it means that the San is not accessible on your network. Are you able to ping the San IP from your workstation?

Hi ,

I think it is more of a SAN level configuration problem, Since it drops off after a while. did you check the VMkernel and vobd.log .??? may be you could post the vmkernel and vobd logs.

Thanks,
