HP XP Array Manager Software - Manual (Page 256)

Copy pair statuses can be refreshed manually (from a subwindow) or automatically (at an interval
preset in the refresh settings). Normally, refreshing takes anywhere from a few to tens of minutes total.
However, if the Device Manager refresh function is used (because there are copy pairs not managed
by pair management servers in open systems), refreshing can require anywhere from a few to tens
of minutes for each storage system. If all copy pairs are managed by pair management servers,
disable the Device Manager refresh function. For details, see “
Disabling the Device Manager refresh
function ” on page 258.
When you determine the interval for refreshing copy pair statuses on open systems, use the number
of monitored copy pairs on each pair management server. For mainframe systems, use the number
of monitored copy pairs on each information source as a guideline. The following table provides
guidelines for determining the interval for refreshing copy pair statuses.
