Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i and Windows 2000 Administrator Guide
Replacing a Cluster Node
Before replacing a node, verify that the new configuration is supported by the
PDC/O1000 cluster. To determine if your new server is supported, see the
Compaq Parallel Database Cluster Model PDC/O1000 Certification Matrix
for Windows 2000
at
www.compaq.com/solutions/enterprise/ha-pdc.html
IMPORTANT:
With some possible exceptions, the servers in the cluster must be set up
identically. For example, this means using one server model for all nodes. The cluster
components common to all nodes in the cluster must be identical; for example, the
cluster interconnect adapters, amount of memory, cache, and number of CPUs must be
the same in each cluster node.
Replacing a node consists of removing it logically from the cluster, removing
it physically from the cluster, then adding a new server to take its place.
Removing the Node
1.
Record pertinent information that will be needed when configuring the
replacement node. Such 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 cable installed between each Fibre Host
Adapter in the evicted node and its Fibre Channel SAN Switch, FC-AL
Switch, or Storage Hub.
