Using Serviceguard Extension for RAC, 6th Edition, April 2008

Adding Disk Groups to the Cluster Configuration
For CVM 4.x or later, if the multi-node package was configured for disk group activation,
the application package should be configured with package dependency to ensure the
CVM disk group is active.
For CVM 3.5 and CVM 4.x or later (without using multi-node package) after creating
units of CVM storage with VxVM commands, you need to specify the disk groups in
each package configuration ASCII file. Use one STORAGE_GROUP parameter for each
CVM disk group the package will use. You also need to identify the CVM disk groups,
file systems, logical volumes, and mount options in the package control script. (on
HP-UX releases that support them; see “About Veritas CFS and CVM from Symantec”
(page 25)).
For more detailed information on the package configuration process refer to the
Managing Serviceguard Fifteenth Edition user’s guide.
Prerequisites for Oracle 10g (Sample Installation)
The following sample steps prepare a SGeRAC cluster for Oracle 10g. Refer to the
Oracle documentation for Oracle installation details.
1. Create Inventory Groups on each Node
Create the Oracle Inventory group if one does not exist, create the OSDBA group,
and create the Operator Group (optional).
# groupadd oinstall
# groupadd dba
# groupadd oper
2. Create Oracle User on each Node
# useradd -u 203 -g oinstall -G dba,oper oracle
3. Change the Password on each Node
# passwd oracle
4. Create Symbolic Links
Required if Motif 2.1 Development Environment Package is not installed.
