Overview of HA HP CIFS Server
Highly Available HP CIFS Server allows the HP CIFS Server product to
run on a MC/ServiceGuard cluster of nodes. C/ServiceGuard allows you
to create high availability clusters of HP 9000 Server computers.
You must set up an MC/ServiceGuard cluster before you can set up an
HA HP CIFS Server. For instructions on setting up an MC/ServiceGuard
cluster, refer to the Managing MC/ServiceGuard manual.
The HA HP CIFS Server provides customizable configuration, control
scripts and monitor scripts. These scripts as well as this README file
are in the /opt/samba/HA directory. These are sample scripts for you to
customize for your environment.
Recommended Clients
The recommended clients for the HA HP CIFS Server are Windows 9x
and Microsoft NT/2000. Older clients, such as DOS/Windows 3.1 LM
2.2C and Windows for Workgroups, may not respond well to the HP CIFS
Server stopping and to network connections terminating, as occurs
during an HA HP CIFS Server switchover.
Review the “Special Notes for HA HP CIFS Server” section contained
later in this section for usage considerations.
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.
