LSI Syncro CS - how to transfer VD from Node B to Node A?

2 posts in this topic

Hi, 

I have LSI Syncro CS 9271-8i installed and I found small issue here:

I created a Node A and it has a shared Virtual Disk (VD).

Now, when Node A reboots, the VD is being transferred to peer Node B and the VD will stay in Node B - no matter node A is up or not.

Is this normal? Any expert here knows how to transfer VD from Node B back to Node A when A is online?

Below is the information --- I would appreciate it if anyone here could give me some feedback. Thanks.

If you reboot node B does it move back to A? In windows there was also an area to manually move it back and forth.
