Description

Hi Guys,

Foreman Proxy running on windows fail to delete previously created reservation. This one exists since 1.5 I believe.

native_ms module.

DHCP 'hostname' option (12) is wrongly enumerated as install_path and marks the record as NON-deletable and throw an exception (FP log):

The test if the record is 'deleteable' is based on 'hostname' and it's done in native_ms.rb 'loadSubnetData' function:

---

            if opts.include? :hostname
              Proxy::DHCP::Reservation.new opts.merge({:deleteable => true})

---

Option assignment is done in dhcp.rb:

Standard = {
:hostname => {:code => 12, :kind => "String" }, # The host's name
:PXEClient => {:code => 60, :kind => "String" }, # Needs to be empty for foreman to function
:nextServer => {:code => 66, :kind => "String" }, # From where we download the pxeboot image via TFTP
:filename => {:code => 67, :kind => "String" } # The pxeboot image
}
SUNW = {
:root_server_ip => {:code => 2, :kind => "IPAddress" }, # 192.168.216.241
:root_server_hostname => {:code => 3, :kind => "String" }, # mediahost
:root_path_name => {:code => 4, :kind => "String" }, # /vol/solgi_5.10/sol10_hw0910/Solaris_10/Tools/Boot

I'm also being effected by this issue. Do we know what version this might be addressed in?

I am also seeing this behavior in the 1.8 release of the smart proxy. My workaround was to just comment out install_path under SUNW.

A possible fix has been merged to the develop branch and should be in 1.10.2 as well when that's released. I'll mark this as feedback as it may resolve the issue - please let us know either way if you're able to test it.
