Access the customer's system via Support Mode

Follow this procedure to gain access to the customer’s system via Support Mode.

1. SSH into the proxy server (tacp-proxy.cp.lenovo.com) using a valid Support ID.
   For example:

   Note

   marc.lavergne is an example Support ID in the following:

2. The SSH session CLI displays. Enter the following command:

   ssh -p [user’s port number] cldtx_support@localhost

   where the user’s port number is the number shown in the user’s Cloud Controller Support Mode screen.

   In this example, the user’s switch port number is 11076.

3. Access a storage or compute node by first looking for the IP address of the node under the hardware section on the Cloud Controller or at /var/lib/dhcp/dhpcd.leases via the CLI. Then use the following command to connect to the node:

   ssh -i ~/.ssh/<pri_file> cldtx_support@<ip>

   where <ip> is the IP address of the node you are trying to connect to and <pri_file> is the private key file.

4. If the configuration has dual switches, -b needs to be added to the node connect command, thus making it:

   ssh -b 192.168.1.1 -i .ssh/<pri_file> cldtx_support@<ip> #primary

   ssh -b 192.168.1.2 -i .ssh/<pri_file> cldtx_support@<ip> #secondary

   Rather than looking up the Multi-enclosure Link Aggregation Group (MLAG) IP for the switch, you can run the following commands:

   source /etc/tacp/tacp_switch_resource.shecho $MLAG_VLAN_IPssh -b $MLAG_VLAN_IP -i .ssh/<pri_file> cldtx_support@<ip>
