Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA P6000 for Linux B.12.00.00

Table 4 Temp.config file Attributes
DescriptionAttributes
This is the package directory for this Metrocluster modular
package. The Metrocluster Environment file is generated for this
dts_pkg_dir
package in this directory. This value must be unique for all
packages.
This is a parameter used to define a policy for starting an
application. It can be set to Availability_Preferred or
Data_Currency_Preferred policy.
DT_APPLICATION_STARTUP_POLICY
This is the name of the DR group used by the package.DR_GROUP_NAME
This is the World Wide Name of the HP P6000/EVA storage
system that resides in Data Center 1.
DC1_STORAGE_WORLD_WIDE_NAME
This is a list of management servers that reside in Data Center 1.DC1_SMIS_LIST
This is a parameter used to specify a list of clustered nodes that
reside in Data Center 1.
DC1_HOST_LIST
This is the World Wide Name of the P6000/EVA storage system
that resides in Data Center 2.
DC2_STORAGE_WORLD_WIDE_NAME
This is a list of management servers that reside in Data Center 2.DC2_SMIS_LIST
This is a parameter used to specify a list of clustered nodes that
reside in Data Center 2.
DC2_HOST_LIST
NOTE: The host name specified in DC1/DC2 parameter must match the output of the
hostname command. If hostname command displays a fully qualified name, then you must
specify the fully qualified name in DC1/DC2 host parameter list.
For Example:
# hostname
host1.domain1.com
If hostname command displays only host name, then you must specify the host name in
DC1/DC2 parameter list.
For Example:
# hostname
host1
There are additional Metrocluster parameters available in the package configuration file. HP
recommends that you retain the default values of these variables unless there is a specific
business requirement to change them. For more information on the Metrocluster parameters,
see Appendix B (page 39).
For the failover_policy parameter, Metrocluster failover packages can be configured to
use any of the Serviceguard defined failover policies. The site_preferred and
site_preferred_manual failover policies are introduced in Serviceguard specifically for
Metrocluster configurations.
The site_preferred value implies that when a Metrocluster package needs to fail over, it
fails over to a node in the same site as the node it last ran. If there is no other configured node
available within the same site, the package fails over to a node on another site.
The site_preferred_manual failover policy provides automatic failover of packages
within a site and manual failover across sites.
