Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

Complete the following procedure on the CVM cluster master node in the primary sub-cluster to
set up the CVM disk group volumes:
1. Initalize the source disks of the replication pair:
# /etc/vx/bin/vxdisksetup -i <replicated_disk_1>
# /etc/vx/bin/vxdisksetup -i <replicated_disk_2>
2. Create a disk group for the complex workload data:
# vxdg –s init <cvm_dg_name> <replicated_disk_1> <replicated_disk_2>
3. Activate the CVM disk group in the primary sub-cluster:
# vxdg -g <cvm_dg_name> set activation=sw
4. Create a volume from the disk group:
# vxassist -g <cvm_dg_name> make <cvm_dg_vol_name> 4500m
5. Skip this step if CFS is not required and SG SMS CVM will be used as raw volumes.
Create a filesystem:
# newfs -F vxfs /dev/vx/rdsk/<cvm_dg_name>/<cvm_dg_vol_name>
6. Create a package configuration file:
# cmmakepkg -m sg/cfs_all /etc/cmcluster/cfspkg1.ascii
7. Edit the following package parameters in the cfspkg1.ascii package configuration file:
node_name <node1>
node_name <node2>
package_name <siteA_cfs_pkg_name>
cvm_disk_group <cvm_dg_name>
cvm_activation_mode "node1=sw node2=sw"
cfs_mount_point <cvm_mount_point>
cfs_volume <cvm_dg_name>/<cvm_dg_vol_name>
cfs_mount_options "node1=cluster node2=cluster"
cfs_primary_policy ""
Where node1 and node2 are the nodes at the primary sub-cluster.
Do not configure any mount specific attributes like cfs_mount_point, cfs_mount_options if SG
SMS CVM is configured as raw volumes.
8. Check the package configuration file:
# cmcheckconf -P cfspkg1.ascii
9. Apply the package configuration file:
# cmapplyconf -P cfspkg1.ascii
10. Run the package:
# cmrunpkg <siteA_cfs_pkg_name>
For instructions on how to migrate legacy CFS package to modular CFS package, see “Migrating
Complex Workloads Using Legacy SG SMS CVM/CFS Packages to Modular SG SMS CVM/CFS
Packages with Minimal Downtime” (page 399).
Configuring the Storage Device using CFS in a Legacy Style Package
NOTE: HP recommends you to use the modular style of packaging.
Complete the following procedure to configure a storage device using CFS in a legacy style
package:
1. Initialize the source disks of the replication pair.
# /etc/vx/bin/vxdisksetup -i <replicated_disk_1>
# /etc/vx/bin/vxdisksetup -i <replicated_disk_2>
2. Create a disk group for the complex workload data.
# vxdg –s init <cvm_dg_name> <replicated_disk_1>\
