Hello,

You have not provided enough infromation for a helpful response. 

Which array are you running?

Which firmware version?

Linear disk group or virtual disk group?

Consider that if you only have one linear or virtual disk group, you will get better performance if the disk group remains on controller A. If you are moving the disk group due to future growth on the system it may make sense to move the ownership of the disk group. However, unless this is a very old system, the MSA is ALUA and active on both controllers.

Cheers,
Shawn
