Celerra NAS service not working properly

Hi Guys,

Many of the management commands are not working and end up in a error stating "critical 0: query schedule all", even i tried restarting the NAS service but still the restart was not complete.

[nasadmin@NSG ~]$ /etc/init.d/nas stop

umount: only root can unmount /dev/hda5 from /nas

ERROR: Unable to unmount /nas

umount: only root can unmount /dev/nde1 from /nbsnas

ERROR: Unable to unmount /nbsnas

NAS:/etc/init.d/nas: ERROR: Failure to stop nas service has left NAS services

in an undefined state.

Please reboot the control station.

For reboot , i get similar error message.

[nasadmin@NSG ~]$ nas_cs -reboot

Connect Failed:: Connection refused

Error 13958709250: The Celerra management service is not responding for task Reboot control station..

is there any way to reboot the CS, without doing it physically?

Thanks

Saran
