12.1 Simultaneous Auto-Discovery Methodologies
516
If more than one discovery methodology is used simultaneously, the provisioning server address
517
acquisition sequence is the following:
518
1) Vendor Scope Option
519
2) DNS SRV record
520
3) Default Host A record.
521
The method selected to provision the server determines the appropriate iDRAC6 configuration utility
522
settings (accessible during boot using Ctrl-E).
523
Depending upon the desired environment, the settings can be filled out in a different ways. All settings
524
must contain valid information; the domain name and IP addresses must be accurate for their
525
environment. No setting can be left empty for Auto-Discovery to succeed, with one exception, DCHP
526
Only.
527
If the discovery methodology is DHCP Only and is using the Vendor Scope option with a Specified IP
528
address (port optional), the only setting in the iDRAC Configuration Utility that needs to be populated is
529
the IP4 address DCHP. The Domain Name and Domain Server IP settings do not need to have any
530
information or be enabled.
531
12.2 Using Static IP addresses
532
It is possible to configure iDRAC to use a static IP address and then proceed with Auto-Discovery to set
533
up user credentials. In this case, the Auto-Discovery feature becomes “one-touch” provisioning for the
534
environment. This method might be preferred if the you want to predetermine the locations and fixed IP
535
addresses of their machines. If a static IP address is entered through the BIOS setup and iDRAC
536
configuration screen (11
th
generation servers) or System Setup (12
th
generation servers), and there are
537
no user accounts supplied, the discovery process attempts to locate the provisioning server through
538
DNS. If a user account is supplied, the initial discovery and handshake becomes unnecessary, and the
539
remote console may use these credentials for configuration using WS-Man or remote RACADM.
540
12.3 iDRAC Auto-Discovery Configuration Settings
541
This section covers the seven methods to configure a server based on the network environment using the
542
four discovery implementation alternatives.
543
The iDRAC Configuration Utility(11
th
generation servers) or iDRAC System Settings (12
th
generation
544
servers) settings are dependent on the provisioning method listed for the following items:
545
 Domain Name - On / off / manual
546
 iDRAC Source - DHCP / Specified
547
 DNS Server IP Address - On / off / manual
548
For the Domain Name and DNS Server IP address settings:
549
 On – the field Domain Name from the DHCP or DNS Server from DHCP is set to ON.
550
 Off – the field Domain Name from the DHCP or DNS Server from DHCP is set to OFF.
551
 Manual – the fields are set to OFF, and the user has entered information manually in the other
552
fields.
553
The following settings listed here are only the LAN parameter settings. The iDRAC6 LAN must be
554
enabled; select the Auto-Discovery field, and disable the Root account in the LAN User section in the
555
