When access to an HCP Node through the HCP System Management Console or
management API is not possible, authorized service providers can use SSH login to access the
node.
Note: If SSH is used at the customer site, all SSH keys for a node are updated when
Java Virtual Machine starts on the node. The same is true when nodes are swapped.
Important: By default, SSH login is
disabled. Disabling SSH enhances security, but also increases the amount of time required
for an authorized service provider to diagnose and resolve issues. For information, see
Enabling SSH.
