Configuring HA HP CIFS
Overview of HA HP CIFS Server Active-Active
Chapter 7 169
Installing Highly Available HP CIFS Server
HA HP CIFS Servers must be installed and configured on all cluster
nodes in the Active-Active configuration. All cluster nodes act as
“primary” nodes and, at the same time, as “alternate” nodes for others. If
there is no failover, each cluster node runs one of the packages. If a
failover occurs, a cluster node will pick up the failed package in addition
to its original package.
Before creating a Highly Available HP CIFS Server package, you must
set up your MC/ServiceGuard cluster according to the instructions in the
Managing MC/ServiceGuard manual.
To do so, perform the following:
1. Following the instructions, configure the disk hardware for high
availability.
2. Use SAM or LVM commands to set up the volume groups, logical
volumes, and file systems needed for the data that must be available
to the primary and alternate cluster nodes when failover occurs.
HA HP CIFS Server Installation
1. Install HP CIFS Server using SD on all cluster nodes. If HP CIFS
Server is already installed and configured on either node, simply stop
it with the /opt/samba/bin/stopsmb command and skip to step 4.
2. On the first node:
Run the script /opt/samba/bin/samba_setup to configure the
Samba server. Enter the server name and domain/workgroup name
for the HA HP CIFS Server.
3. On the secondary nodes:
Run the script /opt/samba/bin/samba_setup to configure the second
node. You will need to specify the same domain/workgroup name
specified on the first node. Do not use the same server name.
4. For any UNIX users used to authenticate CIFS clients, check that
they have the same name, user ID number, primary group and
password on both of the nodes.
This is required for any users used to authenticate to either Samba
server in the Active-Active configuration. This means that any user
name used on both Samba servers must have the same user ID,
