Configuring your Environment for Software RAID
Configuring the Package Control Script and RAID Configuration File
Chapter 3 77
# Specify the method of activation and deactivation for md.
# Leave the default (RAIDSTART="raidstart", "RAIDSTOP="raidstop") if you want
# md to be started and stopped with default methods.
RAIDSTART="raidstart -c ${RAIDTAB}"
RAIDSTOP="raidstop -c ${RAIDTAB}"
Creating and Editing the Package Control Scripts
After you install the XDC software, you need to create a package control
script and add references to the XDC software to enable Software RAID.
After you create the package control script you need to complete the
following tasks:
• Edit the value of the DATA_REP variable
• Edit the value of the XDC_CONFIG_FILE to point to the location where
the raid.conf file is placed
• Configure the RAID monitoring service
To Create a Package Control Script
The procedure to create a package control script for XDC software is
identical to the procedure that you follow to create other package control
scripts.
To create a package control script, run the following command:
# cmmakepkg –s <package file name>.sh
For example: # cmmakepkg –s oracle_pkg.sh
An empty template file for this package is created. You will need to edit
this package control script, in order to enable Software RAID in your
environment.
To Edit the DATA_REP Variable
The DATA_REP variable defines the nature of data replication that is
used. To enable Software RAID, set the value of this variable to MD. You
must set this value for every package that you need to enable Software
RAID. When you set this parameter to xdcmd, it enables remote data
replication through Software RAID.
For example: DATA_REP=”xdcmd”
