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

B Package attributes for Metrocluster with Continuous Access
EVA P6000 for Linux
This appendix lists all Package Attributes for this product. HP recommends that you use the default
settings for most of these variables, so exercise caution when modifying them:
CLUSTER_TYPE This parameter identifies the type of disaster recovery
services cluster: Metrocluster or Continentalclusters. You
must set this to “metro” if this is a Metrocluster environment
and “continental” if this is a Continentalclusters environment.
A type of “metro” is supported only when the HP
Metrocluster product is installed. A type of “continental” is
supported only when the HP Continentalclusters and
Metrocluster software are installed.
PKGDIR If the package is a legacy package, this variable contains
the full path name of the package directory. If the package
is a modular package, this variable contains the full path
name of the directory where the Metrocluster caeva
environment file is located.
DT_APPLICATION_STARTUP_POLICY This parameter defines the preferred policy to start the
application with respect to the state of the data in the local
volumes. It should be set to one of the following two policies:
Availability_Preferred: The user chooses this policy
if he prefers application availability. Metrocluster software
allows the application to start if the data is consistent even
if the data is not current.
Data_Currency_Preferred:The user chooses this policy
if he prefers the application to start on consistent and current
data. Metrocluster software allows the application to operate
only on current data. This policy only focuses on the state
of the local data (with respect to the application) being
consistent and current.
A package can be forced to start on a node by creating the
FORCEFLAG in the package directory.
WAIT_TIME (0 or greater than 0 [in minutes])
This parameter defines the timeout, in minutes, to wait for
completion of the data merging or copying for the DR group
before startup of the package on destination volume.
If WAIT_TIME is greater than zero, and if the state of DR
group is “merging in progress” or “copying in progress”,
Metrocluster software waits until WAIT_TIME value for the
merging or copying is complete. If WAIT_TIME expires and
merging or copying is still in progress, the package fails to
start with an error.
If WAIT_TIME is 0 (default value), and if the state of DR
group is “merging in progress” or “copying in progress”
state, Metrocluster software will not wait and will return an
exit 1 code to Serviceguard package manager. The package
fails to start with an error.
DR_GROUP_NAME The name of the DR group used by this package. The DR
group name is defined when the DR group is created.
