VMware is virtual machine software that provides a virtualized set of hardware (a video adapter, a network adapter, and hard disk adapters) to the guest operating system. VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. In practice, a system administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer, and there resume execution exactly at the point of suspension. VMware's enterprise software hypervisors for servers, VMware ESX and VMware ESXi are bare-metal embedded Hypervisors that run directly on server hardware without requiring an additional underlying operating system.

Can anyone give a real beginners guide into what types of scenario (e.g. physical disaster, user error, hardware failure) the various replication/DR features at both HW and SW level actually save you from?

For arguments sake, say your setup consists of 5 ESXi hosts in a HA cluster - 2 SAN's at different physical offices which do a HW level replication between each, and you also have a backup software that also does some form of replication?

What kind of failure/issue do the 3 levels actually save you from, I need to get it clear why you need all 3 and what different types of disaster each saves you from, esxi HA cluster of hosts, SAN-to-SAN replication, and replication feature at SW level as part of your backup solution.
is there any standard criteria that can be used to assess the current adequacy of your existing backup solution/software, so it can be effectively compared to new products out there, rather than going into auto-renew mode and just renewing the current solution to the latest version of their product? There are so many products on the market it is difficult to know where to start. 95% of the companies servers are virtual powered by ESXi hosts, but the company seems to have upgraded from backup exec for years without any real strategic thought or analysis if anything better is out there for the budget. are there any limitations in terms of backup exec compared to other solutions more geared towards virtual environments/server backups?

I note some vmware targeted solutions also seem to cover both backup and elements of disaster recovery, so would be interested to identify any current solutions in that area that come recommended - I am sure there must be great variety in costs based on the functionality of the backup software, so any useful criteria that can be used, or some insight on companies using more advanced software and what benefits they offer over more traditional apps like backup exec would be really helpful.
I have installed Site Recovery Manager and the Storage Replication Adapter at both my production and recovery sites.  After pairing my production and DR sites I am trying to setup storage replication (NetApp in my case).  When I select the production or DR site and select the SRA tab the status shows a warning of "Unable to find SRA at the paired site", because of this error I cannot pair the SRA's.  I haven't found much information on this error, but I did come across this article:

The article talks about setting the environment variable for PERL but doesn't give any examples of what that variable should be.  Could the PERL variable be the cause of my problem? and if so how do I correctly set the variable path?  Any other suggestions on what might be causing this issue would be appreciated.  Thanks.
In an effort to learn about virtualization, I'd like to build a virtual machine; I'm specifically looking to build a Type I virtual desktop. What is the best specific software out there for that?
     Also, anyone know of any good tutorials on this subject. I thought I found some but turned out they focused more on the theory side of it. Anybody know of any resources that actually guide you, step-by-step, on how to install and configure it once you get the software?
Have a server that's running vSphere Web Client v6.5 to manage 4 vm's. It's creating snapshots at 12pm and 7pm everyday which is causing the vm's to freeze for a minute or so while those snapshots are being created. Looking for advice on how to turn off snapshots completely or adjust the schedule of them outside of business hours.
We have a 4-host vSphere cluster. (ESXi at 6.0. vCenter at 6.5.)
To expand vSAN, we had to reboot all hosts. Now HA is failing on 2 of them. (vSAN is healthy after initial congestion.)
- Have tried "Reconfigure for vSphere HA" many times.
- After putting in Maintenance mode, removed a problem host from inventory. Later added back to the cluster. Made no difference.
- Rebooting has not helped.

Message: 'Cannot complete the operation due to an incorrect request to the server'
Event log says: 'vSphere HA agent for this host has an error: vSphere HA agent cannot be installed or configured.'

Have looked at many KB articles including #2056299. It talks about checking fdm-installer.log file but no such file exists on any of the host, HA working or not. Have not changed configuration of the hosts in at least 6 months, other than expanding vSAN.

Please advise. Thanks.
Following best practices, I've been using the VMware Paravirtual SCSI controller for my disks.  I am able to create the templates by attaching the floppy which holds the driver for the disk, then i proceed as normal.  Eventually i'll disconnect and disable floppy drives as well.  I've had no issues with this configuration until now...  

In an effort to diagnose why my VMs cannot perform a quiesced snapshot manually, I have tried to uninstall VMware Tools, reboot, then reinstall VMware Tools.  Seems easy enough and very straight-forward (especially since it did once boot without tools during the creation of the VM).  Once I reboot my VM without Tools it does not come back online.  It gives me a "Stop Error:  Inaccessible Boot Device."

I've tried swapping the disk to an LSI Logic Controller to access command line.  During this time I have tried to assign the correct volume letters, copying driver files to the c:\ (even though it can't yet boot), and using bootrec commands to rebuild.  There is no system restore option available on the servers.

Since it has once booted without Tools, I suspect that when I uninstalled Tools it also removed a driver/driver reference within a boot file.  Does anybody know where that driver(s) is located, I suspect its on the system reserved partition so I can copy the files back?  Or if you know of a way to resolve this stop error that would also be great.  I should be able to uninstall VMware tools without a booting issue.

Hi all,

The hardware is a home lab HP Proliant ML110 G7.

A little Googling seems to suggest that I need to turn off VT-d, but that's not something I want to do, is it?

Thanks in advance.
I would like to upgrade my ESXi server from 5.1.0, 1065491 to the most current patch/ fix.

Does anyone know the Upgrade path from where I’m at to the current patch and how do I go about getting and installing the latest patch?

Thanks in advance for all help in this matter.
Hi there,

I have a charitable client (40 users) who is running 4 VMs on a HP ML350 Gen9 Host (ESXi 6), 64GB of RAM, Dual Hex Core CPU, 8 * 900GB disks.

1 * MS 2012 Server - Domain Controller
1 * MS 2012 Server - Exchange 2013
1 * MS 2012 Server - FileMaker Server
1 * MS 2012 Server - Terminal Server
2* 8TB QNAP NAS - Shadow Protect backup to NAS, Image Manager running on a spare Hyper-V server to replicate backup to mobile drives to take offsite.

I'm after some recommendations/tips are tricks from an expert for this type of environment, ideally using the equipment they currently have, to have a solid backup/disaster recovery solution, to protect them from attacks, ransomware, corruptions, and hardware failures, bear in mind they are a charity, so the Microsoft products and services are pretty affordable.

I'm thinking if it makes more sense, I could rebuild the spare Hyper-V server (HP ML350 Gen6 with 32GB RAM and Dual CPU) to ESXi 6, and take advantage of the features of the VMware better, but open to options to use the spare HP ML350 Gen 6 hardware.

Office 365 with Exchange is on the cards, but we are also happy to keep going with on-premise until the right time to migrate.

Thanks in advance.
Hi, I am trying to find the best way to calculate IOP's required in my environment, especially as I prepare to go from P2V in the very near future.

So, what tool(s), techniques, etc. do you use to accurately or pretty good estimations of IOP's your environments required as you set the stage for required equipment for your virtual environment storage pools, etc.?

Virtual Environment Platforms
VMware ESXi vSphere 6.5
Microsoft Hyper-V (2012 R2 & 2016)

Thanks in advance.
Here are my frustrations with vSAN. Will like feedbacks from others.

1. You cannot hot-swap or add a disk while an ESX server is up – like you can do with other storage systems. You have to shut down the server to format the disk RAID0 to be able to make it part of vSAN.
2. Often you cannot upgrade vSAN software without replacing the physical controllers on the ESXi servers. For example, I cannot go from 6.0 to 6.5 vSAN unless we replace PERC H710 controllers. (Not looking forward to it.)
3. About 20 to 25% of disk space goes to waste to make up for the fact that 1 out of 4/5 servers may go down.
4. Shutting down a ESXi server becomes much more complicated since data sitting on its disks has to be ‘evacuated’ (off-loaded) to disks of other servers, sometimes taking hours.
5. Booting up an ESXi server also takes much longer, since data on its disks has to reconciled ('initialized') with data already in production.
6. After rebooting an ESXi server, you need to wait for almost a day – while all data is resynced – before you can reboot the next ESXi server.

I'm having issues completing the Cisco Call Manager setup because it doesn't recognize my Windows 2016 PDC's NTP service.

Both are VMs on different ESXi hosts.
I can ping the Call Manager VM.
The switch recognizes the PDC as a Stratum 2 source.
My Windows domain and CM are on separate VLANs on this switch.
There's no access to the Internet or any other external source.

I did research and apparently the fact that the PDC is a VM can cause issue, but surely there's a solution.

Thanks in advance!
I have a Broadcom 5719 QP NIC card  in slot 5 of a PowerEdge T430.

The card is listed in the IDAC but isn't showing in ESXi 5.5.0, 5230635.

I have downloaded an installed the drivers but still not showing in Esxi.

How do I determine the correct drivers to use? Why would the NICs ports not be showing in ESXi?

IDRAC - show 4 NIC ports
4 port NICS card not listing

It read somewhere that if you want to keep particular applications secure to use a computer that is not connected to the internet ever. I am curious to know if this can apply to a VMWare or Virtual Box machine as well. If the host remains connected to the internet is a viable solution to set up your virtual machine with no internet access? Or does the host being connected run a considerable risk?
Our VMware environment consist of one vCenter server and 110 ESXi hosts.  I am looking for a means to nicly diagram the environment using Visio to it can be used to present to management. I have the following Powercli script http://virtualize-automate.com/wp/index.php/2016/01/03/generate-vcenter-network-diagram-visio-using-powercli/

but it errors out withe the following:
You cannot call a method on a null-valued expression.
At C:\SCripts\EnvironmentDiagram.ps1:57 char:1
+ $datastores=$stnobj1.Masters.item("Disks 1")

Can another recommend a scirpt or program that works well to do what I am looking to do. I am not looking forward to doing this by hand
I use Symantec Netbackup for backup, this application includes a report that is able to tell me some information about the old backups such as the size of each backup job and when they will expire from the storage (when they will be automatically deleted).

Since I also use Veeam to backup VMs, I am looking VeeamoneReporter to find similar report that can report the same information but, it does not seem like I can find it.

Any Help will be very much appreciated.

hi guys

we have power outage occurring in our building tomorrow. I'm going to have to power the Virtual Machines down, around 30 of them and then the hosts also.

Is there a way of creating a template of some sort in Vcenter and have it shut down via a schedule through a template without having to do it manually for every single virtual machine? Is there a way of setting up a template of some sort to apply to them all?

Thanks for helping
If you use a backup application e.g. backup exec/veeam for backing up of virtual servers, if the backup job completes fine day in day out, and assuming you have selected all relevant drives etc when you come to restore can there still be issues in restoring the data if the backup file is available, e.g. the storage hosting the backup files is online and healthy (these are disc based on not tape based)?

Can you give some examples of the type of issues that could STILL prevent the restore of the data from within the backup itself, this justifying the benefits of a test restore schedule. I totally get test restores are a good idea for many scenarios, e.g. to find if you have missed critical data off the backup selection list and therefore wouldn't be able to restore it, or to find issues with the backup media itself, e.g. tape failure, but I would be very interested to hear what kind of issues can still prevent the restore of data if a backup has been successful created each day, all relevant data was backed up,  and the backup file is easily accessible on disc.
when a service in your company requires a new virtual server to be created, e.g. they are implementing a new or upgraded version of their business application, what sort of paperwork do you have them complete and sign off in relation to backup requirements. obviously in some cases not all data on every drive associated with a machine needs to be backed up, but surely the customer, which technical advice, needs to request what data on that machine needs to be backed up. I am not sure how the process works at your company or what you call such requirements forms, so it would be interesting to here the best practices and may be the terminology you use for such paperwork so I can research further.
is it common when you use backup exec or veeam etc to also document your backup procedures for your virtual servers, or would any engineer with knowledge of common backup appliances be able to figure out the process relatively comfortably if no such documentation existed? what kind of things do you document to assist the knowledge of new engineers that they would not be able to glean from within the backup management software itself. and what kind of training is common when it comes to educating new engineers on the backup/restore process for virtual servers? e.g. from a management standpoint, what would you need to see in relation to training to have assurances new engineers understand the process from existing senior engineers.
Good afternoon,

I have the following doubt, in my virtual infrastructure in the inventory of the Vcenter does not appear my database vm, but if I go to the host, the vm if I can see it and it is on operational.

Because I can not see my vm from the vcenter, but in the host yes?

Attentive to your comments.
hi guys,

I've downloaded Vmware Converter 4.0.1 that can support Windows 2000 machines (don't ask, this thing needs to disappear fast from our servers!!). I've installed it on the local machine itself. However, our Vmware environment is Esxi 5.5. So whatever I do, it won't connect from the application to the Vmware infrastructure when I enter the credentials.

Can I export this as a Vmware Server 2.x (the only option for servers given to me) and then load it up on the Vmware Esx 5.5 environment?

Thanks for helping

I have created forest domain in 2012R2

I want to use /8 addresses to start with

Using  as IP address, as subnet mask and as gateway

Have installed DNS and AD DS on server

We have 5 esxi hosts I have this machine on 1st one, there are a number of networks pointing back to the existing domain

I want to set physical nic to have internet address, I know Andrew mentioned adding vlan or physical nic to the host, is it possible to add a brand new physical nic for this, when i look into adding a nic, i see the same choices pointing back to existing domain

What is the best way to approach this?
Is the Synology DiskStation DS1815+ Network Attached Storage Device (NAS) on the VMware HCL?
