Using SAMBA Toolkit in a Serviceguard Cluster README Revision: B.06.00

using a combination of shared and local storage, or using shared
storage only. The choice of local or shared storage is left to the
user's discretion. However, shared storage is recommended, as it is
easier to maintain.
Local Configuration
In a typical local configuration, identical copies of the HP CIFS
Server configuration files reside in exactly the same locations on
the local file system on each node. All HP CIFS Server file systems
are shared between the nodes. It is the responsibility of the
toolkit administrator to maintain identical copies of the HP CIFS
Server components on all nodes. If the file system that is getting
shared allows only read operations then local configuration is easy
to maintain. But if the file system allows write operations also,
it is the administrator's responsibility to propagate updates to all
the package nodes.
Shared Configuration
In a typical shared configuration, the HP CIFS Server file systems
and configuration files are all on the shared storage. The same HP
CIFS Server file systems and configuration files are shared between
the cluster nodes, so there is no need to maintain identical copies
of configuration files on each node.
In a cluster environment each HP CIFS Server instance should have
unique IP addresses. One or more relocatable IP addresses are created
for each HP CIFS Server when the package is created. When the HP CIFS
Server package is switched over from one node to another, this
particular instance is stopped, IP addresses are removed from the
primary node, IP addresses are reallocated to a standby node, and the
instance is started on that node. Clients will then be automatically
connected or manually reconnected through these IP addresses to the
identical HP CIFS Server file systems on the standby node.
Multiple HP CIFS Server Instances Configuration
The HP CIFS Server server permits multiple instances of its NetBIOS
and SMB master daemons.
Each HP CIFS Server has its own smb.conf file to define its
configuration. The NetBIOS name and IP address that the client
connects to will determine which smb.conf file is used to serve that
connection. This multiple HP CIFS Server master daemon
configuration allows CIFS Server to run multiple Serviceguard
packages simultaneously.
B. Setting Up the Application
Before configuring the Serviceguard package, the following
configuration tasks must be performed for the application:
