in command mode type

#set_parms hostname

then you will prompt to change your hostname. after changing hostname the system must be rebooted for change effect.

/etc/hosts, DNS server data, NFS server
sharing data, .rhosts, /etc/hosts.equiv, and
so on (and on). How many places did you use
the old name?

nothing new from my side.

#sep_parms hostname

update "/etc/hosts" or DNS entry if u r using DNS.

check entry in /etc/rc.config.d/netconf for changed hostname.

if u have configured rlogin then change this .rhosts on other hosts where entry for this hosts exist.This is also applicable in case of cluster.

apart from this u can also change /etc/cmcluster/nodenmae file.

how to make sure that hostnam eis changed?:
run "hostname" command

You can change it in /etc/hosts file

&

/etc/rc.config.d/netconf file.

Note- Dont take the backup of netconf file in the same directory.

Thanks,

Dear Rkumar

if u want to change the hostname of the u host itself u have to use set_parms command,
effect will be next reboot onwards.
if u want to change the hostnames of otherhosts
u have to edit /etc/rc.config.d/netconf file and /etc/hosts file

thanks and regards

Hi Rkumar,

Apart from set_parms command you can use SAM also to change the host name.
