Sun Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility

ProcedureHow to Replicate the VERITAS Volume Manager Configuration Information From the Primary Cluster

  1. Start replication for the devgroup1 device group.


    phys-paris-1# symrdf -g devgroup1 -noprompt establish
    
    An RDF 'Incremental Establish' operation execution is in progress for device group 
    'devgroup1'. Please wait... 
    Write Disable device(s) on RA at target (R2)..............Done. 
    Suspend RDF link(s).......................................Done.
    Mark target (R2) devices to refresh from source (R1)......Started. 
    Device: 054 ............................................. Marked. 
    Mark target (R2) devices to refresh from source (R1)......Done. 
    Suspend RDF link(s).......................................Done. 
    Merge device track tables between source and target.......Started. 
    Device: 09C ............................................. Merged. 
    Merge device track tables between source and target.......Done. 
    Resume RDF link(s)........................................Done. 
    
    The RDF 'Incremental Establish' operation successfully initiated for device group 
    'devgroup1'. 
  2. Confirm that the state of the EMC Symmetrix Remote Data Facility pair is synchronized.


    phys-newyork-1# symrdf -g devgroup1 verify
    
    All devices in the RDF group 'devgroup1' are in the 'Synchronized' state.
  3. Split the pair by using the symrdf split command.


    phys-paris-1# symrdf -g devgroup1 -noprompt split
    
    An RDF 'Split' operation execution is in progress for device group 'devgroup1'. 
    Please wait... 
    
    Suspend RDF link(s).......................................Done. 
    Read/Write Enable device(s) on RA at target (R2)..........Done. 
    The RDF 'Split' operation device group 'devgroup1'. 
  4. Enable all the volumes to be scanned.


    phys-newyork-1# vxdctl enable
    
  5. Import the VERITAS Volume Manager disk group, dg1.


    phys-newyork-1# vxdg -C import dg1
    
  6. Verify that the VERITAS Volume Manager disk group was successfully imported.


    phys-newyork-1# vxdg list
    
  7. Enable the VERITAS Volume Manager volume.


    phys-newyork-1# /usr/sbin/vxrecover -g dg1 -s -b
    
  8. Verify that the VERITAS Volume Manager volumes are recognized and enabled.


    phys-newyork-1# vxprint
    
  9. Create the VERITAS Volume Manager disk group, dg1, in Sun Cluster software.


    phys-newyork-1# cldevicegroup create -n phys-newyork-1,phys-newyork-2 \
    -t vxvm dg1
    
  10. Add an entry to the /etc/vfstab file on phys-newyork-1.


    /dev/vx/dsk/dg1/vol1 /dev/vx/rdsk/dg1/vol1 /mounts/sample ufs 2 no logging
    
  11. Create a mount directory on newyork.


    phys-newyork-1# mkdir -p /mounts/sample
    phys-newyork-2# mkdir -p /mounts/sample
    
  12. Create an application resource group, apprg1, by using the clresourcegroup command.


    phys-newyork-1# clresourcegroup create apprg1
    
  13. Create the HAStoragePlus resource in apprg1.


    phys-newyork-1# clresource create -g apprg1 -t SUNW.HAStoragePlus \
    -p FilesystemMountPoints=/mounts/sample -p AffinityOn=TRUE \
    -p GlobalDevicePaths=dg1 rs-hasp
    

    This HAStoragePlus resource is required for Sun Cluster Geographic Edition systems because the software relies on the resource to bring the device groups and file systems online when the protection group starts on the primary cluster.

  14. Confirm that the application resource group is correctly configured by bringing it online and taking it offline again.


    phys-newyork-1# clresourcegroup online -emM apprg1
    phs-newyork-1# clresourcegroup offline apprg1
    
  15. Unmount the file system.


    phys-newyork-1# umount /mounts/sample
    
  16. Take the Sun Cluster device group offline.


    phys-newyork-1# cldevicegroup offline dg1
    
  17. Verify that the VERITAS Volume Manager disk group was deported.


    phys-newyork-1# vxdg list
    
  18. Reestablish the EMC Symmetrix Remote Data Facility pair.


    phys-newyork-1# symrdf -g devgroup1 -noprompt establish
    

    Initial configuration on the secondary cluster is now complete.
