• Start Day – the day of the week on which the echo copy job begins. HP recommends that
copies are scheduled on a different day and/or time window from other backup activities.
• Start Time – the time at which the echo copy job begins. HP recommends that copies are
scheduled within a different time window from other backup activities.
• Window Duration – the number of hours available during which the echo copy job can take
place. If the migration does not take place during this window, the job is maintained in the
queue until the next start time.
For SAN destinations, HP recommends that you schedule mirror copies on a different day/time
window than backup activities. For LAN/WAN destinations, HP recommends that you allow
mirror copies to run 24 hours a day unless there is a need to restrict the use of LAN/WAN
bandwidth during certain periods of the day.

If the pool was successfully created, the Copy Pools screen displays, along with the message,
“The echo copy pool [echo copy pool name] was successfully created.”
If the pool was not created, the CREATE NEW ECHO COPY POOLS screen refreshes and provides
an error message at the bottom of the screen. Failure to create the pool most often occurs because
the slot numbers chosen are outside the available slot range. “The start slot is not in a free range
of slots” displays if only the start slot or both the start and end slots are out of range. “The end
slot is not in a free range of slots” displays if only the end slot is out of range.
