Overview of HA HP CIFS Server Active-Active
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/active_active directory. These are sample
scripts for you to customize for your environment.
This README and the files in /opt/samba/HA/active_active only apply
to an active-active HA configuration. The equivalent files, which apply to
an active-standby HA configuration, are in the
/opt/samba/HA/active-standby directory.
IMPORTANT This active-active configuration scheme has been revised and now differs
from the scheme provided by initial HP CIFS Server releases. This
scheme allows for any number of cluster nodes. The templates are
simpler. This scheme also avoids confusion about netbios name to IP
address mapping and registration with WINS servers. This scheme
avoids the “ghost” session issues when packages are moved. As with the
previous scheme, the SWAT utility has limited capabilities in an HA
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.
