HP 3PAR InForm OS 3.1.1 Command Line Interface Reference

NOTES
• There is no default resynchronization period. For groups whose mode is asynchronous periodic,
you must specify a resynchronization period using setrcopygroup period
<period_value> or resynchronizations does not automatically take place.
• The minimum interval for periodic resynchronizations is five minutes.
• Use the -nosnap option when the primary server has failed or where the disks are ruined
or in an unknown state. For example, an uncontrolled shutdown can result in loss of data. If
you suspect that the primary volumes are not in a known good state, you should use this option
to force a FULL RESYNC when the primary system is restored.
• The -nosnap option can be used when making a secondary group take over as the primary
after a disaster takes down the primary (setrcopygroup failover -nosnap...). This
option indicates that no incremental resynchronization of the primary group is possible while
the primary system is coming back online. Without this option, a snapshot is taken when the
secondary server takes over as the primary. That snapshot is used to do an INCREMENTAL
synchronization of the primary after it is restored. This assumes that there was no loss of data
in the primary volumes when the primary server went down.
