3 1 Introduction This section will give you brief introduction to the NetWatch software. For more detailed information about NetWatch, please refer the release notes and help documents. Eaton NetWatch shutdown agent allows you to connect server or workstation to ConnectUPS SNMP/Web card or NMC based UPS via network connection. The server or workstation on which NetWatch is installed will become a client of the SNMP/WEB adapter or the Network Management Card. The NetWatch client will be notified of power events or UPS alerts. The NetWatch client can be configured to allow only messaging for information purposes, or to begin an orderly shutdown of the client computer to avoid a crash in the event of power failures, which could extend beyond the normal runtime of the UPS batteries. VMware ESXi does not have administrative console for hypervisor and hence we cannot install Netwatch shutdown agent on hypervisor system. However we can install Netwatch on VMware Infrastructure Management Assistant(VIMA 1.0) or on vsphere Management Assistant(vMA 4.0) to manage shutdown of the VMware ESXi in case of Ups and/or power anomalies. We can also configure ESXi to safely suspend or shutdown guest operating system by properly configuring ESXi hypervisor. This way we can have only one NetWatch shutdown agent on one guest operating system(vima/vma). There are various benefits to Installing NetWatch client on the VIMA/vMA instead of each client machine: Only one binary of NetWatch client on the one guest machine to manage all virtual machines. Dynamic management of virtual machines configuration with a personalized script. This guide will help to install and configure NetWatch client on VIMA/vMA. NetWatch client is tested on VMware virtualization server with four guest operating systems for electrical power events, shutdown, low battery and reboot.

4 2 Installation This guide provides information about installing and configuring NetWatch client on VIMA or vma. These recommendations will guide you through the installation process of NetWatch as a shutdown agent for VMware ESXi architecture to allow electric continuity. 2.1 Prerequisites The following are prerequisites: 1. VMware ESXi Server Machine 2. VMware Infrastructure Management Assistant VIMA 1.0 or on vsphere Management Assistant(vMA 4.0) installed as guest. 3. VMware Infrastructure client installed on different machine to VMware ESXi Server configuration. 4. NetWatch 5.0 Installer 5. SSH client like putty for installation and configuration 6. SCP Client like WinSCP to upload packages to VMware ESXi server VIMA/vMA installation Please visit for more information about download and installation of VIMA or vma on ESX/ESXi host machines VMware ESXi Server configuration For the automatic OS boot on startup: you must configure the physical machine to allow automatic OS boot on startup. This setting is present in your machine s BIOS. For further information, see specific technical hardware documentation. To allow interactions between physical and virtual machines, VMware tools have to be installed on each virtual machine. For further information, see VMware ESXi Server documentation. You can configure the automatic startup and shutdown properties of guest operating systems as suspended. But to work Netwatch properly VIMA/vMA needs to configure as o Automatic Shutdown of guest(vima/vma) when ESXi host is going down and o Automatic Startup of guest(vima/vma) when ESXi host is starting Following procedure will explain about configuration of VIMA/vMA shutdown and startup properties From the Virtual Infrastructure Client interface select topmost item ESXi host server from left hand side tree hierarchy, go in the Eaton NetWatch on VMware Installation Guide Page 4/10

window will appear on screen, Select VIMA/vMA guest machine and click on edit button and configure as shown

5 1. Select Configuration tab 2. Select Virtual machine startup / shutdown menu -> Click Properties present in right hand corner Following window will appear on screen, Select VIMA/vMA guest machine and click on edit button and configure as shown above Startup Settings Click Use specified settings Startup Delay 10 Seconds Shutdown Settings Click Use specified settings Shutdown delay 30 seconds Eaton NetWatch on VMware Installation Guide Page 5/10

For the automatic boot of guest machines on VMware ESXi on start-up: From the Virtual Infrastructure Client interface, go in the Virtual machine startup / shutdown menu Configuration Properties Start

6 For the automatic boot of guest machines on VMware ESXi on start-up: From the Virtual Infrastructure Client interface, go in the Virtual machine startup / shutdown menu Configuration Properties Start and stop VMs with the system, and tick enable. Note: In the «Properties» page, you also have the possibility to define the Startup Order of your virtual Machines. Start and Stop VMs with the system : Enabled Default Startup Delay : x Seconds Default Shutdown Delay : x Seconds Startup Order : Automatic Startup This configuration is illustrated on the following screenshot: Network architecture All hardware elements must have an operational network configuration that allows them to dialog freely with each other. NetWatch client use UDP for communication with UPS. Please make sure that following UDP ports need to be enabled on VIMA/vMA Firewall For Eaton UPSs from the Powerware series, open ports 2844, 2845 if you want to go with default Eaton Port or Port. For more information see the Advanced Port Setting option in NetWatch help file For Eaton UPSs from the MGE Office Protection Systems family, UPS Connections on udp port 4679 and 4680 need to be to open for NetWatch communication with UPS Example: For NMC Cards sudo iptables -I INPUT -p udp --dport j ACCEPT sudo iptables -I INPUT -p udp --dport j ACCEPT sudo iptables -I OUTPUT -p udp --dport j ACCEPT sudo iptables -I OUTPUT -p udp --dport j ACCEPT For ConnectUPS SNMP Cards sudo iptables -I INPUT -p udp --dport j ACCEPT Eaton NetWatch on VMware Installation Guide Page 6/10

7 sudo iptables -I INPUT -p udp --dport j ACCEPT sudo iptables -I OUTPUT -p udp --dport j ACCEPT sudo iptables -I OUTPUT -p udp --dport j ACCEPT After this save the iptables configuration by running following command sudo service iptables save To configure your VMware ESXi Server for the network, please refer to the VMWare ESXi user manual. 2.2 Installation of Netwatch on VIMA/vMA VIMA/vMA configuration You can get more information about configuration of VIMA or vma at, To install Netwatch on VIMA/vMA needs administrative privilege of VIMA/vMA Transfer Netwatch tar file to VIMA/vMA machine using ssh or download it using ftp. Before installing Netwatch VIMA/vMA machines needs to be configured for target servers. For more information about adding target servers, refer Adding Target Servers to VIMA present in VIMA user guide. Command to add target server is sudo vifp addserver <servername> it will ask to root password of target server. After that we need initialize vi fastpass for use of Netwatch scripts on the target server, as follows sudo vifpinit <servername> Now you can start Netwatch installation on VIMA/vMA. Following steps will guide you to install and configure Netwatch on VIMA/vMA Netwatch Installation The following steps will explain about obtaining the latest version of NetWatch from the Eaton Web site. Installation and provide information about the shutdown script. 1. For more information about VIMA/vMA please visit 2.

If you want more Netwatch configuration options by following command a. Go to Netwatch directory and run sudo./netwatch -h Netwatch configuration for VMware ESXi To shutdown ESX/ESXi servers from VIMA/vMA needs to provide server list of ESXi servers. To update server list please follow the following procedure. 1. Go to Netwatch installation directory(eg /usr/powerware/netwatch/) 2. Update VMwareESXHosts to add ESXi host server list sudo vi VMwareESXHosts Add all ESXi server hostbane separated by space. Please note to add ESXi server on which VIMA/vMA is installed to be at the last of the entry. Like example below ESXi.linxserverHost1.com here in above we have added 3 servers to manage by Netwatch and is the VIMA/vMA guest operating system on which Netwatch is installed.
