HP P9000 Replication Manager Software 7.2.0-01 Release Notes (TB584-96048, February 2012)

Conditions
• The task is a scheduled task that has already been executed at least once.
• The previous time when the task was executed, and the next time the task should be executed all
meet the following conditions:
◦ hh2 > hh1
◦ MM > mm2
hh1:mm1 — The previous time when the task was executed (start time)
hh2:mm2 — The previous time when the task was executed (end time)
HH:MM — The next time the task should be executed (start time)
NOTE: The delay of the task execution is hh2 – hh1 (hour).
For example, in the case of the following task, the next execution should start at 6:30, but the next
execution actually starts at 7:30.
• The previous time when the task was executed (start time): 5:30
• The previous time when the task was executed (end time): 6:20
• The next time the task should be executed (start time): 6:30
• The selected execution interval for the task: 1 hour
• The actual delay between the end of one task occurrence and the start of the next task occurrence:
1 hour 10 minutes (6:30 – 6:20 = 10 minutes, plus 6:30 – 5:30 = 1 hour)
• The actual start time of the next scheduled task: 7:30 (not 6:30)
