About predefined computers in Deployment Solution

Deployment Solution

Predefined computers in Deployment Solution are computers, the details of which, such as the computer name and MAC address are added even before the computer is connected in the network. You can specify the name, computer details, and hardware identifiers of a computer that you want to resolve as a predefined computer. You specify the computer name and other details through the SMP console to add a computer as a predefined computer.

Deployment Solution lets you either add the predefined computer details or import the list of computer details through the SMP console. You import the predefined computer details through a TEXT (.txt) or CSV (comma-separated values) file. Both addition or import of predefined computer details can be performed through the Settings > Deployment > Predefined Computers dialog box of the console.

To create predefined computer entries through the Settings > Deployment > Predefined Computers dialog box of the console, you must specify a name. The name is a mandatory field to create predefined computer entries in Deployment Solution.Besides, name, you can choose to specify the other details such as computer details and hardware identifier details. The hardware identifier entries, although not mandatory, play an important role in discovering computer of a network as a predefined computer.

If an unknown computer is discovered in a network, Deployment Solution boots the computer with a PXE image that you configure for unknown computers. PXE images are configured through the NBS General Settings dialog box of the console. Before the discovery process, if you have specified entries for predefined computers through the Predefined Computers dialog box, then the specified hardware identifier entries are matched with that of the booting computer. Entries of hardware identifiers such as MAC, SerialNumber, and UUID are matched with those of the booting computer. Based on the matching results, you configure the unknown computer as a predefined computer.

Deployment Solution resolves an unknown computer as a predefined computer based on the following matching criteria:

  • If the values for the hardware identifiers, MAC, SerialNumber, and UUID are specified as null in the Predefined Computers dialog box.

    In this case, all the unknown computers that are discovered are potential predefined computers of Deployment Solution. For example, if you do not specify any value for MAC, SerialNumber, and UUID fields in the Predefined Computers dialog box, then all unknown computers are identified as potential predefined computers. In this case, the unknown computer boots with the PXE image that is configured for the predefined computers through the NBS General Settings.

  • If one or more values of the hardware identifiers, MAC, SerialNumber, and UUID matches with that of the booting computer.

    In this case, based on the number of hardware identifiers whose values match, the booting computer is identified as a predefined computer. The booting computer whose two or more values match have the highest potential to be a predefined computer. For example, you specify value for MAC as M1 and the values for the identifiers as null , then if booting computer's MAC is M1, this computer has good possibility to be a predefined computer. If two specified identifier values match, for example, MAC as M1 and UUID as 1234 with that of the booting computer, then this computer has higher possibility to be a predefined computer over other computers.

  • If the hardware identifier values that you specify matches with that of the booting computer then the computer boots with the PXE image that you configured for predefined computers.
