Creating a Storage Infrastructure with CFS
In addition to configuring the cluster, you create the appropriate logical volume infrastructure
to provide access to data from different nodes. This is done with Logical Volume Manager (LVM),
Veritas Volume Manager (VxVM), or Veritas Cluster Volume Manager (CVM). You can also use
a mixture of volume types, depending on your needs. LVM and VxVM configuration are done
before cluster configuration, and CVM configuration is done after cluster configuration.
This section has information about configuring a cluster that uses the Veritas cluster file system
(CFS) with Veritas Cluster Volume Manager (CVM) 4.1 or later. The next section (“Creating a
Storage Infrastructure with CVM” (page 97)) has information about configuring the Veritas
Cluster Volume Manager (CVM) with other filesystems, not CFS.
For more information refer to your version of the Serviceguard Extension for RAC Release Notes
and HP Serviceguard Storage Management Suite Release Notes located at http://docs.hp.com
-> High Availability.
Creating a SGeRAC Cluster with CFS for Oracle 9i
The following software needs to be pre-installed in order to use this configuration:
If you are installing CFS 4.1 or 5.0 with either the Storage Management Suite (SMS) bundle or
Mission Critical Operating Environment (MCOE), High Availability Operating Environment
(HAOE), Data Center Operating Environment (DCOE) use the appropriate product number as
described below:
• SGeRAC and CFS 5.0 are included with the HP Serviceguard Storage Management Suite
(SMS) bundle or MCOE/HAOE/DCOE.
With CFS, the database software and database files (control, redo, data files), and archive logs
may reside on a cluster file system, which is visible by all nodes.
In the following example, both the Oracle software and datafiles reside on CFS. There is a single
Oracle home. The following three CFS file systems are created for Oracle home, Oracle datafiles,
and SRVM data:
/cfs/mnt1 – for Oracle Base and Home
/cfs/mnt2 – for Oracle datafiles
/cfs/cfssrvm - for SRVM data
Initializing the Veritas Volume Manager
Use the following steps to create a two node SGeRAC cluster with CFS and Oracle:
1. Initialize the Veritas Volume Manager
If not already done, install the VxVM license key on all nodes. Use the following command:
# vxinstall
For each question raised when running the vxinstall command to install the VxVM
licence key, respond with “n”.
IMPORTANT: Creating a rootdg disk group is only necessary the first time you use the
Volume Manager. CVM 4.1 or later does not require a rootdg.
2. Create the Cluster file:
# cd /etc/cmcluster
# cmquerycl -C clm.asc -n ever3a -n ever3b
Edit Cluster file
