Installing and Configuring MC/ServiceGuard NFS

Installing MC/ServiceGuard NFS

Installing MC/ServiceGuard NFS

MC/ServiceGuard NFS Toolkit requires MC/ServiceGuard A.11.13 (or above). To enable the File Lock Migration feature (available with 11i v1 and 11i v2), you need MC/ServiceGuard A.11.15.

To ensure that the File Lock Migration feature functions properly, install HP-UX 11i v1 NFS General Release and Performance Patch, PHNE_26388 (or a superseding patch). For HP-UX 11i v2, the feature functions properly without a patch.

Use the HP-UX Software Distributor (SD) to install the MC/SG NFS file set. The following command starts the SD swinstall utility:

/usr/sbin/swinstall

The Software Distributor is documented in Managing HP-UX Software with SD-UX.

The files are installed in the /opt/cmcluster/nfs directory. The following files are part of the toolkit:

README

Description of the toolkit contents

hanfs.sh

The NFS specific control script

nfs.mon

The monitor script

nfs_xmnt

A script for handling cross-mounted NFS server

 

packages

nfs.flm

The file lock migration script (available with 11i v1 and

 

11i v2)

If the MC/ServiceGuard NFS package has previously been installed, the files are in /opt/cmcluster/nfs. Use swremove to remove these files before installing the latest version of MC/ServiceGuard NFS.
