Copy Services functions across a 2105 and 1750

Copy Services functions that are performed using either the DS Storage Manager or DS CLI are designed to interact with both the 1750 and the IBM^® TotalStorage^® Enterprise Storage Servers (ESS) Models 750 and 800.

Most Copy Services functions that are available on the ESS 2105 are also available in the 1750 and in open systems and zSeries^® environments.

Consider the following guidelines:

To perform Copy Services functions between machine types 2105 and 1750, you must configure a Copy Services domain on the DS Storage Manager or DS CLI.
To connect to the 2105 Copy Services domain on the ESS, all interfaces that you use require an authenticated login procedure to access Copy Services functions across the storage complex. The authentication is performed by using a user name and password that was created with the ESS Specialist. Therefore, the existing user name and password that was created with the ESS Specialist for the 2105 Copy Services domain for which you will be working must match the user name and password on the management console that is connected to the 1750. Otherwise, you must add them using either the DS Storage Manager or DS CLI as part of the procedure for adding a 2105 Copy Services domain to the storage complex.
To manage Copy Services across the 2105 and 1750, you must install licensed internal code version 2.4.2 or later on the ESS Model 800.
The 1750 does not support remote mirror and copy (formerly PPRC) operations with an ESCON^® link. Therefore, if you want to configure a remote mirror and copy relationship between the 1750 and 2105, you must use a FCP link.
