Solution

For N+1 to work check the following:

    
• The slave and master must be the same model and running the same software version of System Director.
    
• The master and slave must use static IP (DHCP addresses are not supported).
    
• Master and slave controller must be on the same IP subnet.

Setup Configuration:

You must configure all the masters first.

    
1. Enter the CLI through console or SSH
    
2. Enter configuration mode by typing "configure terminal"
    
3. Now start N+1 by entering "nplus1 start master"
    
4. To verify if N+1 has started exit configuration mode type "exit" and then "sh nplus1"

Setting up slave:

    
1. Enter the CLI through console or SSH
    
2. Enter configuration mode by typing "configure terminal"
    
3. Now start N+1 by entering "nplus1 start slave"
    
4. Supply host name and IP "nplus1 add [hostname] [IP]"
    
5. Enter password
    
6. To check that the controller was added "do show nplus1"
    
7. Enable master on slave "nplus1 enable [IP]"
    
8. "exit"
    
9. To check if master controller has been enabled "show nplus1"
