ZTD also generates failure messages.

[os10:notify], %Dell EMC (OS10) %ZTD-FAILED: Zero Touch Deployment failed to

download the image.

Troubleshoot configuration locked

When ZTD is enabled, the CLI configuration is locked. If you enter a CLI command, the error message configuration is

locked displays. To configure the switch, disable ZTD by entering the ztd cancel command.

OS10# configure terminal

% Error: ZTD is in progress(configuration is locked).

OS10# ztd cancel

ZTD DHCP server configuration

For ZTD operation, configure a DHCP server in the network by adding the required ZTD options; for example:

option domain-name "example.org";

option domain-name-servers ns1.example.org, ns2.example.org;

option ztd-provision-url code 240 = text;

default-lease-time 600;

max-lease-time 7200;

subnet 50.0.0.0 netmask 255.255.0.0 {

range 50.0.0.10 50.0.0.254;

option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;

}

host ztd-leaf1 {

hardware ethernet 90:b1:1c:f4:a9:b1;

fixed-address 50.0.0.8;

option ztd-provision-url "http://50.0.0.1/ztd.sh";

}

ZTD provisioning script

Create a ZTD script file that you store on an HTTP server. Configure the URL of the script using DHCP option 240 (ztd-

provision-url) on the DHCP server.

NOTE: Downloading the ZTD provisioning script is supported only on HTTP connections.

ZTD downloads and executes the script to upgrade the OS10 image, configure the switch, and execute a post-ZTD script to

perform additional functions.

● Write the ZTD provisioning script in bash. Enter #!/bin/bash as the first line in the script. You can use the sample script

in this section as a basis.

● For IMG_FILE, enter the URL path of the OS10 image to download and upgrade the switch. The image is written to the

standby partition.

● For CLI_CONFIG_FILE, enter the URL path of the CLI batch file to download and execute.

● For POST_SCRIPT_FILE, enter the URL path of the script to execute.

● ZTD fails and exits to CLI configuration mode if:

○ You do not specify at least one valid URL for the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE variables.

○ Any of the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE entries are invalid or if specified, the files

cannot be downloaded.

For the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE files, you can specify HTTP, SCP, SFTP, or TFTP URLs.

For example:

scp://userid:passwd@hostip/filepath

sftp://userid:passwd@hostip/filepath
