NetScaler appliances in a high availability setup

You can configure a high availability (HA) setup on the NetScaler appliances with a SafeNet HSM configuration in either of the following two ways:

  • First, configure a SafeNet HSM on the two nodes, using the same HSM and partition. Then create an HA pair. Finally, add the NetScaler configuration, such as keys, certificate-key pairs, and virtual servers, on the primary node.
  • If a SafeNet HSM is already configured on one node with the NetScaler configuration, add a similar configuration on the other node. Copy ‘/var/safenet/sfgw_ident_file’ from the first node to the other and restart the safenet_gw binary. After the gateway is up and running, add the nodes in an HA setup.
