Thanks for your reply

I have executed these blow commands for your reference.
root@cloud-node001:~# telnet 172.16.206.50 8250
Trying 172.16.206.50...
Connected to 172.16.206.50.
Escape character is '^]'.
^]
telnet> q
Connection closed.
root@cloud-node001:~# showmount -e 172.16.206.50
Export list for 172.16.206.50:
/export *


right now my SSVM & CP is working fine after deleting both of them. but I
wanted to understand in what condition this 2 VM are not working ? I also
found that I am not able to mount the secondary volume manually it is
giving me connection timeout.

I am not able to understand why this SSVM suddenly gone off and come back
again ? due to this one of my VM status is showing in migration state.
could you please help me to fix this issue.

Thanks
AR
