Managing Serviceguard Eighteenth Edition, September 2010
This command creates a 1024 MB volume named log_files in a disk group named
logdata. The volume can be referenced with the block device file /dev/vx/dsk/
logdata/log_files or the raw (character) device file /dev/vx/rdsk/logdata/
log_files.
Verify the configuration with the following command:
vxdg list
Now deport the disk groups:
vxdg deport <disk group name>
Adding Disk Groups to the Package Configuration
Next you need to specify the CVM disk groups for each package that uses them. You
do this in the package configuration file for modular packages and in the package
control script for legacy packages. Use one cvm_dg for each disk group the package
will use, and select the appropriate cvm_activation_cmd. Package configuration is
described in detail in Chapter 6 (Chapter 7 for legacy packages).
All packages (both legacy and modular) that use CVM disk groups also need to declare
a dependency on the SG-CFS-pkg in their package configuration file, specifying
dependency_condition as UP and dependency_location as same_node; for example:
dependency_name SG-CFS-pkg_dep
dependency_condition SG-CFS-pkg = UP
dependency_location same_node
Using DSAU during Configuration
You can use DSAU to centralize and simplify configuration and monitoring tasks. See
“What are the Distributed Systems Administration Utilities?” (page 34).
Managing the Running Cluster
This section describes some approaches to routine management of the cluster. Additional
tools and suggestions are found in Chapter 7, “Cluster and Package Maintenance.”
Checking Cluster Operation with Serviceguard Manager
You can check configuration and status information using Serviceguard Manager: from
the System Management Homepage (SMH), choose Tools-> Serviceguard
Manager.
