When you create a job, EVM not only records your basic instructions, it also determines if there are sufficient resources to run the job at that point in time; and, it records details of the existing storage configuration.
When planning to run EVM jobs, you must consider that changes can - and will - occur in the storage configuration after jobs are created, and that those changes may make it impossible for some jobs to be successfully run later.
To solve the problem of frequent changes in storage resources, EVM provides two features on the EVM Jobs View page: page: job resource icons and a job validate button. When used properly, these features can prevent EVM jobs from conflicting with each other, and allow you to re-use EVM jobs even after many storage configuration changes.
Job Resource Icons
The job resource icons have the following meanings:
When last validated, there were sufficient StorageWorks resources to run this job. | |
StorageWorks resources may have changed since this job was last validated. | |
When last validated, there were not sufficient StorageWorks resources to run this job. |
IMPORTANT: When browsing to previously displayed pages, be sure to refresh the page before interpreting job resource icons.
Validate Button
When you validate a job, the first thing EVM does is to analyze the job relative to the current storage configuration. If the job can be run without change, or if EVM changes the detailed job parameters so that the job can run, the job resource icon changes to a green dot. If the job cannot be run given the current resources, the job resource icon changes to a red exclamation point.
See Job Validation Examples for further information on use of this feature.
