Cant able to access filer View

Hi All,

1. We have tried to offline some volumes in FAS3050/7.3.3 ontap  and it is not successful status moved to ``UNMOUNTING".

2.Due to that we cant access a Volumes list in FilerView and cant do anything in CLI using Telnet/ssh session.

3. But the filer is continuing its services to host .

Please help me to fix this issue.
