In Vmware VM and Templates , I have several folders, and in each folder there are multiple VMs.
I want to know to which Host and Cluster each VM belongs to
is it possible to get the list through Powercli ? or it needs a script?

for instance:

VM Name,        Cluster Name,        ESX Host Name
VM 1		    Clust1	                    ESX1
VMX                    ClustA                    ESXB  

Open in new window



Thank you

Hello - we currently backup all of our VMs and Vcenter Server, but do not have any type of backup running for our Hosts themselves.  is this something we should be doing? or is it even possible?  If a host crashed, is it easy enough to rebuild a new ESXi host and restore our VMs to that one?  Just seeing what the experts think on this.

Thanks

Hi,

We have a production Microsoft SQL Server 2014 - 12.0.2000.8 (X64)   Feb 20 2014 20:04:26   Copyright (c) Microsoft Corporation  Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200: ) (Hypervisor)  and RTM version. Out of 4 GB ram sql server assigned 3 GB RAM. User complained about they are having some performance issues while they update their records and it takes several hours.

What i found that they kept their all data, log, tempdb and backup in a same drive. Each databases memory usage are very less. I asked them we need to separate drives to keep data and log file separately.

But SAN Admin replied that, Since we only have one slow SAN I'm not sure moving this data to different drive letters is going to matter if they are still on the same spindles on the same SAN. It may be time to buy a physical for this if better performance is needed.

Please advise me what else i can check and give them suggestions.

Thanks

If I don't click "Power on VM after restoring when I fall back the replicas to the production environment, how can I  start the VM in the production later  ? Should I shut down the replicas  and start the VM manually ?

Will the job under Replicas job will still shown as "Active" in this case ? How should  i handle this job ?

Thx

We have a Dell server running ESXi 6.5 connected to an iSCSI SAN using four paths on Round Robin, the SAN has dual controllers for failover but the iSCSI sessions are connecting to the failover path rather than the preferred primary path although there are no issues with the networking equipment via the preferred path.

I have attempted to make configuration changes via vCenter to get the iSCSI sessions back on to the preferred primary paths but it keeps reverting to the failover path causing an error light on our SAN (caused by error "Virtual Disk(s) Not On Preferred Path").  So in an attempt to correct this error light on our SAN, I've removed the static targets and the discovery targets on the ESXi server, removed the iSCSI sessions via SSH, then did a rescan.  The failover paths are still being reconnected after a rescan of the HBA's although those failover paths do not seem to be saved anywhere.  Why are failover paths being rediscovered

I did a vCenter upgrade from 6.0 to 6.5 a couple weeks ago and is working fine.
I just upgraded one of the 2 hosts (dell custom image) from 6.0 to 6.5 and vCenter no longer sees it (still shows offline after upgrading)
When connecting to the host directly, it says it is not being managed by vCenter.
i suppose i could remove from inventory and add again but is this expected?  i can't find anything on it.

closest thing i found was this but applies to 5.5

Could you help me understand this , I came up with circumstance where one of the VM has “HD Audio “  in the VM level but when I try to vmotion to another ESX host  it throws error

“VM is configured to use a device that prevents the operation: Device 'HD Audio' has a backing type that is not supported. this is a general limitation of the virtual machine's compatibility with the ESXi version of the selected host”

Help me understand this concept , how is the Audio device tagged to ESX host when there is no affinity rule set ?  what make the ESXi host think its not compatible to be vmotioned from the existing ESXi host where the Audio is enabled on the VM level .

Also the interesting part is there is Secondary VM which has this same  Audio configured in other ESXI host even if I try to select that ESXI host iam not able to vmotion it  .

Any one has any resolution ?

My setup is: HP Proliant 360G8 server with a p222 adapter added. On this adapter I've connected a external HP Ultrium tape unit. On the server I run VMware Vshpere 5.5. I've setup three virtual servers (DC/Exchange, file/printer and remote access desktop server). The fileserver also functions as the backup server with Symantec BackupExec 14 running. I've connected the external tape unit to this machine in the virtual machine setup. In backup Exec I've configured backupjobs (one running daily, one for fridays; the daily one runs over the designated tape each week, the friday jobs run on five tapes so I can run back into time for 5 weeks). The jobs are complete backups of all three servers (including all data, system state and bricklevel backup of Exchange).

What I run into is that at least once a week the fileserver completly 'freezes'. This goes to the point that you can't even power off from the VMware consile and need to reboot the whole server to get everything working again. From the log files i see this happens at a point just after the backup finishes. On most occasions, but not on all, the P222 card is shown as 'dead' in VMWare manager.

What I have done so far is: installed both windows server and backup exec completly fresh (as a new virtual server). I've replaced the P222 with a new adapter. I've update the firmware on the P222 and the driver in VMWare (april 2017). But nothing changes this behavior.

After the server 'freezes' it is completely …

hi everybody
i tested DAC in vmware like this post
https://blogs.technet.microsoft.com/canitpro/2013/05/06/step-by-step-protecting-your-information-with-dynamic-access-control/
but when in effective access tested access for my user it had all deny permision and limited access by the rule ,however i apply to it read,write and modify permission with the rule
and check the steps in above post two times and everything allright.
Does anyone have a comment?

Current environment is two 2012r2 servers running Exchange 2016 CU2 on VMware 6.0 .  Just completed converting the thin client databases to thick client.  I am starting to build a third Exchange server with 2016 CU6 with the intention of building redundancy before I begin updating the two existing servers.  I understand the basic process of adding a server to the DAG but there are details I cannot find clear answers to.
1.       Do I need to create empty databases with the same names as the active databases on the new server before I add it to the DAG or will the DAG automatically copy the active databases into the new member?
2.      Can I simply restore backup copies of my active databases in the DAG to the new server and then add the server to the DAG?
3.      As I get the other servers to the same CU and updates will the failover cluster be created or do I have to make that happen?
Most of this seems common sense but I want to avoid the scrambling for a solution if it goes bad.

When I add a Dell server running VMWare ESXi to my Open Manage Essentials installation for hardware management; it appears that the servers change to 'unknown' status after a few days.

If you have Dell Open Manage Essentials monitoring hardware with the VMWare ESXi host O/S loaded on them; what have you done to fix these servers from going into 'unknown' status (grey question mark)?


I thank you in advance for your time.

Hello,

i have 2 ESX servers.

1st server is running ESX6.0 and is in the network 192.168.1.x
2nd server is running ESX6.0 and is in the network 192.168.0.x

both networks are on a different location. We have created a VPN tunnel between the 2 locations.

i have installed vcenter in the 1st host running in the 192.168.1.x network.

when i add the 2nd host in the vcenter than this works fine, i see the host and and can create vm's.

but when i Launch the Virtual Machine Console from a VM on the 192.168.0.x network then i get an error saying that it cannot connect to the MKS in server 192.168.0.x:902

When i Lauch the Virtual Machine Console from a VM on the 192.168.1.x network then all works fine.

what am i missing?

I'm trying to test if the VM workstation and the main window is connected with each other. However when I tried to ping from VM workstation to the main window, it states that Host cannot be found even though when I tried to ping in the  reverse direction the packets could reach. How can I solve this problem? The adapter setting for the VM workstation is NAT.

Good morning companions,

I have the following problem with my SRM service since when I try to start it, it appears me next message:

the vmware vcenter site recovery manager server service on local computer started and stopped. some services stop automatically if they are not use by other services or programs

I can not even restart them either, I tried rebooting the server but the problem persists.

Please support them.

Best regards.

Hi,

Sometime ago I extended a VM C drive on a Windows 2008 server and afterwards it wouldnt boot up so I had to restore from back up. Im about to carry out a similar operation on a different server which has three drives of which one is the C drive which currently sits at 275gb. I weary of doing the same process again in case it breaks the server (windows 28k/SQL2008) so looking for any sound advice and gotchas to look out for.

Thanks

Hello,

I have the following situation: 1 physical server that runs Oracle 11g (2 x E5-2643 v3, 64GB RAM) on Oracle Linux.
The client bought another identical server, for fail-over and redundancy purposes.

This looks like a good opportunity to virtualize the server.

Basically there will be 2 physical servers in a cluster.

Questions:

1. What is the recommended virtualization solution for Oracle?
2. What licenses will be necessary, if he goes with VMware ESXi?
3. What type of shared storage do you recommend for the cluster?

Thank you.

ESXI host is experiencing random disconnects of VMs. The host itself is still powered up and VMs on it are reachable via RDP.  This has occurred periodically with this and other hosts within the same physical rack (and most likely the same switch). I believe it is a hardware networking issue or a configuration between the host and vCenter. The VMs within vCenter will gray out for approximately 15 to 20 seconds.  Any idea where the solution is or where I should begin looking to resolve this problem?

I've asked this before and have never received a real answer.

All machines run Windows 7 64-bit on a domain with AD.

On our in house VM's, they are set up in such a way that the Public user folder is on the C drive. However, all regular user folders are on the D drive.

Unlike our physical machines in which all user folders are on the C drive and when I copy a file to the C:\Users\Public\* folders it replicates to all users' folders. The VM's with the D drive user folders will not replicate anything I place in C:\Users\Public\*.

Does anyone know why this happens? Unfortunately, this is the way the system was set up before I got here and I have tried reaching out to the SA who designed this but he has been unresponsive.

I need to be able to push a file out to these VM's so that it appears on every logged in users' Desktop folder. The best way I know how to do this is to push it to the Public\Desktop folder. But it's not working.

It works fine on our physical machines, just not the VM's with the wonky user folder setup.

We would like to move our vCenter databases to another MSSqlServer. However, we do know what they are called on the old MSSqlserver (we have a lot of databases). How do we find the name and location of the databases and if they are still being used?

- vCenter 6.5
- ESXI 6.5

- vCenter Server: Microsoft Windows Server 2012 (64-bit)
- Old MSSQL Server: MSSQL Server 2008
- New MSSQL Server: MSSQL Server 2008 R2

Dear All


             Any one know what is the default login id and password for vsphere web client , i have installed vcenter 6, but i can not login to the web client, any help would be appreciated !

Goodnight,

I am currently presenting the following drawback with my VDP to run backups on my virtual infrastructure, motivated that when creating the backup scheduling task, the same runs the snapshot, but at the time of creating the backup fails to 10% of having started , then removes the snapshot, but the backup fails, the maximum of the percentage that reaches is 16%.

They are Windows Server 2012 R2 Standard servers.

The tests I have performed are as follows:

-Migrate these servers to all the ESXi of my infrastructure.

-Run a VM vmotion storage to another datastore.

-Enable internal firewall rules in the operating system to enable port 902 on both the windows server and the VDP.

-Registration of the Vcenter in the VDP Utility Configuration, together with the restart of the VDP appliance.

-Modify the Windows DiskEnableUUID virtual server parameter to False.

-Enable the Windows VVS service.

-Restart Management Agents on all ESXi.

However with all these tests the backup fails, the error messages that appear are: Failed to attach disk and miscellaneous error, I do not know if it would be a good idea to modify the etc / hosts of my vcenter in Windows and to point to all the esxi in the file to verify if the backup is successful.

I also pay attention to your comments and suggestions.

Best regards.
