Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide

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

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

To create a SUNW.HAStorage resource hastorage-1 for new resources in resource-group-1, perform the following steps.

  1. Become superuser on a cluster member.

  2. Create the resource group resource-group-1.


    # scrgadm -a -g resource-group-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 resource-group-1 -t SUNW.HAStorage \

-x ServicePaths=/global/resource-group-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 resource-group-1, and set their dependency to hastorage-1.

    For example, for iWS, run the following command.


    # scrgadm -a -j resource -g resource-group-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 resource-group-1 to the managed state, and bring resource-group-1 online.


    # scswitch -Z -g resource-group-1

The SUNW.HAStorage resource type 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. See the SUNW.HAStorage(5) man page for details.
