I have done the basic configuration on asa 5520. For active active availablity i changed the mode to multiple context mode and encountered some issues with the setup and i restored back to single context mode by the command mode single in global config mode.
After the asa rebooted i am not able to access the asa through telnet, http or asdm.
I tried with console cable as well but could not get in to the asa. Can any one please let me know how can i access the asa
