Hi all,
Our network setup is like so:
- 1Gb ethernet (deployment / xCAT / management network)
- 10Gb ethernet
- out-of-band (IMM/BMC)
Right now, our DNS is handled by setting up search paths on our xcat
server (via /etc/resolv.conf), with the *fastest* paths being resolved first.
So, 10Gb is resolved before 1Gb, like such:
$ cat /etc/resolv.conf
nameserver 10.230.16.5
nameserver 10.230.16.6
search fst.domain.com mcp.domain.com lom.domain.com i2b.domain.com domain.com
$ host testcoreb
testcoreb.fst.domain.com has address 10.233.1.68
$ host testcoreb.mcp
testcoreb.mcp.domain.com has address 10.230.1.68
10.233 is 10Gb ethernet, and 10.230 is 1Gb ethernet. We DO NOT want to
provision/manage (psh, etc) over 10Gb, but rather the 1G ethernet. We don't use
slashes in our short hostnames (hostname-mgmt), which I think is causing a
problem. Some hosts that do not have a 10GbE provision fine, because the short
name lookup defaults to that node's 10.230 network, which is correct:
$ host fsm07
fsm07.mcp.domain.com has address 10.230.1.87
We only have dhcpd listening on 1Gb ethernet as well:
$ tabdump site | grep dhcp
"dhcpinterfaces","eth0",,
When I do a nodeset testcoreb osimage=imageName, the 10.233 interface is used,
which is wrong:
kcmdline=quiet repo=http://10.233.1.5:80/install/rhels6.4/x86_64
ks=http://10.233.1.5:80/install/autoinst/testcoreb.mcp
ksdevice=40:f2:e9:0c:ef:04 cmdline console=tty0 console=ttyS19200,hard
>From dhcpd.leases:
host testcoreb {
dynamic;
hardware ethernet 40:f2:e9:0c:ef:04;
fixed-address 10.233.1.68;
supersede server.ddns-hostname = "testcoreb";
<SNIPPED>
Is there a way to explicitly tell xCAT *not* to do a DNS lookup for the
shortname, and determine which interface to set for the tftp server? I've tried
the following in the noders table, without any success:
$ tabdump noderes | grep testcoreb
"testcoreb",,"pxe","10.230.1.5",,"10.230.1.5","10.230.1.5",,"mac","mac",,,,,,,,,
I've tried manually setting all of this in the bootparam table, etc, without
any success.
So, why long-winded question is, am I just missing setting a key somewhere in
one of the 40+ xCAT tables to override the short name lookups, and explicitly
use the 1Gb ethernet network? I haven't even defined the 10Gb ethernet network
in the xCAT networks table either…
Thanks,
~Steve
