iDRAC9 Security Configuration Guide
Auto-discovery
The Auto-discovery feature allows newly installed servers to automatically discover the remote management console that hosts the provisioning server. The provisioning server provides custom administrative user credentials to iDRAC so that the un-provisioned server can be discovered and managed from the management console. For more information about provisioning server, see the Lifecycle Controller Remote Services Quick Start Guide available at www.dell.com/idracmanuals.
Provisioning server works with a static IP address. Auto-discovery feature on the iDRAC is used to find the provisioning server using DHCP/Unicast DNS/mDNS.
- When iDRAC has the console address, it sends its own service tag, IP address, Redfish port number, Web certificate etc.
- This information is periodically published to consoles.
DHCP, DNS server, or the default DNS hostname discovers the provisioning server. If DNS is specified, the provisioning server IP is retrieved from DNS and the DHCP settings are not required. If the provisioning server is specified, discovery is skipped so neither DHCP nor DNS is required.
Because Auto-discovery relies on iDRAC publishing unencrypted information for discovery purposes and should only be required in initial provisioning, it is recommended as a security best practice that this feature be disabled unless needed. If auto-discovery is necessary, DNS is the preferred method.
