Setting up DR550 for remote mirroring
Review the DS4000 redbook for remote mirroring setup. The redbook can be found at http://publib- b.boulder.ibm.com/abstracts/sg247010.html?Open. Chapter 9 includes information on enhanced remote mirroring. You will to need to set up remote mirroring for all logical volumes, including the TSM data base, log files and the entire TSM storage pool. Depending in the capacity, there could be as many as 22 volumes. All must be included in the mirrored set.
When remote mirroring is activated, data will be sent to the remote (secondary) DR550 via the SAN. The connection must be made between port 10 in the SAN switch (both switches is a dual node configuration) in the primary DR550 and port 10 in the SAN switch (both switches in a dual node configuration). This connection is shown in the diagrams below. Port 10 has been configured in the factory as an
The cable or cables used between the primary and secondary sites are the responsibility of the user. IBM cabling guides provide the specs required for these cables.

If you desire longer distance, you can implement extension technology such as that available from McData or similar vendors. This includes DWDM and CWDM technology. The distance can be extended up to 100 km. This technology is not included with DR550, but must be sourced from the appropriate vendor. When using Metro Mirror or Global Mirror over network technologies such as Fibre Channel, Ethernet/IP,
