are connected to the same switch and that all
adapters used as the redundant cluster interconnect path are connected to
the redundant switch.
■
Make sure that the Ethernet drivers are properly installed and configured
on the cluster nodes. Verify the Ethernet drivers for the interconnect
adapters are the same revision level on all cluster nodes.
