Chapter 3: Introduction to HP Clustered File System 12
HP Clustered File System Databases
HP Clustered File System uses the following databases to store cluster
information:
• Shared Memory Data Store (SMDS). The SANPulse process stores
filesystem status information in this database. The database consists of
sp_status files that are located in %SystemDrive%\Program
Files\Hewlett-Packard\HP Clustered File System\conf on each server.
These files should not be changed.
• Device database. HP Clustered File System uses a device database to
store the physical UID and a global device identifier for each disk
imported into the cluster. The database is located on the membership
partitions that you selected when installing HP Clustered File System.
The membership partitions are also used for functions related to SAN
control.
• Volume database. This database stores information about dynamic
volumes and is located on the membership partitions.
• mxds datastore. This database stores cluster configuration
information and is located on the membership partitions.
Virtual Hosts and Failover Protection
HP Clustered File System uses virtual hosts to provide failover protection
for servers and network applications.
A virtual host is a hostname/IP address configured on one or more servers.
The network interfaces selected on those servers to participate in the
virtual host must be on the same subnet. One server is selected as the
primary server for the virtual host. The remaining servers are backups.
The primary and backup servers do not need to be dedicated to these
activities; all servers can support other independent functions.
To ensure the availability of a virtual host, HP Clustered File System
monitors the health of all network interfaces and the health of the
underlying server. If you have created service or device monitors, those
monitors periodically check the health of the specified services or devices.
