Configure Virtual CIFS Servers
Configuration Overview
When CIFS is configured with HP Clustered File System and FS Option
for Windows, the data to be shared is stored on PSFS clustered
filesystems. A set of Virtual File Shares, one per node in the cluster, is
typically created for each filesystem.
FS Option for Windows uses “Virtual CIFS Servers” to provide CIFS
access to the Virtual File Shares. Clients access the Virtual File Shares via
the CIFS interface to those Virtual CIFS Servers; they do not need to know
which physical node is providing the service.
When you create a Virtual CIFS Server, you will need to assign it to a
primary node and one or more backup nodes. You can then add one or
more Virtual File Shares to the Virtual CIFS Server. Following are some
sample configurations.
Virtual CIFS Server Providing a Single File Share
The following example shows a Virtual CIFS Server providing the Virtual
File Share data1. In this example, the Virtual CIFS Server VFS1 is initially
active on the primary node; client requests for its Virtual File Shares go to
this node. FS Option for Windows periodically monitors the Virtual File
Shares to determine whether they can be accessed externally.
