● In the ZTD provisioning script, enter the URL locations of an OS10 image, CLI batch file, and/or post-ZTD script. Enter at least one URL, otherwise the ZTD fails and exits to CLI Configuration mode. ZTD guidelines ● You can store the ZTD provisioning script, OS10 image, CLI batch file, and post-ZTD script on the same server, including the DHCP server. ● Write the ZTD provisioning script in bash. ● Write the post-ZTD script in bash or Python. Enter #!/bin/bash or #!/usr/bin/python as the first line in the script. The default python interpreter in OS10 is 2.7. Use only common Linux commands, such as curl, and common Python language constructs. OS10 only provides a limited set of Linux packages and Python libraries. ● ZTD is disabled by default on automatically provisioned switch fabrics, such as Isilon backend, PowerEdge MX, and VxRail. Cancel ZTD in progress To exit ZTD mode and manually configure a switch by entering CLI commands, stop the ZTD process by entering the ztd cancel command. You can enter ztd cancel only when ZTD is in a waiting state; that is, before it receives an answer from the DHCP server. Otherwise, the command returns an error message; for example: OS10# ztd cancel % Error: ZTD cancel failed. ZTD process already started and cannot be cancelled at this stage. Disable ZTD To disable ZTD, enter the reload command. The switch reboots in ZTD disabled mode. Re-enable ZTD To automatically upgrade OS10 and/or activate new configuration settings, re-enable ZTD by rebooting the switch using the reload ztd command. You are prompted to confirm the deletion of the startup configuration. NOTE: To upgrade OS10 without losing the startup configuration, back up the startup configuration before ZTD runs the provisioning script. Then use the backup startup configuration to restore the previous system configuration.
