This publication provides information about configuring the IRIS FailSafe product to run with the Data Migration Facility (DMF).
|Note: IRIS DMF FailSafe does not support a dual-active configuration.|
This chapter provides information about the components that are added to the base IRIS FailSafe product by the IRIS FailSafe DMF option. It assumes you are familiar with the basic components of IRIS FailSafe described in Chapter 1 of the IRIS FailSafe Administrator's Guide. This chapter also lists the steps you must take to add DMF components to the highly available services that are failed over on an IRIS FailSafe cluster.
The IRIS Failsafe DMF option adds DMF monitoring and fail over scripts to the IRIS base software. The monitoring script monitors the availability and status of the DMF daemon. If the script detects that the daemon is not running or responding to requests, the script takes the following actions:
Writes an error message to the monitoring script's log file (/var/ha/logs/ha_dmf_lon.$HOST.log ). For example:
Tue Sep 22 00:01:27 CDT 1998 DMF has STOPPED , check DMF logfiles
Sends an error message to the system console indicating DMF has stopped. For example:
Tue Sep 22 00:01:28 DMF STOPPED , check DMF logfiles
Sends a mail message with error information to the mail address defined by the mail-dest-addr field. For example:
Tue Sep 22 00:01:26 DMF STOPPED , check DMF logfiles
To configure an IRIS FailSafe cluster for fail over of DMF, complete the following steps:
Install, configure, and test the version 1.2 base IRIS FailSafe software as described in the IRIS FailSafe Administrator's Guide.
Choose how to configure the DMF software, databases, and DMF file systems, as described in “DMF File System Configuration” in Chapter 2.
Install DMF on each node in the cluster.
Set up DMF configuration files as described in “DMF Configuration Files” in Chapter 2.
Set up tape configuration files if DMF is running the tape media-specific process (MSP), as described in “Tape Configuration” in Chapter 2.
Install the FailSafe DMF software.
Add DMF information to the /var/ha/ha.conf configuration file, as described in “Adding DMF Information to the FailSafe Configuration File” in Chapter 2.
Install the new configuration files on each node, as described in Procedure 2-1.
Test DMF fail over as described in “Testing DMF Fail Over” in Chapter 2.
