How to Set Up SUNW.HAStorage Resource Type for New Resources

In the following example, the resource group rg-1 contains three data services:

• iWS, which depends on /global/rg-1

• Oracle, which depends on /dev/global/dsk/d5s2

• NFS, which depends on dsk/d6

To create a SUNW.HAStorage resource hastorage-1 for new resources in rg-1, do the following:

1. Become superuser on a node in the cluster.

2. Create the resource group rg-1.

   # scrgadm -a -g rg-1

3. Register the resource type.

   # scrgadm -a -t SUNW.HAStorage

4. Create the SUNW.HAStorage resource hastorage-1 and define the service paths.

   # scrgadm -a -j hastorage-1 -g rg-1 -t SUNW.HAStorage \ -x ServicePaths=/global/rg-1,/dev/global/dsk/d5s2,dsk/d6

   ServicePaths can contain the following values:

   • Global device group names, such as nfs-dg

   • Paths to global devices, such as /dev/global/dsk/d5s2 or dsk/d6

   • Cluster file system mount points, such as /global/nfs

5. Enable the hastorage-1 resource.

   # scswitch -e -j hastorage-1

6. Add the resources, iWS, Oracle, and NFS, to rg-1 and set their dependency to hastorage-1. For example, for iWS, type:

   # scrgadm -a -j resource-name -g rg-1 -t SUNW.iws \ -x Confdir_list=/global/iws/schost-1 \ -y Scalable=False -y Network_resources_used=schost-1 \ -y Port_list=80/tcp -y Resource_dependencies=hastorage-1

7. Set rg-1 to the managed state and bring it online.

   # scswitch -Z -g rg-1

SUNW.HAStorage contains another extension property, AffinityOn, which is a Boolean that specifies whether SUNW.HAStorage must perform an affinity switchover for the global devices and cluster file systems defined in ServicePaths. For details, see the SUNW.HAStorage(5) man page.
