Automatically restarting volume groups – HP 3PAR Operating System Software User Manual

Automatically Restarting Volume Groups
By default, remote-copy volume groups do not restart automatically.
•
To allow automatic restarts after all links between a remote-copy pair fail and are re-established,
set the volume groups to the auto_recover policy by using either of the following commands:
# setrcopygroup pol auto_recover
or:
# setrcopygroup pol auto_recover -pat
where
The auto_recover policy ensures that, if the volume groups stop as a result of total link
failure, they automatically restart when one of the links comes back up.
If the volume groups stop for any other reason (for example, I/O errors occur and the system
stops the volume groups), you must use the startrcopygroup command to manually restart
the volume groups.
•
To return the volume groups to the default policy and prevent volume groups from automatically
restarting, set the volume groups to the no_auto_recover policy by using either of the
following commands:
# setrcopygroup pol no_auto_recover
or:
# setrcopygroup pol no_auto_recover -pat
where
If volume groups stop for any kind of failure when the no_auto_recover policy has been set,
you must use the startrcopygroup command to manually restart the volume groups.
Generating Alerts for Slow Resynchronization of Asynchronous Periodic Volume
Groups
By default, HP 3PAR Remote Copy generates an alert if asynchronous periodic volume groups do
not complete resynchronization within the synchronization period specified by the setrcopygroup
period
command.
•
To prevent HP 3PAR Remote Copy from sending alerts when resynchronizations of asynchronous
periodic volume groups do not complete within the specified synchronization period, set the
volume groups to the no_over_per_alert policy by issuing either of the following
commands:
# setrcopygroup pol no_over_per_alert
or:
# setrcopygroup pol no_over_per_alert -pat
