Status 2001 on a cluster server

Hi All,

I am using win 2008 & 2012 servers and NBU 7.6.0.1 in a cluster server, I got the error 2001 which is nothing but NO DRIVES ARE AVAILABLE, but i have plenty of drives and all are working fine and it is a FULL backup.

In my environment we are using all windows severs, No Unix Servers.

Anyone please suggest me how to getrid of this issue.

Thanks in Advance
