Sun Cluster Data Services Planning and Administration Guide for Solaris OS

ProcedureHow to Set Up the HAStoragePlus Resource Type for New Resources

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

Note –

To create a HAStoragePlus resource with Solaris ZFS (Zettabyte File System) as a highly available local file system seeHow to Set Up the HAStoragePlus Resource Type to Make a Local Solaris ZFS Highly Available section.

To create an HAStoragePlus resource hastorageplus-1 for new resources in resource-group-1, read Synchronizing the Startups Between Resource Groups and Device Groups and then perform the following steps.

To create an HAStoragePlus resource, see Enabling Highly Available Local File Systems.

  1. On a cluster member, become superuser or assume a role that provides solaris.cluster.modify and solaris.cluster.admin RBAC authorizations.

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


    # clresourcegroup create resource-group-1

  3. Determine whether the resource type is registered.

    The following command prints a list of registered resource types.


    # clresourcetype show | egrep Type

  4. If you need to, register the resource type.


    # clresourcetype register SUNW.HAStoragePlus

  5. Create the HAStoragePlus resource hastorageplus-1, and define the filesystem mount points and global device paths.


    # clresource create -g resource-group-1 -t SUNW.HAStoragePlus \
-p GlobalDevicePaths=/dev/global/dsk/d5s2,dsk/d6 \
-p FilesystemMountPoints=/global/resource-group-1 hastorageplus-1

    GlobalDevicePaths can contain the following values.

    • Global device group names, such as nfs-dg, dsk/d5

    • Paths to global devices, such as /dev/global/dsk/d1s2, /dev/md/nfsdg/dsk/d10

    FilesystemMountPoints can contain the following values.

    • Mount points of local or cluster file systems, such as /local-fs/nfs, /global/nfs

    Note –

    HAStoragePlus has a Zpools extension property that is used to configure zpools.

    The resource is created in the enabled state.

  6. Add the resources (Sun Java System Web Server, Oracle, and NFS) to resource-group-1, and set their dependency to hastorageplus-1.

    For example, for Sun Java System Web Server, run the following command.


    # clresource create  -g resource-group-1 -t SUNW.iws \
-p Confdir_list=/global/iws/schost-1 -p Scalable=False \
-p Network_resources_used=schost-1 -p Port_list=80/tcp \
-p Resource_dependencies=hastorageplus-1 resource

    The resource is created in the enabled state.

  7. Verify that you have correctly configured the resource dependencies.


    # clresource show -v resource | egrep Resource_dependencies

  8. Set resource-group-1 to the MANAGED state, and bring resource-group-1 online.


    # clresourcegroup online -M resource-group-1
Affinity Switchovers

The HAStoragePlus resource type contains another extension property, AffinityOn, which is a Boolean that specifies whether HAStoragePlus must perform an affinity switchover for the global devices that are defined in GLobalDevicePaths and FileSystemMountPoints extension properties. For details, see the SUNW.HAStoragePlus(5) man page.

Note –

The setting of the AffinityOn flag is ignored for scalable services. Affinity switchovers are not possible with scalable resource groups.
