EVA 4100: Changing controller

Hi,

I wanted to change the Controller for a set of Vdisk to run on Controller B. I have changed the preferred path from A to B, out of the 3 Vdisk, 1 is still showing the managed controller as A, while the other 2 Vdisk is now managed thru Controller A. How do I make it work?

Hi,

Check the vdisk and his connections to the server(s).

Check also on the server how the connect to the controllers.
It is possible that the server(s) are fixed on a specific path to the controllers.

Example, 3 server connected to an eva with multipath but path A is the preferred path and connected to controller A.
If you change the prefered owner to controller B but you do not change the preferred path, your lun could by returned to the controller A as this controller has the most IO for this lun.

Hope this helps.
