Building Disaster Recovery Serviceguard Solutions Using Continentalclusters A.08.00

Creating VxVM Disk Groups
Run the following procedure to create VxVM Disk Groups
1. Initialize disks to be used with VxVM by running the vxdisksetup command only on the
primary system.
# /etc/vx/bin/vxdisksetup -i c5t0d0
2. Create the disk group to be used with the vxdg command only on the primary system.
# vxdg init logdata c5t0d0
3. Verify the configuration.
# vxdg list
4. Use the vxassist command to create the volume.
# vxassist -g logdata make logfile 2048m
5. Verify the configuration.
# vxprint -g logdata
6. Make the filesystem.
# newfs -F vxfs /dev/vx/rdsk/logdata/logfile
7. Create a directory to mount the volume group.
# mkdir /logs
8. Mount the disk group.
# mount /dev/vx/dsk/logdata/logfile /logs
9. Check if file system exits, then unmount the file system.
# umount /logs
Installing and Configuring an application in the primary site
Install the application at the primary site in a non replicated disk and configure it to run such that
the data is stored in the replicated disks. The installed application and its resources such as volume
groups , file system mount points must be configured as a Serviceguard package as explained in
the section “Configuring the Continentalclusters primary and recovery packages” (page 15).
Installing and configuring a redundant copy of the application in the
recovery site
Install the application at the secondary site and configure it to use the same replicated disks as in
the previous step. Then configure the application and its resources as a Serviceguard package.
Configuring the Continentalclusters primary and recovery packages
The packages can be created using any modules supported by HP Serviceguard.
For example, for Oracle application, the Serviceguard Oracle toolkit can be used to create the
primary and recovery packages in Continentalclusters.
Continentalclusters supports the following pre-integrated physical replication solutions:
• Continuous Access P9000 and XP
• Continuous Access EVA
• EMC Symmetrix Remote Data Facility
• 3PAR Remote Copy
