HP XP7 Replication Manager User Guide (TK981-96013, May 2014)

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.
