OAKERR:7007 when start guest machine VM in ODA

Hi,

I tried to start a windows 2012 VM which was running before in my ODA Virtualization platform using the oakcli command below, but it prompts OAKERR7007 error

[root@server1 /root]# oakcli show vm

          NAME                                  NODENUM         MEMORY          VCPU            STATE           REPOSITORY

        win2012                                 0               4096M              2            OFFLINE         odarepo1 

[root@server1 /root]# oakcli start vm win2012

Start VM : win2012 on Node Number : 0 failed.

DETAILS:

        Attempting to start vm on node:0=>FAILED.<OAKERR:7007 Error encountered while starting VM -  Error: long too big to convert

Anyone know the cause?

Thanks
