Serviceguard Configuration for Oracle RAC
Planning Database Storage
Chapter 234
Volume Planning with CVM
Storage capacity for the Oracle database must be provided in the form of
volumes located in shared disk groups. The Oracle software requires at
least two log files (an one undo tablespace for Oracle9) for each Oracle
instance, several Oracle control files and data files for the database itself.
For all these files, Serviceguard Extension for RAC uses HP-UX raw
volumes, which are located in disk groups that are shared between the
nodes in the cluster. High availability is achieved by using high
availability disk arrays in RAID nodes. The logical units of storage on
the arrays are accessed from each node through multiple physical
volume links via DMP (Dynamic Multi-pathing), which provides
redundant paths to each unit of storage.
Fill out the VERITAS Volume worksheet to provide volume names for
volumes that you will create using the VERITAS utilities. The Oracle
DBA and the HP-UX system administrator should prepare this
worksheet together. Create entries for shared volumes only. For each
volume, enter the full pathname of the raw volume device file. Be sure to
include the desired size in MB. Following is a sample worksheet filled
out. Refer to Appendix A, “Blank Planning Worksheets,” for samples of
blank worksheets. Make as many copies as you need. Fill out the
worksheet and keep it for future reference.
