When you get the below error message in your broswer and you can not manage your environment anymore. Just Reboot your EMC Celerra Control Station with the following command in a console session.

reboot

this can be carried out without problems because only the Control Station will be rebooted. The data movers will stays online.

Please note that this procedure requires a reboot of the CS. This should have little visible impact to Data Mover end-user access. However, it will impact administrative users and Celerra Manager access temporarily – only about 5 ~ 10 minutes while the CS reboots. Therefore, it is recommended that this reboot be done at a convenient time. If it is not going to be convenient to reboot the CS, then consider using the command line version procedure as an alternative.
