Sun Cluster 3.1 Release Notes

End-of-Feature-Support Statements

Public Network Management (PNM)

Public Network Management (PNM) is not supported in Sun Cluster 3.1. Software Network adapter monitoring and failover for Sun Cluster software is instead performed by the Solaris implementation of Internet Protocol (IP) Network Multipathing. See What's New in Sun Cluster 3.1.

HAStorage

HAStorage might not be supported in a future release of Sun Cluster software. Near-equivalent functionality is supported by HAStoragePlus. Complete one of the following procedures to migrate from HAStorage to HAStoragePlus.

How to Upgrade from HAStorage to HAStoragePlus When Using Device Groups or Cluster File Systems

HAStorage might not be supported in a future release of Sun Cluster software. Equivalent functionality is supported by HAStoragePlus. To upgrade from HAStorage to HAStoragePlus when you use cluster file systems or device groups, complete the following steps.

The following example uses a simple HA-NFS resource active with HAStorage. The ServicePaths are the disk group nfsdg and the AffinityOn property is TRUE. Furthermore, the HA-NFS Service has Resource_Dependencies set to the HAStorage resource.

  1. Remove the dependencies the application resources has on HAStorage resource.


    # scrgadm -c -j nfsserver-rs -y Resource_Dependencies=""
    
  2. Disable the HAStorage resource.


    # scswitch -n -j nfs1storage-rs
    
  3. Remove the HAStorage resource from the application resource group.


    # scrgadm -r -j nfs1storage-rs
    
  4. Unregister the HAStorage resource type.


    # scrgadm -r -t SUNW.HAStorage
    
  5. Register the HAStoragePlus resource type.


    # scrgadm -a -t SUNW.HAStoragePlus
    
  6. Create the HAStoragePlus resource.

    To specify a file-system mount point, input the following text.


    # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \
    SUNW.HAStoragePlus -x FilesystemMountPoints=/global/nfsdata -x \
    AffinityOn=True
    

    To specify global device paths, input the following text.


    # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \
    SUNW.HAStoragePlus -x GlobalDevicePaths=nfsdg -x AffinityOn=True
    

    Note –

    Instead of using the ServicePaths property for HAStorage, you must use the GlobalDevicePaths or FilesystemMountPoints property for HAStoragePlus. The FilesystemMountPoints extension property must match the sequence specified in the /etc/vfstab file.


  7. Enable the HAStoragePlus resource.


    # scswitch -e -j nfs1-hastp-rs
    
  8. Set up the dependencies between the application server and HAStoragePlus.


    # scrgadm -c -j nfsserver-rs -y \
    Resource_Depencencies=nfs1=hastp-rs
    

How to Upgrade from HAStorage with Cluster File Systems to HAStoragePlus with Failover Filesystem

HAStorage might not be supported in a future release of Sun Cluster. Equivalent functionality is supported by HAStoragePlus. To upgrade from HAStorage to HAStoragePlus when using Failover Filesystem (FFS), complete the following steps.

The following example uses a simple NFS service active with HAStorage. The ServicePaths are the diskgroup nfsdg and the AffinityOn property is TRUE. Furthermore, the HA-NFS service has Resource_Dependencies set to the HAStorage resource.

  1. Remove the dependencies the application resource has on HAStorage.


    # scrgadm -c -j nfsserver-rs -y Resource_Dependencies=""'
  2. Disable the HAStorage resource.


    # scswitch -n -j nfs1storage-rs
    
  3. Remove the HAStorage resource from the application resource group.


    # scrgadm -r -j nfs1storage-rs
    
  4. Unregister the HAStorage resource type.


    # scrgadm -r -t SUNW.HAStorage
    
  5. Modify the /etc/vfstab file to remove the global flag and change mount at bootto no. This should be done on all nodes which are potential primaries for the resource group.

  6. Register the HAStoragePlus resource type.


    # scrgadm -a -t SUNW.HAStoragePlus
    
  7. Create the HAStoragePlus resource.

    To specify a file-system mount point, input the following text.


    # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \
    SUNW.HAStoragePlus -x FilesystemMountPoints=/global/nfsdata -x \
    AffinityOn=True
    

    To specify global device paths, input the following text.


    # scrgadm -a -j nfs1-hastp-rs -g nfs1-rg -t \
    SUNW.HAStoragePlus -x GlobalDevicePaths=nfsdg -x AffinityOn=True
    

    Note –

    Instead of using the ServicePaths property for HAStorage, you must use the GlobalDevicePaths or FilesystemMountPoints property for HAStoragePlus. The FilesystemMountPoints extension property must match the sequence specified in the /etc/vfstab file.


  8. Switch the application resource group offline.


    # scswitch -F -g nfs1-rg
    
  9. Disable the application resource.


    # scswitch -n -j nfsserver-rs
    
  10. Unmount the CFS file systems.

  11. Enable the HAStoragePlus resource.


    # scswitch -e -j nfs1-hastp-rs
    
  12. Bring the application resource group online on a given host.


    # scswitch -z -g nfs1-rg -h hostname
    
  13. Set up the dependencies between the application resource and HAStoragePlus.


    # scrgadm -c -j nfsserver-rs -y \
    Resource_Depencencies=nfs1=hastp-rs
    
  14. Enable the application resource.


    # scswitch -e -j nfs1-hastp-rs
