HP XP P9000 Replication Manager Software 7.6.1-00 User Guide

For a local instance of Device Manager, this synchonization is always performed as needed (so there
is no need for manual or scheduled refresh operations). The following events trigger synchronization
of the Replication Manager and Device Manager databases:
• Storage system updates that change the configuration
• Adding or deleting storage systems
• Adding or deleting hosts
• Adding or deleting copy pairs using the CLI
For storage controlled by a remote instance of Device Manager, a manual refresh can be performed
at any time as described in “Refreshing configuration information manually for each information
source” on page 283, or it can be refreshed automatically.
Refresh operations for remote instances of Device Manager
The automatic refresh of configuration information for remote instances of Device Manager is controlled
by to two types of settings:
• Automatic updating in conjunction with storage systems refresh operations
• Periodic updating based on a specified refresh interval
Replication Manager allows you to use either one or both of the above settings to automatically refresh
configuration information associated with remote instances of Device Manager. In the initial settings
of Replication Manager, the automatic update setting is enabled and the periodic update setting is
disabled.
TIP:
The configuration might be updated often if both settings are enabled. Therefore HP recommends that
if you want to enable the periodic update setting, you disable the automatic update setting.
Automatic refreshing
When automatic refreshing of configuration information is enabled, Replication Manager regularly
checks whether remote Device Manager servers registered as information sources have refreshed
their storage systems configurations, then synchronizes the Device Manager and Replication Manager
databases.
You can enable or disable this automatic refresh by setting the
base.repositry.synchronize.polling property in the base.properties file on the
management server. When this property is set to true, these two parameters go into effect:
• base.repositry.synchronize.interval: the monitoring interval at which regular checks
for storage refresh are performed.
• base.repositry.synchrocheck.interval: the interval at which a message is displayed
if configuration information is not synchronized.
For details on these properties, see the HP P9000 Replication Manager Software Configuration Guide.
