To Update the ssh_known_hosts File

The management server /etc/opt/sun/n1gc/ssh_known_hosts file contains the name, IP address, and encrypted access keys for SSH-accessible servers. A stale or obsolete entry for a server in the /etc/opt/sun/n1gc/ssh_known_hosts file prevents SSH access to that server. The solution is to remove the entry for server from the /etc/opt/sun/n1gc/ssh_known_hosts file as follows.

Steps

1. Note the name and IP address of the inaccessible server.

2. Log in as root on the management server.

3. Edit the /etc/opt/sun/n1gc/ssh_known_hosts file and delete the entry for the inaccessible server.
