CSV redirect access

Hi,

I have a simple configuration, two windows 2008 R2 cluster with iSCSI shared backend. The CSV is online when I created, however, after I migrate the CSV to the other node, the status is rediect access. There is a error in eventlog complains it can not find the physical disk (event id 1034). The node is the owner before migrate and the disk is right there and I can read the signature. So what is the problem?

BTW, I passed the validation test without errors.

Thanks,

Tony
