Serviceguard NFS Toolkit Overview HP Serviceguard Network File Server (NFS) Toolkit uses HP Serviceguard to set up highly available NFS servers. You must set up a Serviceguard cluster before you can set up Highly Available (HA) NFS. Serviceguard NFS Toolkit is a separately purchased set of configuration files and control script, which you can customize for your specific needs. An NFS server is a host that exports its local directories and makes them available for client hosts to mount using NFS.
Announcement Serviceguard NFS Toolkit A.11.31.05 supports Serviceguard A.11.18 and the Veritas Cluster File System (CFS). In a CFS environment, all nodes in the Serviceguard cluster can concurrently access the files in the CFS. The NFS servers in the cluster can concurrently access and export directories in the CFS. As a result, CFS enables NFS clients (typically located outside the cluster) to concurrently use multiple NFS servers to access files.
Limitations The following lists the limitations of using Serviceguard NFS Toolkit A.11.31.05 with Serviceguard A.11.18 and CFS: • Lock coherency for multiple NFS servers is not supported. NFS file lock coherency is not supported when multiple NFS servers are concurrently accessing a file. Lock operations do not return an error, but lock coherency is not guaranteed. This may cause data corruption or cause an application to hang.
New and Changed Features in This Version This release contains the following new enhancements and changes: Serviceguard NFS Modular Package support Serviceguard NFS Toolkit A.11.31.05 supports the modular package feature with Serviceguard A.11.18 and later. The Serviceguard NFS Modular package feature provides a new interface for configuring Serviceguard NFS packages, where all the package parameters are configured in one package configuration file.
New Fixes in Version A.11.31.05 There are no new defect fixes in Serviceguard NFS Toolkit A.11.31.05 version. Compatibility Information and Installation Requirements This section describes the compatibility information and installation requirements for the HP-UX 11i v3 September 2009 release. For specific installation instructions, see Serviceguard NFS Toolkit A.11.11.06, A.11.23.05 and A.11.31.05 Administrator's Guide HP-UX 11i v1, v2 and v3 Serviceguard NFS Toolkit A.11.31.
NOTE: This problem impacts only HA NFS server systems running AutoFS. You can safely use AutoFS on client systems. Cause HA NFS uses relocatable IP addresses that migrate from a primary NFS server to an adoptive node during a fail-over event. If you start AutoFS on an HA NFS server after Serviceguard is running, these relocatable IP addresses are included in AutoFS' list of local IP interfaces.
