HP serviceguard t2808-90006 Editing the raid.conf File, To Edit the Xdcconfig File parameter

Configuring your Environment for Software RAID

Configuring the Package Control Script and RAID Configuration File

To Edit the XDC_CONFIG FILE parameter

In addition to modifying the DATA_REP variable, you must also set

XDC_CONFIG_FILE to specify the raid.conf file for this package. This file resides in the package directory.

For example: XDC_CONFIG_FILE="$SGCONF/oracle_pkg/raid.conf”

To Configure the RAID Monitoring Service

After you have edited the variables in the XDC configuration file

(XDC_CONFIG_FILE), you must set up RAID monitoring as a service within Serviceguard. Following is an example of how the file content must look:

SERVICE_NAME[0]="RAID_monitor"

SERVICE_CMD[0]="$SGSBIN/raid_monitor '${XDC_CONFIG_FILE}'"

SERVICE_RESTART[0]=""

Ensure that this service is also configured in the package configuration file as shown below:

SERVICE_NAME raid_monitor

SERVICE_FAIL_FAST_ENABLED YES

SERVICE_HALT_TIMEOUT 300

After editing the package control script, you must edit the raid.conf file to enable Software RAID.
