Goal

 

 On new hardware, ibswitches do no longer show FQDN (Fully Qualified Domain Name)

Switch  : 0x0010e035b956a0a0 ports 36 "SUN DCS 36P QDR sw-ib1 10.6.139.59" enhanced port 0 lid 3 lmc 0
Switch  : 0x0010e035b84da0a0 ports 36 "SUN DCS 36P QDR sw-ib3 10.6.139.61" enhanced port 0 lid 1 lmc 0
Switch  : 0x0010e035c10ba0a0 ports 36 "SUN DCS 36P QDR sw-ib2 10.6.139.60" enhanced port 0 lid 2 lmc 0


While uname -a from the switch, shows as fully qualified

# uname -a
Linux x17psw-ib1.svr.us.company.net 2.6.27.13-nm2 #1 SMP Thu Feb 5 20:25:23 CET 2009 i686 i686 i386 GNU/Linux

This is different from other installation at the same site, which show FQDN

 

# ibswitches
Switch  : 0x002128f57308a0a0 ports 36 "SUN DCS 36P QDR sw-ib1.svr.emea.company.net" enhanced port 0 lid 2 lmc 0
Switch  : 0x002128f57334a0a0 ports 36 "SUN DCS 36P QDR sw-ib2.svr.emea.company.net" enhanced port 0 lid 3 lmc 0
Switch  : 0x002128f5734ba0a0 ports 36 "SUN DCS 36P QDR sw-ib3.svr.emea.company.net" enhanced port 0 lid 1 lmc 0

 

The following files are set up correctly:

cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
10.6.139.117    sw-ib1.svr.us.company.net  x18tsw-ib1


# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=sw-ib1.svr.us.company.net
