NetBackup BMR Linux DHCP Help Request

[Nathan_Kippen]

I'm trying to use BMR on a Linux client.

Info:

Having issues with the client accepting the DHCP reply...

dhcpd.conf on bmr boot server:

ddns-update-style ad-hoc;

## subnet declaration for each interface on box
subnet X.XXX.0.0 netmask 255.255.0.0 {
  #range X.XXX.100.90 X.XXX.100.99;
  range dynamic-bootp X.XXX.100.90 X.XXX.100.99;
  #range dynamic-bootp X.XXX.124.91 X.XXX.124.92;
  option routers X.XXX.0.2;
  #option broadcast-address X.XXX.255.255;
  option subnet-mask 255.255.0.0;
  default-lease-time 21600;
  use-host-decl-names on;
}
host uhilsb02-01D40003 { hardware ethernet 00:50:56:AD:4C:BC; fixed-address X.XXX.0.3; next-server uhilhpvl; filename "/bmr/pxelinux.0"; } # added by Bare Metal Restore

Any ideas why the client doesn't take IP?  Is it the type of DHCP that's not working right? 

Thanks,

Try following configuration mentioned in below note in BMR admin guide for linux dhcp configuration.

Make sure tftp service too is running on bmr boot server. (This will be as bmr prepare to restore worked successfully in your case.)

--------------------

Create a /etc/dhcpd.conf file and configure it to define the networks it serves.
You do not have to define host information; hosts are added and removed as
needed by the BMR software. The following is an example configuration:
log-facility local7;
ddns-update-style none;
ignore unknown-clients;
subnet 10.10.5.0 netmask 255.255.255.0 {
default-lease-time 600;

Installing BMR on UNIX and Linux systems
18
max-lease-time 7200;
option domain-name "example.com";
option broadcast-address 10.10.5.255;
option domain-name-servers 10.10.1.4,10.88.24.5;
option routers 10.10.5.1;
}
To verify the /etc/dhcpd.conf file syntax, restart the daemon and ensure it
starts successfully by running the following command:
/etc/init.d/dhcpd restart.

This fixed it..
