Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA A.05.01

9. Mount the cluster file system on the CFS sub-cluster.
# cfsmount /cfs/rac
10. Create a directory structure for the RAC database data files in the cluster file system. Set proper
permission and owners for the directory.
# chmod 775 /cfs/rac
# mkdir /cfs/rac/oradata
# chmod 775 /cfs/rac/oradata
# chown oracle:oinstall /cfs/rac/oradata
Setting up CFS file systems for RAC database flash recovery
This section describes how to create CFS file systems for RAC database flash recovery.
If you have SLVM, CVM, or CFS configured in your environment, see the following documents
available at http://www.hp.com/go/hpux-serviceguard-docs->HP Serviceguard Extension for
RAC:
• Architecture Considerations and Best Practices for Architecting an Oracle RAC Solution with
Serviceguard and SGeRAC
• Using Serviceguard Extension for RAC
The following procedure explains the method to configure the CFS file systems for flash recovery
for the example hrdb database.
To set up the CFS file systems on the CFS cluster master node:
1. Initialize the source disks of the replication pair.
# /etc/vx/bin/vxdisksetup -i c4t0d4
# /etc/vx/bin/vxdisksetup -i c4t0d5
2. Create a disk group using the above initialized disks.
# vxdg –s init flashdg c4t0d4 c4t0d5
3. Create Serviceguard Disk Group MNP package for the disk group.
# cfsdgadm add flashdg sfo_flash_dg all=sw SFO_1 SFO_2
4. Activate the disk group in the site CFS sub-cluster.
# cfsdgadm activate flashdg
5. Create a volume from the entire disk group.
# vxassist -g flashdg make flash_vol 4500m
6. Create a file system using the created volume.
# newfs -F vxfs /dev/vx/rdsk/flashdg/flash_vol
7. Create mount points for the RAC database flash logs and flash area.
# mkdir /cfs
# chmod 775 /cfs
# mkdir /cfs/flash
8. Create Mount Point MNP package for the cluster file system.
# cfsmntadm add flashdg flash_vol /cfs/flash sfo_flash_mp all=rw
SFO_1\
SFO_2
9. Mount the RAC database flash recovery file system in the site CFS sub-cluster.
# cfsmount /cfs/flash
10. Create directory structure in the cluster file system for the RAC database flash recovery area.
# chmod 775 /cfs/flash
