How to Create a Copy of the Volume Manager Configuration

This task copies the volume manager configuration from the primary cluster, cluster-paris, to LUNs of the secondary cluster, cluster-newyork, by using the VERITAS Volume Manager commands vxdiskadm and vxassist command.

The device group, devgroup1, must be in the Split state throughout this procedure.

1. Confirm that the pair is in the Split state.

   phys-newyork-1# symrdf -g devgroup1 query Source (R1) View Target (R2) View MODES -------------------------------- ------------------------ ----- ------------ ST LI ST Standard A N A Logical T R1 Inv R2 Inv K T R1 Inv R2 Inv RDF Pair Device Dev E Tracks Tracks S Dev E Tracks Tracks MDA STATE -------------------------------- -- ------------------------ ----- ------------ DEV001 00EC RW 0 0 NR 00EC RW 0 0 S.. Split DEV002 00ED RW 0 0 NR 00ED RW 0 0 S.. Split

2. Import the VERITAS Volume Manager disk group.

   phys-newyork-1# vxdg -C import dg1

3. Verify that the VERITAS Volume Manager disk group was successfully imported.

   phys-newyork-1# vxdg list

4. Enable the VERITAS Volume Manager volume.

   phys-newyork-1# /usr/sbin/vxrecover -g dg1 -s -b

5. Verify that the VERITAS Volume Manager volumes are recognized and enabled.

   phys-newyork-1# vxprint

6. Register the VERITAS Volume Manager disk group, dg1, in Sun Cluster software.

   phys-newyork-1# scconf -a -D type=vxvm, name=dg1, \ nodelist=phys-newyork-1:phys-newyork-2

7. Create a VERITAS Volume Manager volume.

8. Synchronize the VERITAS Volume Manager information with the Sun Cluster device group and verify the output.

   phys-newyork-1# scconf -c -D name=dg1, sync phys-newyork-1# scstat -D

9. Create a mount directory on phys-newyork-1.

   phys-newyork-1# mkdir -p /mounts/sample

10. Create an application resource group, apprg1 by using the scrgadm command.

    phys-newyork-1# scrgadm -a -g apprg1

11. Create the HAStoragePlus resource in apprg1.

    phys-newyork-1# scrgadm -a -j rs-hasp -g apprg1 -t SUNW.HAStoragePlus \ -x FilesystemMountPoints=/mounts/sample -x AffinityOn=TRUE \ -x GlobalDevicePaths=dg1

12. If necessary, confirm that the application resource group is correctly configured by bringing it online and taking it offline again.

    phys-newyork-1# scswitch -z -g apprg1 -h phys-newyork-1 phs-newyork-1# scswitch -F -g apprg1

13. Unmount the file system.

    phys-newyork-1# umount /mounts/sample

14. Take the Sun Cluster device group offline.

    phys-newyork-1# scswitch -F -D dg1

15. Verify that the VERITAS Volume Manager disk group was deported.

    phys-newyork-1# vxdg list
