SAN switch migration in NetApp Storage environment
Posted on 2013-06-18
We are doing a SAN migration project wherein we will be replacing the SAN switches from broacade to Cisco Nexus 5596UP. The Storage array is NetApp v3170 running ONTAP version 8.0.2 P1 7-mode. Now on each netapp controller we have 4 fiber channel ports out of which 2 are used and 2 are unused. All these ports are configured as targets. The name of the controllers are netapp1a and netapp1b (each controller having 4 fiber ports) and configured in single image mode.
Now, I want to connect the unused 2 ports from each controller to new switches without disrupting the current connections, currently the initiators or hosts are connected to 0a and 0d while 0b and 0c are not in use. Once this is connected, is there any else I need to worry from NetApp perspective for enabling that unused fiber ports. I will do the zoning on the new switches.
After this, I have to work on moving the SAN connected hosts (SQL servers running on windows 2008 SE) from old switch to new switch. Can anybody share the steps on what needs to be done to migrate the servers online without taking the downtime. As these servers are multipathed, I would like to know how I can move one path at a time so that there is less downtime of the server involved in the migration. If any of the experts has done this before, please share the procedures or steps of doing that on cisco + NetApp configuration?
