How to upgrade from Airwave 7.6.4 to Airwave 7.7.1
******Attention******** We have an N+1 Design 

	a) master.xxx.com  -> This Airwave instance is our Master and installed in Master DC
	b) failover.xxx.com  -> This Airwave instance is our Failover applicance which is backing up Master Data every Night

	Both instances have to run the same firmware so when we upgrade Airwave the secuence has to start first with the FR unit and then with the Master.After Upgrade Failover unit, we
	need to disable the amp to avoid the automatic failover and when the upgrade has been completed on the Master, you will have to enable amp. Remember the following commands will
	be applied on the Failover unit


	# root
	# amp_disable     ---------> To disable the amp service until Master is upgraded
	# amp_enable	  ---------> To enable the amp service again


 	If the comunication between both servers is broken so due, Failover Server will lose his License and will become Master and it is necessary load the failover
	licenses manually. Below you have the details to re-activate Filover.

 

This manual assume that your CENT OS is version 6 and not early version. Also you have to upgarde the Failover server first and follow the same proccess for the Master Server

Early versions of Cent OS is not supported in airwave 7.7.1



1) First you need to download the upgrade package 7.7.1 from the support site 
   http://support.arubanetworks.com/DOWNLOADSOFTWARE/tabid/75/DMXModule/510/Default.aspx?EntryId=4818

2) After doing that we need to download a program that let us send that upgrade packiage into the airwave server
   The program name is WinSCP
   Site where you can download it http://winscp.net/eng/index.php or from Sharepoint http://internal.varian.com/corp/vit/NTS/Wireless%2020/Forms/AllItems.aspx?RootFolder=%2Fcorp%2Fvit%2FNTS%2FWireless%2020%2FTools&FolderCTID=0x0120001707C14C9C636D4DABA2327DEDA4EF26&View={35C60E6E-B24C-4B6A-AD62-454308388E14}

3) You Installation WinSCP package

4) Log in by SSH to the airwave

   # cd /root

   # mkdir upgrades                (upload upgrade packages into /root/upgrades/)

5) Open a SCP session with WinSCP client to the Airwave Server and enter root as user and the desiganted password 

6) Upload the new pagkage to /root/upgrades/

7) After you have copied the file then we need to log by SSH to the airwave
 
8) Execute the command start_amp_upgrade -f /root/upgrades -v 7.7.1 and wait about 10 minutes

9) In case you received a warning message at the end of the upgarde proccess to upgarde the kernel like:

	***************************************************************
	Updated kernel packages that fix various security issues are now
	available for your OS. To upgrade, run the command below and
	reboot your system.

	  cd /root/svn/mercury/src/x86_64/rpms/CentOS-6; rpm -Uvh kernel-2.6.32-358.18.1.el6.x86_64.rpm kernel-headers-2.6.32-358.18.1.el6.x86_64.rpm kernel-firmware-2.6.32-358.18.1.el6.noarch.rpm

	For more information refer to the security advisory:
	  http://rhn.redhat.com/errata/RHSA-2013-1173.html

	***************************************************************

    Then, you have to upgarde kernel as peer instrucctions below:
	# cd /root/svn/mercury/src/x86_64/rpms/CentOS-6; rpm -Uvh kernel-2.6.32-358.18.1.el6.x86_64.rpm kernel-headers-2.6.32-358.18.1.el6.x86_64.rpm kernel-firmware-2.6.32-358.18.1.el6.noarch.rpm
	Preparing...                ########################################### [100%]
	   1:kernel-firmware        ########################################### [ 33%]
	   2:kernel                 ########################################### [ 67%]
	   3:kernel-headers         ########################################### [100%]
	# reboot


Then reboot Server

9) After that you need to reboot  executing this command

   shutdown -r now 

10) Wait few minuntes after the server has been totally rebooted and log viw web to verify the new version is running properly
