Re: [xcat-user] "Unrecognized directive" during auto-discovery.

Thu, 28 Mar 2013 13:34:50 -0700

I use FQDN with xcat. I think this was the only change:

sbin/xcatd:
    my $validclient=0;
    my $node;
    foreach my $client (@clients) {
        #$client =~ s/\..*//;  <-- don't strip off domainnames
        ($node) = noderange($client); #ensure this is coming from a node IP at least
        if ($node) {  #Means the source isn't a valid deal...

At this time we do not support fqdn host names in the xcat tables.  That is future development.

If the node name in the xcat tables is changed from the short name, to the fqdn (labcm0005.nyc.desres.deshaw.com), the “unrecognized directive” and “dhclient” messages disappear from the console, but the looping otherwise continues.   See below for corresponding output..
 
I wonder if xcatdebug can be used to pinpoint the problem?   I tried running it with call trace and comments enabled, but it produced so much information it’s hard to spot  what’s significant.    
 
Thanks

Subject: "Unrecognized directive" during auto-discovery.
 
 
Discovery appears to work, the mac is discovered, the DHCP entry is created, and the genesis dhclient gets the new MAC address, but then it keeps looping in discovery, with the console displaying an “unrecognized directive <error>unknown” message.   If I run: “chdef labcm0005 curstate=<some state other than discover>”, then discovery ends.   The only thing that’s changed is that since 2.8.0, whe’re no longer using “nodeset host discover”, but setting the chain manually.
 
Thanks
 
Details:
 
We used to be able to run the following to initiate node discovery before 2.8.0:
 
rmnodecfg host
nodeset host discover
 
(BTW: the rmnodecfg should delete the dhcp entry BEFORE deleting the MAC address from the xCAT table.   Here’s a diff to make it work.)
[root@drdkvm0003 bin]# diff rmnodecfg.old rmnodecfg.new
33c33
<   $cmd = "chtab -d node=$blade mac";
---
>   $cmd = "makedhcp -d $blade";
36c36
<   $cmd = "makedhcp -d $blade";
---
>   $cmd = "chtab -d node=$blade mac";
 
Now “nodeset … discover” provides the error:
 
[root@drdkvm0003 xcat]# nodeset labcm0005 discover
Error: Unknown state discover requested
 
If the chain is set up manually as follows, discovery starts to happen, and seems to work, but never ends:
 
[root@drdkvm0003 xcat]# chdef labcm0005 chain="discover,runcmd=bmcsetup,install,boot" _ondiscover_=nodediscover
 
The  discovery process initiates, the node gets a dynamic address and communicates back, the mac address is discovered, a correct DHCP lease is created, and it gets its assigned IP and hostname (not dynamic.).   However it never recognizes that discovery was successful and complains about “Unrecognised directive”
 
Here’s the console output:
