Create EVM Job

Overview

The Create EVM Job page appears when you click the New Job button that appears on the EVM Jobs View, EVM Network View, and EVM Storage View. The page is organized like a wizard to guide you through the steps of creating an EVM job. The information below will assist you in completing the steps. For information on a specific step, click the step number: 1 2 3 4 5 6.

 

STEP 1

Job Name - mandatory entry

  1. Enter a name for your EVM job. The wizard will create the job file using this name. Choose a name that reflects the type of activity the job will perform.

    Examples

Created By - optional entry

  1. Enter the name of the organization or person who is creating the EVM job. The name can be an organization, person, or a combination.

    Examples

 

STEP 2 Unit Replication Method - mandatory selection

  1. Select the unit replication method that is appropriate for your job.

    Notes



 

STEP 3 Units to Replicate - mandatory selection

  1. Select one or more units that you want to replicate in this job.

    Notes



 

STEP 4 Application I/O Handler - optional selection

Default

The default selection is None. In this case, the EVM job will not communicate with an application to suspend and resume file I/O.



Enabling the Application I/O Handler Feature

  1. To enable the feature, scroll through the list of available computers and select the relevant Application Server. This is the server that is performing file I/O with the units that you want to replicate in this job.



  1. In the Pre-split Command box, enter the path and file name of the I/O handler that will suspend I/O just before the BCV units are split from the source. In most cases, the I/O handler is a script file that runs the required I/O commands. See notes below regarding path and file names.

  2. Select the EVM Job Mode. The default is Wait. This instructs EVM to wait for the return of a completion code from the I/O handler before EVM proceeds with the split. To instruct EVM to proceed with the split without waiting, select Don't Wait.

  3. In the Post-split Command box, enter the path and file name of the I/O handler that will resume I/O after the BCV units are split from the source. In most cases, the I/O handler is a script file that runs the required I/O commands. See notes below regarding path and file names.

  4. Select the EVM Job Mode. The default is Wait. This instructs EVM to wait for the return of a completion code from the I/O handler before EVM proceeds with its next task. To instruct EVM to proceed without waiting, select Don't Wait.

    Examples

    /sales/suspend_transactions.sh

    /sales/resume_transactions.sh

    Notes

 

STEP 5 BCV Mounting - optional, but recommended selection

Default

The default selection is None. In this case, the BCV units that EVM creates will only be recognized by the StorageWorks subsystem. They will not be mounted on a server or be recognized by host operating systems or application programs.



To Mount BCV Units on a Server

  1. To mount the BCV units, scroll through the list of available computers and select the one you want. If you are creating this job to perform a tape backup, the computer that you select should be the tape backup server.

  2. In the mount as box, enter a mount point (directory) and slice (partition) for each unit that you are replicating in this job. Enter the mount points in the same sequence that the selected units appear in Step 3.





 

STEP 6 Backup Handler - optional selection

Default

The default selection is None. After BCV units are created and mounted on a server, EVM will not issue a command to a backup application to start a tape backup.

Enabling the Backup Feature

  1. In the Backup Command box, enter the path and file name of the backup handler. In most cases, the backup handler is a script file that runs the required backup application job. See notes below regarding path and file names.

  2. Select the EVM Job Mode. The default is Wait. This instructs the EVM job to wait for the return of a completion code from the backup handler before it ends. To instruct the EVM job to end without waiting, select Don't Wait.


IMPORTANT: Running EVM Jobs. To run the EVM job with the backup handling feature enabled, you must have already created the script files that you reference.


 

Save

  1. To save the EVM job, click Save. The Confirm and Save EVM Job page will appear. You can confirm that your choices are correct and then save the job.

 

Back (clear entries)

  1. To clear all entries and return to the EVM Network View, click Back.
