1.1. DESCRIPTION

The VIRTUAL JNC is software for automatically managing the shutdown of virtual machines and hosts in the VMware® environment.

It includes an intuitive graphical interface and ensures an ordered shutdown process for all Virtual Machines.

The VIRTUAL JNC contains two software programs:

• JNV Service Configuration

- Network configuration (UPS IP address – port settings)

- Virtual Machine automatic discovering service

- Delay and shutdown parameters for each Virtual Machine and Host(s)

• JNV Service Viewer

- UPS Status

- Shutdown process notification

The shutdown agent is managed as a WINDOWS service.

The UPS which supplies the server must be equipped with a WEB/SNMP (i.e. NetVision) interface and shutdown events and timings

must be configured via the web pages.

1.2. COMPATIBILITY

VIRTUAL JNC is a .Net application for MICROSOFT WINDOWS™. Before installing the software make sure the latest version of .Net

framework has already been installed (v 4.0 full or higher).

1.3. REQUIREMENTS - RECOMMENDED INSTALLATION

This manual does not explain VMware® SW functionality. The VIRTUAL JNC uses native API libraries of VMware®.

It is advisable to install the VIRTUAL JNC on a MS Windows VMware vCenter™ server (Virtual Machine or external PC). To perform

the shutdown correctly VMware tools must be installed and updated on all virtual machines. If these tools are not present the shut-

down agent will force a POWER OFF command on the VM.

1.4. GLOSSARY OF TERMS

Host: Physical server

VM: Virtual Machine

SD: Shutdown

JNV: Name of VIRTUAL JNC shutdown agent program

JNV server: Defined as the VM, vCenterVM or external PC where the VIRTUAL JNC SW is installed.

JNVVM: Virtual Machine where the JNV agent is installed.

JNVHost: ESXi host where the JNV is installed.

vCenterServer: Defined as the physical external server where the VMware vCenter™ is installed.

vCenterVM: Virtual Machine containing the vCenter SW

vCenterHost: ESXi host server containing the vCenterVM

Clusters: Multiple Host VMware® environment

1. INTRODUCTION

The JNV is compliant with all SOCOMEC UPS network interfaces.

- NET VISION

- RT VISION (Integrated SNMP/LAN interface board)

- MODULYS Green Power embedded LAN connection

- DELPHYS Green Power mimic panel

2.1. SHUTDOWN CONFIGURATION

See the user manual for your UPS and WEB/SNMP interface.

2.2. REDUNDANT N+1 INDEPENDENT UPS ARCHITECTURE

JNV is compliant with N+1 UPS architecture. JNV enables the possibility of selecting UPSs with or without redundancy.

In the case of redundant architecture the JNV agent waits for all UPS requests before performing the VM shutdown process. If not

redundant, the first UPS event initiates the shutdown process.

In this specific case UPSs have to be configured as a parallel system (up to 6 UPS) on JNV agent. Each UPS has its own IP address.

2. UPS NETWORK CONNECTION


For more details on the VMware® environment and tools please refer to the website. (www.vmware.com)

3.1. ESX COMPATIBILITY

Virtual System Version Notes

VMware FREE LICENSE NOT SUPPORTED

VMware with vCenter ESX®/ESXi™ 3.5

VMware with vCenter ESX®/ESXi™ 4.1

VMware vSphere with vCenter ESXi™ 5.0

VMware vSphere with vCenter ESXi™ 5.5

3.2. VCENTER COMPATIBILITY

It is strongly recommended to install the JNV software on the MS Windows VMware vCenter™ server. The vCenter can be installed

on a VM or external server.

JNV is incompatible with the VMware VCenter™ version on LINUX.

If there is no VMware vCenter™ the JNV must be installed on a MS Windows VM.

3.3. VMWARE TOOLS

VMware tools must be installed on all virtual machines. If VMware Tools are not installed the JNV sends a POWER OFF command

instead of an OS shutdown execution.

3.4. VM UUID MANAGEMENT

Thanks to the vCenter server the JNV discovers all VMs from all hosts. VM UUIDs are stored in a database (external XML file). When

one VM is moved to another host using H.A.1 or vMotion technology, it is not necessary to change the JNV shutdown parameters

for this VM.

This functionality is not available if the vCenter is not present. In this case it is necessary to modify the VM parameters manually.

4.2. JNV INSTALLATION POSSIBILITIES

Case 1: VCenter not present

In this case VIRTUAL-JNC must be installed on a windows VM for each ESX server (1 VIRTUAL-JNC licence required for each

installation). If there is only one ESX server it is also possible to install VIRTUAL-JNC on an external PC/server that belongs to the

same subnetwork as the ESX server.

Case 2: VCenter present and installed on a virtual machine

In this case VIRTUAL-JNC must be installed on the virtual machine on which VCenter is installed

Case 3: VCenter present and installed on an external PC/server

In this case VIRTUAL-JNC must be installed on the external PC/server on which VCenter is installed. The external PC/server in

question must be on the same subnetwork as the ESX server.

country flag.

5.1. INFORMATION SLIDE: UPS AND NETWORK CONFIGURATION

Parallel modules

Enter the number of UPS units in parallel supplying power to the Hosts protected by VIRTUAL-JNC.

If there is only one UPS, enter 1.

Examples:

CASE 1: for a single UPS set 1;

CASE 2: for UPS units in parallel equipped with a single Ethernet Network Interface, set 1;

CASE 3: for an independent UPS system, set the number required.

CASE 1 CASE 2 CASE 3

Single UPS UPSs in parallel

with shared LAN connection

Independent UPS

with dedicated LAN connection

5. VIRTUAL JNC CONFIGURATION


Redundancy

To be set only if the number of UPS units is >1.

Redundancy=NO means non-redundant system. In this instance, VIRTUAL-JNC starts the shutdown procedure when any single

UPS unit in the parallel system detects a shutdown event (e.g. UPS Failure).

Redundancy=YES means n+1 level redundant system. In this instance, VIRTUAL-JNC starts the shutdown procedure only when at

least 2 UPS units in the parallel system simultaneously detect a shutdown event (e.g. UPS Failure).

Address:

Enter the IP address of the UPS Ethernet Network Interface (IPv4 only)

Remote Server UDP port:

200 by default, it should be the same port used by the UPS Ethernet network interface.

When a new parameter is set it must be saved . The JNV service stops and starts automatically after saving parameters.

Using and starts and stops the service manually.

When the service starts, communication between the JNV and UPS Ethernet Network Interface is established.

If the JNV viewer is running, and the connection is established, a message appears in the service area and the UPS icons turn green.

VM DEFAULT GROUP AND HOST(S) CONTROL

Add new VM to group:

If a VM is added after this configuration stage, the VM is added in the group selected in this drop down list.

Ordered group: shuts down the VM in a specific order and after a specific delay.

Any Order Group: shuts down all VMs at the same time.

There is also a Shutdown with hosts group. In this case the shutdown of these VMs is not managed from JNV. It will switch off

when Hosts shut down according to the specific host settings.

Perform host power off:

if this option is selected the host will be POWERED OFF when all VMs are down. If there is more than one all hosts will be powered

off at the same time.

Note: If the JNV is installed on a VM on this host, it will power off after 10 s with respect to the other hosts. Check the JNV

conditions (also with different hosts).



SHUTDOWN PROCESS CONTROL

Script to execute:

It is possible to execute a script or batch file when the JNV agent receives the shutdown command from the UPS. This script is

executed wherever the JNV is installed, on a VM or vcenterVM, or vCenter server.

If this field is blank no action will be executed.

Process starts in:

Specifies the time in seconds when the shutdown process will start. The countdown starts when the JNV agent receives the

shutdown command from the UPS (irreversible phase).

When the delay is reached the shutdown command is sent to the first VM in the Ordered Group.

JNV server name:

Identifies the name of the JNV Server. This name is displayed in the client list of the UPS WEB/SNMP interface.

Example of NET VISION client table:

Shutdown JNV server (cases with vCenter server present):

JNV Server means the VM, vCenterVM or external PC where the VIRTUAL JNC SW is installed.

This function behaves differently depending on where the JNV is installed.

5.3. VIRTUAL MACHINES LIST VIEW

VIRTUAL MACHINE INTERFACE

The table shows the 3 groups of VMs. For VM in ordered group the table gives the type of delay management and its value.

It is also possible to change VM from one group to another using the UP and DOWN buttons.

DISCOVERY OF VM MACHINES

When this window is open VMs are automatically updated.

updates the list in the case of VM changes on the host. This function is disabled during JNV setup. It is necessary to save the

configuration ( ) before requesting VM discovery.

ORDERED GROUP

VMs present in this group will be shut down following the list order. Shutdown of the next VM is dependent on the delay condition

relative to the previous VM.

Shutdown sequence:

1 The first VM shuts down when the shutdown process countdown is reached (shutdown parameters configuration tab).

2 Shutdown of the second VM is performed when the first one is off (SkipOnPowerOff) or at the end of the delay interval (WaitFull).

3 , The next VM follows the same principle.


EN

GL

ISH

EN

GL

ISH


DELAY CONDITIONS FUNCTION

Skip on Power Off

Once one VM is off, the next VM starts shutting down.

If at the end of the delay the VM is still on, the JNV forces a POWER OFF command to this VM and sends a shutdown command

to the next VM.

POWER OFF (1)

Time delay

Next VM shutdown

Wait Full Delay

The next VM shuts down at the end of the delay even if the current VM is shut down. If this VM is not powered off at the end of this

delay JNV forces a POWER OFF command and shuts down the next VM.

POWER OFF (1)

Time delay

VM shutdown time

Next VM shutdown

(1) forced if the shutodwn does not occur in the VM time delay.

ANY ORDER GROUP

JNV sends a shutdown command to all VMs in this list when the last VM of Ordered Group is down or powered off.

After 1 minute (timeout) JNV sends a power off command to the VMs that are still running. JNV still waits for all the VMs to be correctly

shut down by the shutdown command during this timeout interval.

SHUTDOWN WITH HOST GROUP

JNV ignores all VMs in this list.

The VMs located in this group will be shut down only in the case where a Host PowerOff (where the VMs are running) is performed.

Shutdown conditions and configurations are independant of JNV and may need to be configured manually on the host settings.

VM POSITION MODIFICATION

and moves the selected VM in the list. Use to change the first of Any

Order Group to the last VM of Ordered Group.

VM SHUTDOWN DELAY MODIFICATION

Select a VM from Ordered Group, change the delay management and its value, then to confirm the change.

The VM in the Ordered group is updated. Do not forget to save the change.



5.4. SHUTDOWN DELAY MANAGEMENT

Example:

Shutdown with hosts

Process timing:

The VM win2003std64en01 is the first VM to to be shutdown in this example.

The VMs from Any Order group, CSWDevelop and openSUSE VMs shut down when the VM Solaris10 is off.

The VMs from Shutdown with hosts group are not shutdown by the JNV software.

Timing data:

1. The maximum duration of shutdown sequence for Ordered group - calculation based on this formula:

∑ of time lags for each VM ; 3 * 15 = 45 seconds max.

2. The duration of the shutdown sequence for the Any Order group is limited to 60s (1 min).

3. Add a time lag of xx seconds before launching the process and a 90s time lag before shutdown of the hosts.

4. Total time for shutdown process:

xx + 45 + 60 + 90 = xx + 195 s

Restriction:

- It is not possible to execute a local script on the VM or host.

- If VMware tools are not operating on each VM, the POWER OFF command is executed instead of an OS shutdown command.

5.5. BATTERY BACKUP TIME MANAGEMENT

NOTE: all delays defined in the shutdown process have to take account of:

- Remaining battery backup time

- Time needed to shut down all VMs and hosts.

Total time of VM SD process (worst case):

∑ VM delay (order group) + 60s of timeout (Any Order Group) + 90s for JNV server shutdown

Total of SD process:

UPS shutdown delay + JNV countdown + VM SD process.

For security reasons it is suggested that:

Total of SD process <= ½ Battery backup time

Example with 10’ of backup time (600’’), host with 9 VM + VM where JNV is installed

Parameters Delay (example) Number Process time

Local delay ('Process Starts in' parameter) 20" (set by configuration) 1 20"

Delay of VM SD (ordered group) 20" (set by configuration) 9 180"

Timeout for Any Order Group 60" fixed delay 1 60"

Host SD (only if perform host power off is enabled) From 30" to 90" 1 90"

TOTAL 350"

For compliance with the safety margins (1/2 battery back-up time), it is recommended that the UPS runs on the battery for 1 or 2

minutes at the most before sending the shutdown command to the server.

If the UPS shutoff is configured by the Ethernet Network Interface, it is necessary to check the delay according to

the complete shutdown time needed.
