IBM manual Setting up DR550 for mirroring back to original site

IBM System Storage DR550 Version 3.0 ------ 17 March 2006 Page 80

7.If needed, you will need to change the IP address within the application server (the server running some type of content management application) to point to the remote DR550.

For Dual Node (HACMP) implementation (Assuming AIX servers are not operational):

1Start the server (power on) in the secondary DR550.

2When the power up cycle is complete and AIX has completed its startup procedures, using the integrated console, logon to AIX using the DR550 userid

3Switch to Root and enter the appropriate password

4 Start HACMP services on both nodes o smitty hacmp

o system management (C-SPOC) o manage HACMP services

o start cluster services

o select both nodes of the 2nd entry of the screen ‘‘start cluster services on these nodes….’’

5 This will bring up TSM as part of cluster services then Login (in approx. 10 minutes) as an admin and check out TSM server and validate all information and data.

6 At the TSM prompt the TSM administrator can run q lic, q dbvol, q loglov, q db, q log, q stat, q sys.

7 If needed, you will need to change the IP address within the application server (the server

running some type of content management application) to point to the remote DR550.

Setting up DR550 for mirroring back to original site

At this point in time you will have the DR550 operational at the secondary site. All new updates will be coming to this site. The decision that was made prior to this determines if the current secondary site becomes the new primary site or takes the role of the secondary site again once the issues are addressed at the original primary site and all current data is transferred to it.

Either way, you must now redo the Enhanced Volume Mirroring relationship (RVM). As mentioned in the above paragraph, all new data is currently being sent to the secondary site. To make sure that the data is not overwritten and that it is propagated to the other site correctly, you must now remove all RVM relationships from the storage systems. This can be done by just right clicking on any logical drive that is part of a mirror relationship. Select Remove Mirror Relationship -> Select All -> Remove -> Yes. This will remove all the mirror relationships.

NOTE: You may receive an error if the other Storage Server is not operational. When it has finished, the storage server that has the newest data becomes the primary site (source) and the storage server that had technical issues becomes the secondary site (target).

Recreate the RVM relationship using the storage server with the newest data as the primary and the other storage server as the secondary. NOTE: MAKE SURE THAT YOU CREATE THE RELATIONSHIP CORRECTLY. THE STORAGE SERVER WITH THE NEWEST DATA IS NOW THE PRIMARY (SOURCE). Do this by following the same steps as you did to set up the remote volume mirroring relationship taking into consideration which storage server is now the primary and which is the secondary.
