Reinitiate Auto-discovery
9
The iDRAC discovers the provisioning server in one of three ways: DHCP vendor options, DNS SRV
lookup, or default DNS entry. There is also a fourth option—manually configuring the provisioning
server. Configuring the provisioning server address in the reinitialize request will bypass the discovery
step, and the iDRAC will proceed directly to handshake. Setting the provisioning server is very useful if
there are multiple provisioning servers in the network and the user wants to move a server from the
control of one provisioning server to another. It can also be used in situation where the user does not
have control of the DHCP or DNS services.

There are two ways to set the provisioning server: setting the provisioning server attribute, or
reinitiating auto-discovery. You may choose either one to set the value of the provisioning server.
Setting the provisioning server attribute
The following WSMAN command will set the IP address or host name of the provisioning server on the
iDRAC.
EXAMPLE:
winrm i SetAttribute cimv2/root/dcim/DCIM_LCService
