How to Replicate the Volume Manager Configuration Information From the Primary Cluster

Before You Begin

If you are using storage-based replication, do not configure a replicated volume as a quorum device. The Sun Cluster Geographic Edition software does not support Hitachi TrueCopy S-VOL and Command Device as a Sun Cluster quorum device. See Using Storage-Based Data Replication in Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS for more information.

Start replication for the devgroup1 device group.

phys-paris-1# paircreate -g devgroup1 -vl -f async

phys-paris-1# pairdisplay -g devgroup1
Group PairVol(L/R) (Port#,TID,LU),Seq#,LDEV#,P/S,Status,Fence,Seq#,P-LDEV# M 
devgroup1 pair1(L) (CL1-A , 0, 1) 54321   1..P-VOL COPY ASYNC ,12345 609   -
devgroup1 pair1(R) (CL1-C , 0, 20)12345 609..S-VOL COPY ASYNC ,-----   1   -
devgroup1 pair2(L) (CL1-A , 0, 2) 54321   2..P-VOL COPY ASYNC ,12345 610   -
devgroup1 pair2(R) (CL1-C , 0, 21)12345 610..S-VOL COPY ASYNC ,-----   2   -

Wait for the state of the pair to become PAIR on the secondary cluster.

phys-newyork-1# pairdisplay -g devgroup1
Group PairVol(L/R) (Port#,TID,LU),Seq#,LDEV#,P/S,Status,Fence,Seq#,P-LDEV# M
devgroup1 pair1(L) (CL1-C , 0, 20)12345 609..S-VOL PAIR ASYNC,-----, 1     - 
devgroup1 pair1(R) (CL1-A , 0, 1) 54321   1..P-VOL PAIR ASYNC,12345, 609   - 
devgroup1 pair2(L) (CL1-C , 0, 21)12345 610..S-VOL PAIR ASYNC,-----, 2     - 
devgroup1 pair2(R) (CL1-A , 0, 2)54321    2..P-VOL PAIR ASYNC,12345, 610   -

Split the pair by using the pairsplit command and confirm that the secondary volumes on cluster-newyork are writable by using the -rw option.

phys-newyork-1# pairsplit -g devgroup1 -rw 
phys-newyork-1# pairdisplay -g devgroup1
Group PairVol(L/R) (Port#,TID,LU),Seq#,LDEV#,P/S,Status,Fence,Seq#,P-LDEV# M 
devgroup1 pair1(L) (CL1-C , 0, 20)12345 609..S-VOL SSUS ASYNC, -----  1    - 
devgroup1 pair1(R) (CL1-A , 0, 1) 54321   1..P-VOL PSUS ASYNC,12345  609   W 
devgroup1 pair2(L) (CL1-C , 0,21) 12345 610..S-VOL SSUS ASYNC,-----   2    - 
devgroup1 pair2(R) (CL1-A , 0, 2) 54321   2..P-VOL PSUS ASYNC,12345  610   W

Import the VERITAS Volume Manager disk group, oradg1.
phys-newyork-1# vxdg -C import oradg1

Verify that the VERITAS Volume Manager disk group was successfully imported.
phys-newyork-1# vxdg list

Enable the VERITAS Volume Manager volume.

phys-newyork-1# /usr/sbin/vxrecover -g oradg1 -s -b

Verify that the VERITAS Volume Manager volumes are recognized and enabled.
phys-newyork-1# vxprint

phys-newyork-1# scconf -a -D type=vxvm, name=oradg1, \
nodelist=phys-newyork-1:phys-newyork-2

Synchronize the volume manager information with the Sun Cluster device group and verify the output.
phys-newyork-1# scconf -c -D name=oradg1,sync phys-newyork-1# scstat -D

Add an entry to the /etc/vfstab file on phys-newyork-1.

phys-newyork-1# /dev/vx/dsk/oradg1/vol1 /dev/vx/rdsk/oradg1/vol1 \
/mounts/sample ufs 2 no logging

Create a mount directory on phys-newyork-1.
phys-newyork-1# mkdir -p /mounts/sample

Create an application resource group, apprg1, by using the scrgadm command.
phys-newyork-1# scrgadm -a -g apprg1

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=oradg1 \

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

Unmount the file system.
phys-newyork-1# umount /mounts/sample

Take the Sun Cluster device group offline.
phys-newyork-1# scswitch -F -D oradg1

Verify that the VERITAS Volume Manager disk group was deported.
phys-newyork-1# vxdg list

Reestablish the Hitachi TrueCopy pair.

phys-newyork-1# pairresync -g devgroup1 
phys-newyork-1# pairdisplay -g devgroup1 
Group PairVol(L/R) (Port#,TID,LU),Seq#,LDEV#,P/S,Status,Fence,Seq#,P-LDEV# M 
devgroup1 pair1(L) (CL1-C , 0, 20)12345 609..S-VOL PAIR ASYNC,-----   1    - 
devgroup1 pair1(R) (CL1-A , 0, 1) 54321   1..P-VOL PAIR ASYNC,12345  609   W 
devgroup1 pair2(L) (CL1-C , 0,21) 12345 610..S-VOL PAIR ASYNC,-----   2    - 
devgroup1 pair2(R) (CL1-A , 0, 2) 54321   2..P-VOL PAIR ASYNC,12345  610   W

Initial configuration on the secondary cluster is now complete.
