Creating a snapshot template for software snapshots

The next step in setting up a software snapshot is defining the snapshot template. This template determines the cache to use for data sets that a snapshot job includes. The snapshot template is defined in a management set.

Before you begin

Complete the following tasks before creating a snapshot template:

To create a snapshot template

  1. Create a new management set file.

    1. From the File List panel, choose File > New and press Enter to display the New File Type subpanel.
    2. From the New File Type subpanel, type 1 (Management Set) in the selection entry field and press Enter to display the Object Type Selection subpanel  as shown in the following figure:
     File  Edit  Options  Console  Monitor  User  Help                         
    --------------------------------------------------------------------------
                          Management Set Edit - Summary                        
                                                                              
                                                       Created     Modified    
    Management Set : *** NEW FILE ***                  05/05/2008  05/05/2008

                    - ---------------------------------------- 

  2. On the Object Type Selection subpanel, type 2 (Snapshot) in the selection field and press Enter to display the Snapshot Managed Object Information subpanel as shown in the following figure:

  3. On the Snapshot Managed Object Information subpanel, complete the fields.For more information about the fields, see Snapshot-template-options-for-software-snapshots.

    Note

    On the Snapshot Managed Object Information subpanel, the Object field always shows the literal:

    BMCXBM.SNAPSHOT_TEMPLATE

  4. When you finish entering information, press Enter.The Snapshot template options subpanel is displayed as shown in the following figure:

    Note

    This subpanel allows you to specify SSI-assisted (hardware) snapshots. For prerequisites and instructions for performing SSI-assisted snapshots, see Enabling-hardware-snapshots. For a software snapshot, you do not use this option.

  5. On the Snapshot template options subpanel, leave 2 (No) unchanged in the selection field and press Enter.The Management Set Edit - Summary panel appears.
  6. Save the management set.
    1. On the Management Set Edit - Summary panel, choose File > Save.
