Creating an ESE Sizer session and adding copy sets

The ESE Sizer session supports analyzing space requirements for DS8000 Extent Space Efficient (ESE) FlashCopy and Safeguarded Copy.

1. Follow these steps to create a ESE Sizer session:
   1. In the menu bar, click Sessions.
   2. On the Sessions page, click Create Session.
   3. In the Create Session window, select the following options:

      Hardware type

      Select IBM DS8000.

      Session type

      Select ESESizer.

      Session name

      Enter a name to identify the session. The session name can be up to 58 alphanumeric characters. The default name for a new session is newsession.

      Site 1 Location

      For each site that is in the session, select the location for the site or None. The site location, if available, is set by storage system on the Storage Systems page.

      You can associate a location with each storage system and each site in a session. This site awareness ensures that only storage systems that have either a matching site location for each role or have no defined location are displayed in the copy set wizard.

      Session image

      Shows an image that represents the session. The session image is displayed when you select a session type. The image is a visual aid to help you create your session.

      If you selected a location for the site that is in the session, the site is labeled with the site location. If you did not select site locations, the sites are labeled with Site x, where x is the site number. You can hover the mouse pointer over the site location to view the text in a larger format.

      If the H1 role does not have an assigned location, all storage systems are displayed for selection.

      Storage systems that are assigned to a location are listed under the location name. Storage systems that are not assigned to a location are listed under the None. column.
