Goal
How to change hostname on an NM2 infiniband switch?
Fix
Initial hostname: edx28bur09sw-ib2.xyz.com
New hostname:edx28sw-ib2.abc.com
[root@edx28bur09sw-ib2 ~]# uname -a
Linux edx28bur09sw-ib2.xyz.com 2.6.27.13-nm2 #1 SMP Thu Feb 5 20:25:23 CET 2009 i686 i686 i386 GNU/Linux
Edit the /etc/hosts with new hostname and fully qualified domainname: Change edx28bur09sw-ib2.xyz.com to edx28sw-ib2.abc.com
127.0.0.1 localhost.localdomain localhost
10.10.10.222 edx28sw-ib2.abc.com edx28sw-ib2 <---modify this line
::1 localhost6.localdomain6 localhost6
Edit the /etc/sysconfig/network : change edx28bur09sw-ib2.xyz.com to edx28sw-ib2.abc.int
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=edx28bur09sw-ib2.abc.com<----modify this line
Note: Prior to rebooting the switch you should first determine if this switch is running as the SM MASTER by
checking the output of "getmaster". In the following output we can see that another switch named elx22bur09cn01-gw
is running master so a reboot is all that is needed.. If this switch were running Master SubnetManager, then it would
be best to disablesm before rebooting and then enablesm after switch comes up.
IE:
[root@edx28bur09sw-ib2 ~]# getmaster
Local SM enabled and running
20120531 14:46:50 Master SubnetManager on sm lid 1 sm guid 0x2128568c62c0a0 : SUN IB QDR GW switch elx22bur09cn01-gw 10.10.10.89
If edx28bur09sw-ib2 were running Master SM, then disablesm, reboot, enablesm
IE:
[root@edx28bur09sw-ib2 ~]# disablesm <-----use this command
Stopping partitiond daemon. [ OK ]
Stopping IB Subnet Manager.. [ OK ]
#reboot
Now you should now see the new hostname edx28sw-ib2 with fully qualified domain .abc.com in the output of uname -a
[root@edx28sw-ib2 ~]# uname -a
Linux edx28sw-ib2.abc.com 2.6.27.13-nm2 #1 SMP Thu Feb 5 20:25:23 CET 2009 i686 i686 i386 GNU/Linux
re-enable sm using the following command:
[root@edx28sw-ib2 ~]# enablesm
Starting IB Subnet Manager. [ OK ]
Starting partitiond daemon. [ OK ]
[root@edx28sw-ib2 ~]#
