Oracle^® Solaris Cluster 4.3 Data Services Planning and Administration Guide

How to Configure a Scalable Application Using the ScalMountPoint Resource

Before You Begin

This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical.

To perform this procedure, assume the root role that provides solaris.cluster.read and solaris.cluster.modify RBAC authorization.

1. Create a scalable resource group containing the ScalMountPoint resource for the NAS NFS file system.

   # clresourcegroup create -p RG_mode=Scalable \
   -p Desired_primaries=num_active_primary \
   -p Maximum_primaries=max_num_active_primary scalmp-rg

   # clresourcetype register SUNW.ScalMountPoint

   # clresource create -g scalmp-rg -t SUNW.ScalMountPoint \
   -p TargetFileSystem=nas_device:path \
   -p FileSystemType=nas \
   -p MountPointDir=fs_mountpoint scalmp-rs

   # clresourcegroup online -eM scalmp-rg

2. Create a scalable resource group that contains the application resource.

   # clresourcegroup create -p RG_mode=Scalable \
   -p Maximum_primaries=max_num_active_primary \
   -p Desired_primaries=num_active_primary \
   -p rg_affinities=++scalmp-rg app-rg

   The application resource group must have a strong positive affinity upon the resource group created in Step 1.

   # clresourcetype register app_resource_type
   # clresource create -g app-rg -t app_resource_type \
   …
   -p Scalable=True \
   -p resource_dependencies_offline_restart=scalmp-rs app-rs
   # clresourcegroup online -eM app-rg

   The application resource must have an offline restart dependency upon the ScalMountPoint resources created in Step 1.
