TIP:
If copy pairs have been defined using storage system operation management software such as Remote
Web Console, there is no configuration definition file (because there are copy pairs that are not
managed by pair management servers). In this case, you should execute the Device Manager refresh
function from Replication Manager. This will allow the pair information to be acquired from the
refreshed databases.
Performance-related information, copy progress, and the copy pair state for the secondary volume
cannot be acquired. For details on the Device Manager refresh function, see the HP P9000 Command
View Advanced Edition Suite Software Help or HP P9000 Command View Advanced Edition Suite
Software CLI Reference Guide. To view the flow of data in open systems, see “
Refreshing copy pair
statuses data flow (open systems) ” on page 259.
In mainframe systems, the copy pair statuses are acquired from the instances of HP StorageWorks
P9000 for Business Continuity Manager Software or P9000 mainframe agent registered as information
sources. To view the flow of data in mainframe systems, see “
Refreshing copy pair statuses data flow
(mainframe systems) ” on page 259.
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 260.
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.
Guideline for determining the interval for refreshing copy pair statuses
Guideline interval
Number of copy pairs on pair management
server or information source
3 minutes 0 to 1,000
5 minutes 1,001 to 2,000
10 minutes 2,001 to 3,000
15 minutes 3,001 to 5,000
