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 242).
6.8 Creating a Disk Monitor Configuration
Serviceguard provides disk monitoring for the shared storage that is activated by packages in the
cluster. The monitor daemon on each node tracks the status of all the disks on that node that you
have configured for monitoring.
The configuration must be done separately for each node in the cluster, because each node monitors
only the group of disks that can be activated on that node, and that depends on which packages
are allowed to run on the node.
To set up monitoring, include a monitoring service in each package that uses disks you want to
track. Remember that service names must be unique across the cluster; you can use the package
name in combination with the string cmresserviced. The following shows an entry in the package
configuration file for pkg1:
service_name cmresserviced_pkg1
service_fail_fast_enabled yes
service_halt_timeout 300
service_cmd "cmresserviced /dev/sdd1 /dsv/sde1"
service_restart none
CAUTION: Because of a limitation in LVM, service_fail_fast_enabled must be set to
yes, forcing the package to fail over to another node if it loses its storage.
NOTE: The service_cmd entry must include the cmresserviced command.
It is also important to set service_restart to none.
