Too many users logged in! Please try again later. This is the wonderful greeting you get from a NetApp when another user is logged in to the console. and if they forget to logout you will be not able to login.
Today i have faced this problem and almost frustrated finally i found this on web and felt like sharing with all. In case if you are getting the above message you can use the command below form any server from which your filer is accessible.
rsh <filername> -l root:<password> logout telnet
