HP Serviceguard NFS Toolkit

HP Serviceguard Network File Server (NFS) Toolkit (formerly MC/ServiceGuard NFS Toolkit) uses HP Serviceguard (formerly MC/ServiceGuard) to set up highly available NFS servers. An NFS server is a host that “exports” its local directories and makes them available for client hosts to mount using NFS. On the NFS client, these mounted directories look to users like part of the client's local file system. With HP Serviceguard NFS, the NFS server package containing the exported file systems can move to a different node in the cluster in the event of failure.

Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

Serviceguard NFS Toolkit A.11.31.02 contains the following changes from the September 2005 release of HP-UX 11i v1:

Serviceguard NFS Toolkit can work with Serviceguard A.11.17.01. Serviceguard A.11.17.01 is being released in the HP-UX 11i v3 (11.31) release.
Serviceguard A.11.17.01 provides a new control script template. Serviceguard NFS Toolkit supports the new variable HA_NFS_SCRIPT_EXTENSION in the control script (nfs.cntl). This new variable can be used to modify the name of the NFS specific control shell script (hanfs.sh) that is associated with a package.
Serviceguard A.11.17.01 introduces a new MULTI_NODE package type which is not supported by Serviceguard NFS Toolkit. The only supported package type is FAILOVER.
Serviceguard A.11.17.01 provides a new package configuration file template. The new package configuration file template introduces the following dependency variables:
- DEPENDENCY_NAME
- DEPENDENCY_CONDITION
- DEPENDENCY_LOCATION
The above parameters are not supported in Serviceguard NFS Toolkit A.11.31.02. By default, these variables are commented out in the nfs.conf file.
Serviceguard NFS Toolkit version A.11.31.02 does not support the following NFS HP-UX 11i v3 features:
- Secure NFS features, such as Kerberos and Diffie-Hellman public key.
- NFS Version 4 protocol
This release also provides a defect fix. See the product release notes for details.
