When you select a storage system in Path Provisioning, the management server displays all the information relevant for provisioning with respect to the storage system selected. This information includes:
•Mapped, unmapped and unmasked (mapped to one or more storage system ports but not associated to any host initiator port) volumes of the storage system,
•Already masked LUNs of the storage system and the front end ports of the storage system (possible candidates for LUN mapping step)
•Hosts that are reachable (hosts belonging to the same fabric as the storage system) along with their HBA and host initiator ports. Single multipathing functionality is supported.
•Existing zones to which the ports of the storage system belong are displayed. If the Host and the Storage System belong to multiple fabrics, zones of all those fabrics are displayed.
The above information is displayed in several different panes (storage system, host, volume, LUN and zone panes). You can select relevant information from each of these panes (such as, which volumes to be used for the LUN Mapping Task). Each of these selections potentially can create a provisioning task to be performed. You can create a job that contains one of the following:
•A single task of one type (such as, Map LUN)
•Set of tasks of the same type (such as, multiple LUN Mapping)
•Multiple LUN Masking tasks or a job consisting of several tasks of different types (such as, Map LUN, zone required ports, mask LUN, which go together as a combination).
•You can also create multiple jobs each consisting of multiple tasks of different types.
The jobs can be executed immediately or can be scheduled to start at a later time. Jobs with all its required details (such as, parameters to invoke Provider Service methods) are stored in a job queue. The scheduler, at the scheduled time, retrieves the job from the job queue and performs the tasks of the job using the details stored in the job.
The status of each of the job can be one of the following, and it is displayed in the State column in the Provision Job section of the screen (lower pane):
•Create - The job has been created, but it will not be executed. The job cannot be viewed by others and it is deleted when the Web browser is closed. See ”Scheduling Provisioning Jobs” on page 399 for information about changing the state of the job from “create” to “scheduled”.
•Scheduled - The job has been tasked to execute at a specified time and date. Jobs are
assigned a scheduled state after you select the job and click the Execute Job button (
) button.
•Started - The job has started. You cannot delete a job once it has started.
•Failed - The job failed.
•Ended - The job has finished.
