I’ve a question regarding extending Exchange vol on production server. The disk is reside on DMX 3 array.

What are the extending options do I have?

1. Would powerpath migration enabler work in cluster mode? Although this option is
2. Is DMX support virtual lun migration, I assume it don’t
3. Can OR replicate disk locally?
4. Presenting new LUN and ask Exchange admin to perform Mailbox migration at host level, but this might take a long time.

What’s your suggestion?
