Hi Khoi,
The reason why this happens was explained by Alan Bishop in this thread[1]. I'll mention this bug in the next cinder meeting and hopefully Dell team will work on this bug.
Cheers,

Hi,Khoi, the PowerStore doesn't support volume migration. The related information is as following:

Hi, Khoi,
    Can you give more details about this bug:
     if the volume need attach to an instance, and can you give the log to me? and what's your action and config file?

Hello.

How to reproduce it:

Retype type volume to change cinder backend

**Environment**:

Openstack Xena with cinder backend source as Dell Powerstore and destination as DellSC.

It means I change volume type from Powerstore to volume type on DellSC

Do we have a plan for support volume migration?, thank you.
