MD1000: Changing from Split to Unifified Mode.

I think this post has a partial answer.

The post above talks about going from unified to split while you want to do the reverse. The one thing to look into is the cabling. Unified mode will only use the EMM is slot 0 (EMM in slot 1 will only be used for array management in case of any failure but not for data).

I think you should be able to power down the enclosure and server, move the cable from EMM 1 to EMM 0, and power up enclosure and server. The disks groups and data should be visible. You might have to import them into the new controller. As long as you don't re-initialize the disks, you will not lose the data:)

(Disclaimer: I have not tried this out personally. Reading the note above and the topic disk migration  (pg 23) in the document "http://support.dell.com/support/edocs/systems/md1000/wh_paper/SAS%20MD1xxx.pdf " gave me this thought)

Hello. Did you get an answer for this?

I am also looking for an answer for this. Has anyone tried this before?

1. Shutdown server

2. Shutdown MD1000

3. Switch from split to unified mode.

4. Power on the MD1000.

5. Power on server.

Is the data still exists?

fadzilj,

The data will not be lost. You will have to re-import the disks to be able to see the VDs.
