Thank you, Yuan and Christian!
I have actually pretty much done what both of you had suggested, and it
does work - somewhat.
I have the following networks:
[root@hpcmn-test ~]# tabdump networks
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,mtu,comments,disable
"hpcpublic","192.168.20.0","255.255.255.0","eth1","192.168.20.1",,,,,,,,,,,,"
sabre.kkeane.sandiego.edu","1500","HPC Public Network",
"hpccompute","192.168.100.0","255.255.255.0","eth0",,"192.168.100.2","<xcatmaster>",,,,"192.168.100.200-192.168.100.229",,,"/z/-compute/",,,"
compute.sabre.kkeane.sandiego.edu","1500","HPC Compute Network",
"hpcmanagement","192.168.101.0","255.255.255.0","eth2","<xcatmaster>","192.168.101.2","<xcatmaster>",,,,"192.168.101.200-192.168.101.229",,,"/z/-imm/",,,"
imm.sabre.kkeane.sandiego.edu","1500","HPC Management Network",
I also have defined hpcmn-test as a node (thanks, Christian, for the tip
about unmanaged!):
Object name: hpcmn-test
groups=all
hostnames=hpcmn-test.kkeane.sandiego.edu
hpcmn-test.imm.sabre.kkeane.sandiego.edu
ip=192.168.101.2
postbootscripts=otherpkgs
postscripts=syslog,remoteshell,syncfiles
When I manually edit /etc/hosts as Yuan suggested, everything does work:
127.0.0.1 localhost
192.168.101.2 hpcmn-test hpcmn-test.imm.sabre.kkeane.sandiego.edu
hpcmn-test.kkeane.sandiego.edu.
But there are two problems with this:
- hpcmn-test.kkeane.sandiego.edu really should be associated with the
public IP (192.168.20.2 in my example)
- makehosts does not honor this name, even though it is in the node's
hostnames attribute. Here is what makehosts produces:
127.0.0.1 localhost
192.168.101.2 hpcmn-test hpcmn-test.imm.sabre.kkeane.sandiego.edu
