Has your unisphere login page got stuck and you cannot login to the unisphere environment to administer your box. There is an ssh command that you can use either through native ssh to the box if you have enabled it through the service options or by attaching the mini serial cable to the unit and using hyperterminal or similar to login to it.
Once logged into the vnxe interface in order to restart the unisphere environment enter the command svc_restart_mgmt and hit enter this will restart the webui which will take several minutes to complete.
This operation only restarts the webui and does not affect the storage in anyway so you can safely perform this action during production hours.
