Understanding the MC/ServiceGuard NFS Files

MC/ServiceGuard NFS uses files similar and typical to ServiceGuard. These include configuration files, control scripts, monitoring scripts, and templates. As is true for all ServiceGuard packages, you configure and view a small number of files. Two of these, nfs.mon and ha.nfs are new to MC/ServiceGuard NFS. The following is a brief description of the files:

Files that apply to the whole cluster:
- cluster configuration file, cluster.conf
  Defines the cluster nodes, shared networks, and max # of packages
- raidtab.sg
  Defines the HA storage devices (MDs) for all the packages.
- nfs.mon
  NFS monitoring script
Files that apply to each NFS package (<pkg>):
- package configuration file, <pkg>.conf
  The master package configuration file. It defines the package's nodes and failover behavior, and points to the package's control script, pkg.cntl.
- package control script, <pkg>.cntl
  This defines the start and stop behavior, especially the activation and de-activation of the HA storage, and calls hanfs.sh.
- NFS control script, hanfs.sh
  This exports the HA file system managed by this package. If specified, it also starts monitoring the NFS services.
- <pkg.cntl>.log and hanfs.sh.log files
  These are generated automatically.
