Overview of the ESS Copy Services Web interface

The ESS Copy Services Web interface is used to create and manage Copy Services tasks. This Web interface consists of a number of HTML screens and Java™ applets and can be accessed from a standard Web browser.

A Copy Services task consists of:

The IDs of the source and target disks involved,

The operation to be performed:

oEstablish FlashCopy pair o Withdraw FlashCopy pair o Establish PPRC copy pair o Suspend PPRC copy pair o Terminate PPRC copy pair

Several other options (that is, . whether or not to perform background copy).

For example, to create a task named fctask that establishes a FlashCopy relationship between two disks with the ‘no copy’ option:

1.Select the LSS in which the source and target disk reside.

2.Left click the source disk, right click the target disk, and right click againto display the Options menu.

3.Select Establish FlashCopy pair from the first menu and click Next.

4.Select Do not perform background copy if checked from the second menu and click Next.

5.Enter fctask as the task’s name and a task description and click Save to store the task on the Copy Services server.

You can execute the task from the Tasks menu of the Copy Services Web interface, or from any server on which the ESS Command Line interface is installed. You can install the command line interface on any server attached to the ESS via TCP/IP.

A basic FlashCopy task can only contain disk pairs from one LSS. You can combine several basic FlashCopy tasks into one group task to establish or withdraw FlashCopy pairs in several LSSs. Please note that the source and target disks of a FlashCopy pair always have to reside in the same LSS.
