/mcpNotes for Basic and Touchless Installs After you install a new node on an existing cluster, if you plan to utilize Cisco CallManager or Cisco TFTP services, we recommend that you restart all the phones in your cluster to get the latest ITL file. If you are using a Certificate Trust List (CTL), you will also need to update this file manually by running the utils ctl update CTLFile CLI command (using Tokenless CTL) or by updating the file via the CTL Client (Legacy USB tokens). After you update the CTL file, you must restart the phones so that they can download the latest CTL file. For additional details on the CTL File, see the “Cisco CTL Client Setup” chapter of the Security Guide for Cisco Unified Communications Manager. Important • You can collect the logs from RTMT of a new node added to the existing FQDN cluster, only when you restart the trace collection service. When you sign in to Unified RTMT without restarting the trace collection, the following error message is displayed: Could not connect to 'Server' <new node name>. • If you install a new node to an existing cluster where the IM and Presence server is not upgraded to the supported version or if the IM and Presence server has been decommissioned, the following error message is displayed: "Add failed. Upgrade and migration for Cisco Unified IM & Presence Servers that are associated with this cluster appears to be pending (not complete). Please make sure upgrade and migration of all IM & Presence servers is completed successfully before adding servers to this cluster. Please check for any unused IM & Presence Application Servers and delete them”. Note A touchless install cannot be used to simultaneously install multiple Unified Communications Managers and multiple IM and Presence Service nodes. The following scenarios are supported: • Installing only multiple Unified Communications Manager nodes • Installing only one Unified Communications Manager node (publisher) and multiple and IM and Presence Service nodes If you need to simultaneously install multiple Unified Communications Manager and IM and Presence Service nodes, you must use one of the above scenarios and install additional nodes manually.
