Things to do when you rename a host for lease return.

You must be concerned if you move to a new hardware that you get a new
veritas license.

In this example, HOSTNAME and HOSTNAME-new change places 
	(HOSTNAME-new becomes HOSTNAME, HOSTNAME becomes HOSTNAME-old).

Check to make sure /usr/local/* is setup with needed files.

If cluster node
   hastop -all

   on one cluster node
       vi /etc/VRTSvcs/conf/config/main.cf

   on other cluster nodes
       mv /etc/VRTSvcs/conf/config/main.cf \
       	  /etc/VRTSvcs/conf/config/old_main.cf \

On HOSTNAME-new
	vi /etc/nodename	#change to HOSTNAME
	vi /etc/hosts		#change to HOSTNAME and change IP
	vi /etc/netmasks	#make sure it is correct
	vi /etc/defaultrouter	#make sure it is correct
	vi /etc/defaultdomain	#make sure it is correct
	vi /etc/hostname.[le,eri,hme,ge]0	#change to HOSTNAME
	vi /etc/dumpadm.conf	#change to HOSTNAME
	cd /var/crash; mv HOSTNAME-new HOSTNAME
	# the following edits 3 files
	vi /etc/net/*/hosts	#change to HOSTNAME, use :w to write, :n to goto next file
	vi /etc/inet/ipnodes	#if there and has hostname
	vi /usr/openv/netbackup/bp.conf   #change hostname
  if VCS
  		vi /etc/VRTSvcs/conf/sysname
  		vi /etc/VRTSvcs/conf/config/main.cf
		vi /etc/llttab
		vi /etc/llthosts
	mv /var/crash/HOSTNAME-new /var/crash/HOSTNAME
	make note in web tool #state the date your moving node into production

-Sync cron files - pay attention to: remote and any other non system cron file, otherwise you can ignore differences - but check ROOT anyhow, ignore lp 
-Sync up /etc/passwd, /etc/shadow
-Sync up /export/home if it is local
-Sync up /etc/mail/aliases if mailserver
-Sync up /etc/nis if NISserver
-Sync up /var/named if DNS

Fix lp printers configs: see the jetadmin.faq on moving queues

Do the exact opposite on HOSTNAME
	vi /etc/nodename	#change to HOSTNAME-old
	vi /etc/hosts		#change to HOSTNAME-old and change IP
	vi /etc/hostname.[le,hme,ge]0	#change to HOSTNAME
	vi /etc/net/*/hosts	#change to HOSTNAME-old, use :w to write, :n to goto next file
	vi /usr/openv/netbackup/bp.conf   #change hostname
	#stop cron - so jobs won't run
	kill -9 `ps -ef | grep cron | grep -v grep | awk '{print $2}'`

Shutdown both nodes
	init 0

Do a vxinstall if needed (depends on scenario)

Log into DNS server and change DNS
	change HOSTNAME-new name entry (and reverse) to HOSTNAME-old
	edit both db.mydomain.com and db.X.X
	restartnamed

-Change netbackup clients if they have changed policies

-Redo any ssh for users that need it.

-Relabel the physical name stickers on hosts.

-Let the network team know of the change for HP OpenView up/down monitoring.
