HP XP P9000 Command View Advanced Edition Software - Manual (Page 175)

Because associated tasks have an execution order, a task that must be executed prior to another task
is known as a prerequisite task. If an execution problem occurs, error messages are displayed indicating
when a prerequisite task has failed and the steps necessary to correct the problem.
TIP:
You need to re-create the task if all the following conditions are satisfied:
• The port number, host group, or pair management server WWN was changed after the task was
created.
• The task was created by the Pair Configuration or Change Pair Status Wizards, the task status is
Ready, and the execution type is Immediate or Schedule.

About task statuses
Tasks can be in one of the following execution statuses:
• Ready: Indicates that the task is waiting to execute.
NOTE:
If there are multiple tasks created by the Pair Configuration Wizard and they deal with same
resources, the tasks cannot be executed simultaneously. The tasks are executed in ascending order
of task ID. For this reason, if you specify immediate execution to multiple tasks or specify the same
execution time to multiple tasks, statuses of some tasks might be still Ready although the execution
time has passed.
• Executing: Indicates that the task is executing.
• Cancel: Indicates that the task was canceled.
• Failure: Indicates that the task failed. When you select Failure, an error window appears. Read
the message in the error window.
• Success: Indicates that the task was successful.
• Warning: Indicates that the system timed out while waiting for the task to finish processing, or in-
dicates that the cancellation of an Executing task has completed. When you select Warning, an
error window appears. Read the message in the error window.
