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).

Merge the following directory:
	/usr/local/* 
Watch for newer versions of files to go here if available.  

If VCS
   One node in cluster
       haconf -dump -makero    #not necessary, but good insurance
       hastop -all -force

       vi /etc/VRTSvcs/conf/config/main.cf

       [scp|rcp] /etc/VRTSvcs/conf/config/main.cf \
			OTHERNODES:/etc/VRTSvcs/conf/config/main.cf

   All nodes in cluster
	gabconfig -U
	lltconfig -U

			# you can start LLT,GAB,HA  up manually by running
			# the rc scripts for each of them AFTER all 
			# the VCS files have been edited.
	
  	vi /etc/VRTSvcs/conf/sysname
  	vi /etc/VRTSvcs/conf/config/main.cf
	vi /etc/llttab
	vi /etc/llthosts

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/nsswitch.conf	#make sure it is correct
	vi /etc/resolv.conf	    #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
				# :w to write
				# :n to goto the next file
		/etc/inet/ticlts/hosts
		/etc/inet/ticots/hosts
		/etc/inet/ticotsord/hosts
	vi /etc/inet/ipnodes

	vi /etc/inet/ipnodes	#if there and has hostname
	vi /etc/hosts.allow     #if there and has hostname
	vi /usr/openv/netbackup/bp.conf   #change hostname for backup s/w

	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, 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

Rename console ports

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

-Fix any ssh for users that need it.

-Fix any .rhosts for users that need it.

-Fix NIS: hosts, netgroup, aliases

-Fix any share trusts on NFS servers (unix and or netapp)

-Fix any mail aliases on localhost and relays

-Relabel the physical name stickers on hosts.

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