Symptoms include, but may not be limited to: VM Import from External Connection Import to NativeEdge of a VM from vCenter to Dell Automation Platform fails. Imports using the vCenter IP address, or its fully qualified domain name (FQDN) into the orchestrator results in a failure. Orchestrator logs reports a DNS lookup failure: failed to download vm file disk-0 vmdk from vcenter 10.10.10.22:443: Get dial tcp: lookup esx22.domain.lab: no such host
MultiDomain environments require additional Domain Search lookup attributes. DNS lookups may fail due to the Orchestrator attempting to resolve a host using the DNS suffix (example: domain.edge ), while the DNS records existed under another suffix (example: domain.com ). When multiple domain resolutions are required within a network, each domain must be explicitly defined. This can be done client side when static IPs are used, and server side if DHCP is in use.
When using multidomain lookups, it is recommended to configure a central list of domains to search from the server side. This can be accomplished using DHCP. Microsoft DHCP environment Note: By default DHCP Option 119, as defined by RFC 3397 , is not enabled by default. Connect to Microsoft DHCP Manager mmc (Add the DHCP server if it not already displayed). Right-click IPv4 and select Set Predefined Options . Click Add to define a new Option Type and define it. Name: Domain Search List Data type: Byte Code: 119 Description: Domain Suffix Search Order Confirm with OK . Under the DHCP Scope, Scope Options , Scope Options does not list "119 Domain Search List" as an available option. Select Option 119, Data Entry Byte Format should be Hexadecimal , and each domain must be passed in a similar hexadecimal format There are free online strings to hexadecimal converts, with Byte Prefix. From Linux, python may be used (Replace "domain.lab" with the wanted domain): python3 -c 'd="domain.lab"; print(" ".join(f"{len(x):02x} "+ " ".join(f"{ord(c):02x}" for c in x) for x in d.split(".")) + " 00")' The DHCP client may require a DHCP renew, or reboot, to acquire the new attributes.
