The task screen provides detailed information to the operator on the status of tasks for the Platform Server System. This screen is broken down into two sections, standard tasks and maintenance tasks.
Figure 30 - Task Screen
The task information grid is controlled by (3) three filter boxes at the top of the task grid. Each filter box has a number of drop down options.
Task Status Filter – This filter allows operators to filter the tasks in the grid to a particular status. The default status is ‘Running and Pending’.
Task Type Filter – Used to filter tasks of a particular type (see table below).
Platform Space Filter – Used to show any jobs that are operating on a particular Platform Space.
The Task Information Grid provides detailed information about task jobs currently running or the status of jobs already run on the Platform System. Each Task has a number of Columns which are described below:
Task – The name of the task
Priority – The priority (Low, Medium, High) is used to determine the order in which jobs with the status of ‘Queued’ are run.
Status – Job status tells the operator the current condition of the job. Valid Status’ are:
Table 15 - Task Status Types
Source – Typically describes the source Platform Space but can also show the source as a Tape Drive or other device. This is the source location that the task is getting the data.
Target - Describes the destination location for the particular task type.
Speed – Lists the speed of the task operation. Task speeds are Slow, Medium and Fast which are indicators of how much Platform resources are used to conduct the operation.
Start Time – The start time of the particular job. If this is a recurring job, the start time is automatically updated each time an instance of the job is completed.
Progress – The progress column displays an indication of how far along the job is in comparison to the entire job. The system will attempt to provide a percentage complete for many jobs.
Error – Displays a URL which can be clicked upon to see the full error message for this particular job. If no error occurred, the column will be blank.
The task jobs in the task grid options which are dependent on the task status:
Stop – Attempts to stop a job that is currently running. Please note, tape jobs cannot be stopped from the task screen. If an administrator needs to stop a tape task, the will do that in the Tape screen by right-clicking on the Tape Drive and selecting Stop.
Edit – Allows an operator to update the parameters of a job waiting to run.
View Log – Shows the detailed historical log of the job operation.
Delete Task – Stops the current operation and deletes the job from the task system.
Maintenance Tasks run in the background at specified time intervals to keep the server running well and at peak performance. The specific activities in maintenance include defragmenting disks and performing error checking on storage groups.
By default, the system enables one storage maintenance task that runs on all Storage Groups connected to the server and is called ‘Maintenance’. If the administrator wishes to create separate maintenance tasks per storage group, the will use the Storage Group Screen to update the maintenance times on each storage group individually.
The Maintenance Task Information Grid shows the following:
Task – The task name, Maintenance.
Enabled – This check box indicates if the maintenance task is currently scheduled to run based on the Scheduled Start Time.
Target Storage Group – The name of the storage group for the maintenance task. If an asterisk ‘*’ is displayed, it means that this maintenance task will apply to all storage groups attached to the system.
Target Server – The Platform Node that the maintenance task applies to. If an asterisk ‘*’ is displayed, it means that this maintenance task will apply to all nodes in the Platform Infrastructure
Scheduled Time – This is the start time of the maintenance task.
Day(s) – The days of the week that maintenance is intended to run. The default task runs each day of the week.
The administrator has the following right-click options when working in the system maintenance grid:
Edit – Used to update the schedule settings for the maintenance task. The system will bring up a window allowing the administrator to make changes to the maintenance schedule:
The system will allow the administrator to enable or disable the maintenance task by checking the ‘Enabled’ checkbox. They can also update the start time of the maintenance task and the days of the week that the maintenance will start.
History – See a list of each time the maintenance task has run and allow the administrator to view the detailed maintenance logs. The system brings up a grid with a list of each maintenance task that has run on each storage group.
The columns listed include the Start and End time of each job, the Platform Server Node Name, the Storage Group and a column indicating if the job is currently still running. If the ‘Running’ checkbox is checked, that means that the maintenance job is still executing. The ‘Error’ column will provide an indication of there was a problem with the maintenance job. If something is listed in the column, the view log command below can provide details.
If the administrator wishes to see more detail on each maintenance job, they can right-click on a line in the grid. The system will then bring up the option to ‘View Log’.
The History Log shows a detailed line-by-line description of the job execution status.
