Managing HP Serviceguard A.12.00.00 for Linux, June 2014

Oracle and NFS Toolkits Environment
For information about alert notification on Oracle and NFS toolskits environment, see the following
documents at http://www.hp.com/go/linux-serviceguard-docs:
• HP Serviceguard Toolkit for Oracle version A.05.01.10 on Linux User Guide
• HP Serviceguard Toolkit for NFS version A.03.03.10 on Linux User Guide
serviceguard-xdc Environment
By default, this parameter is commented and is present in the package configuration file for the
serviceguard-xdc packages.
The email_id parameter must be used to provide email addresses of the serviceguard-xdc alert
notification recipients. Each email_id parameter can have one of the following values:
• A complete email address
• An alias
• A distribution list
You can also include multiple recipients by repeating the email_id address.
The serviceguard-xdc package can send an alert email:
• when a mirror half of the MD device becomes inaccessible
• when raid_monitor service cannot add back a mirror half of the MD device after the mirror
half becomes accessible.
For example, consider the following scenario:
If the xdcpkg package is running on node1 and the MD device configured in xdcpkg package
is /dev/md0. /dev/hpdev/my_disk1 and /dev/hpdev/my_disk2 are the mirror halves of
the MD /dev/md0, and for some reason /dev/hpdev/my_disk2 becomes inaccessible. If the
email_id specified in the package configuration file is [e-mail]. The following email
notification is sent to [e-mail]:
Date: Tue, 9 Oct 2012 23:18:01 -0700
From: root <[e-mail]>
Message-Id: <[e-mail]>
To: [e-mail]
Subject: Serviceguard Alert: Package xdcpkg has lost access to my_disk2 of md0 on node1
Hi,
There seems to be an issue in the package xdcpkg in your Serviceguard cluster.
For more information, check the package and system logs of node1.hp.com.
Time of failure : Tue Oct 9 23:18:01 PDT 2012
Cluster Name : node1_cluster
Node name : node1.hp.com
Location of package log: /usr/local/cmcluster/run/log/xdcpkg.log
The mirror half /dev/hpdev/my_disk2 of MD device /dev/md0, which is configured in package xdcpkg, is not
accessible from node node1. Please rectify the issue.
Thanks.
6.7 Adding the Package to the Cluster
You can add the new package to the cluster while the cluster is running, subject to the value of
max_configured_packages in the cluster configuration file. See “Adding a Package to a
Running Cluster” (page 246).
6.8 How Control Scripts Manage VxVM Disk Groups
VxVM disk groups are outside the control of the Serviceguard cluster. The package control script
uses standard VxVM commands to import and deport these disk groups. (For more information on
importing and deporting disk groups, see the import and deport options in the vxdg man
page.)
