I am building a test lab and need some help.
Installed ESXi on a usb on a server.

Than added Harddrives.
The HDs are not being detected.
I do not know what on them.

How would you go about this??
is there any way i can have ESXi detect the HDs? i did rescan and it did not detect anything.

Any feedback is appreciated, I dont know where to start

I have a ESXi host running 6.5. I used VUM to find patches. Am I OK to just install them all?

Will it cause issues?

Please see attachment for updates

We have ESXi 6.0 hosts with vCenter appliance version 6.7. Needed to move vCenter and ESXi hosts to a new IP subnet. Changed IP address of vCenter a few weeks ago without a problem.

Yesterday, after putting an ESXi host in Maintenance mode, I changed its management IP and after hours of troubleshooting, the ESXi started responding on new IP, with old name. (There is redundancy in links.) However we cannot reconnect this ESXi host back to vCenter now.

This host and vCenter are on the same subnet. (They can ping each other.)  I have restarted management service of host a few times. Have also rebooted host and vCenter. Still get the same error: "Cannot contact the <> host (10.0.xx.xx). The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding."
Please advise. Thanks.
DFSRoots Namespace for VMware View Persona Management folder was created on the C drive. We have an E drive on that server that has DFSRoots Namespaces with other folders.

How can I move the C drive DFSRoots folder to the E drive DFSRoots folder and retain permissions? Need to do this as we are running out of space on C drive plus it should have been created on the E drive anyway.

Thanks for any help
how is the vmkdump files getting created on datastores.
I run vSphere  client 5.5.0 build 5067769 on Windows 7. found it "console" can't display Windows screen.
When use VM > open console is ok.

However, the VM operation system actually running is normal.

How to fix this problem?
hi guys

One of our directors has asked me some questions about what we could do in the future to reduce the need for I.T presence at one of our countries and instead have it so that the support is almost entirely run from the U.K instead.

The site at our other country has two separate sites. One is a warehouse, the other is an office. The total number of users at both sites together is around 100 users. There are firewalls at both sites. There are VPN's connecting both sites. Those sites are also connected to us in the U.K

I mean, one of the only ways to reduce the I.T presence in one place is by reducing the types of physical hardware/equipment which would constantly require physical presence, right? So things like switches, PC's dying on you, printers, file storage, SAN disks needing replacement, you name it all will require some level of physical intervention.

By heading towards Office 365 and Exchange online, would you say that helps slightly reduce the overhead?

Along with that, how about instead of having PC's that are powerful, have decent thin clients and have high enough bandwidth to give them connectivity to their own virtualised machine on like a cluster of Vmware/Hyper-V servers on a SAN that have been spun up for them. So that would then reduce the possibility of hardware/disk failures on site and instead have them run on virtual terminals. Are there performance issues with that? Are the costs in the longer term reduce and is the quality …
Hi - I am setting up a SAP HANA environment based on VMware 6.5 using RHEL 7.5 VMs.

One of my VMs has a number of drives (100GB OS drive / 32GB Swap / 50GB Binaries / 32GB Shared Data / 750GB DB / 750GB Logs), 48vCPU, and 768GB RAM and resides in a number of different Datastores.

My OS and Swap files share the same disk and datastore.

When I boot my RHEL VM, it tries to create the Swap space to match the amount of RAM = 768GB which instantly fills my storage.

I want 32GB configured for Swap space.

Am I missing the obvious? Is the sudden grabbing of disk space to match the amount of RAM expected behaviour?

Any help or guidance much appreciated
I am looking for desktop imaging system recommendations. A little background, we are currently using Acronis but have outgrown it. I am looking into Quest Kace and SmartDeploy.

I am liking the features of SmartDelpoy much more and would prefer to have a more modern imaging system like that as opposed to Kace. I know there are other options out there like VMWare Workspace ONE, Microsoft System Center Configuration Manager, and CloneZilla.

Does anyone have any experience with any of these or would be able to recommend something better? We would prefer a cloud solution, if there is one.

We moved a cluster to a datacenter in another city and would like to rename the hosts in the cluster accordingly (the hosts are named by the city they're located in, so I need to change from OLDCITYvmhost01, 02, 03, 04 to NEWCITYvmhost01, 02, 03, 04). I believe the process to be:

Put the host into maintenance mode.
Disconnect the host from the vCenter server.
Connect to the host directly (I am using the stand-alone client).
Go to Configuration > DNS and Routing > Click Properties... then edit the name accordingly.
Click OK.
Go to vCenter web client.
Go to the cluster.
RIght-click cluster and choose Add Host.
Choose renamed host and configure through wizard.
Exit maintenance mode.

Will VMs migrate back to this host, now with a new name? I suspect they will in that the host is part of the cluster and the cluster is configured for HA and DRS. However, I wasn't sure if the VMs that were migrated off of the renamed host when it was put into maintenance mode would have some issue moving back.

Please let me know if there are other locations I need to update the host name, any caveats or errors I may encounter with the cluster, or if there is a reason besides personal preference to use the host's web client to do this.
Much appreciated.

How to get Alerts to EMail or SMS from VmWare Horizon, version 6.2

I can see icons turning red for node, and need to get this exported out for someone that... gives poo to resolve issues. Currently it's totally random if someone see the RED node or a user contacts the team.
VMWare Host complaining about a fault. Lost connection to NFS Server. Whats confusing to me, nothing has been lost- everything is up and working fine. the only thing I did a while back was add an additional host as a test then took it out of the farm. ive restarted everything too and still getting same error.

Not sure how to further troubleshoot this.

I added a vlan to a vswitch and see it with active ports 0
Under Physical adapters all VLANs show, but not this one so what am I missing in adding the VLAN?
I am re-building my Veeam serveur moving for 4.x to 9.5 and want to be sure and safe I'm doing the right thing,

A consultant put in place a few jobs but didn't seems that sure of the configs to put.
I want a full backup set out every friday and full on-site every nights (one to a NAS and one to a local USB drive)

My main job goes to a NAS.
As 20 restore points
"Configure secondary destinations for this job" is not check
It's a Incremental
"Enable application-aware processing" is checked
"Enable guest file indexing" is checked
runs daily

got a Weekly on F: drive
1 restore point
"Configure secondary destinations for this job" is not check
"Active full backup - Create active full backups periodically on Thursday"
This job I remove every Fridays and bring home and I rotate it using 8 hd
"Enable application-aware processing" is checked
"Enable guest file indexing" is not checked
Runs everyday at 8pm

And got a BackupCopy job called "backup on external drive"
Target is E: removable HD
31 restore points
Runs continuous

1- Is all configs efficient?
2- And is there anyway on the job "backup on external drive" I could bitlocker that drive when it is not in use.
I activated bitlocker but coudn't create a batch job that would decrypt before backup and re-crypt afterwards.

Veeam is erroring on backups for a handful of VMs due to errors creating snapshots.  I have gone into vSphere and tried to manually create a snapshot and also receive an error.  VMware is saying "An error occurred while taking a snapshot: msg.fileio.generic." & "An error occurred while saving the snapshot: msg.fileio.generic."  We had some storage issues a few days ago where one of our datastores on an HP MSA ran out of space.  I added 200GB to the datastore to free up some room.

I guess my question is when creating a snapshot, I have one of the VMs that I checked and the vmdk is 100GB but the Datastore is showing 259.89GB free.  Is there a way to verify the freespace?  I have about 10 vms failing backups with the same errors and they all seem to be residing on the same Datastore.  Not sure where else to look to troubleshoot?

I have 5 ESXI hosts. All EXI Hosts can see/have connections to 2 HP fibre Sans and a few ISCSI SANS.
Each ESXI has an add on HP 8GB FC to PCI Express HBA Card.

one of the ESXI host had the system board replaced. When ESXI came back up, it had no problems seeing the ISCSI SANS. But it was unable to see the 2 HP fibre SAN. Looking at the storage adapters, Vsphere client shows "VMHBA1 fibre Channel unknown" while "VMAHBA2 Fibre Channel online"

I have rescan for hardware changes. I see no options to re-attached/mount storage back. How do I get the VMHBA2 to reconnect to the HP SAN? All the other ESXI hosts can see it.
When setting a VM's Latency Sensitivity to high, I know you set the CPU and Memory reservations or 100% but are there other changes this setting does to the scheduler or anything else?
HI Exeprts

we upgraded our Vcenter to 6.7  9433894    on windows

and our ESXI servers to  VMware ESXi, 6.7.0, 8169922

my question that i heard that Vmware will stop Vcenter on Windows . is this right and on which version

plus is really the appliance will be good enough to cover all we need . our vcenter on windows with MSSQL DB standard edition work very well

and what about the new appliance is really can cover third party plugins and vcenter linked mode  etc

plus they said in 6.7  they will have full HTML GUI and flash will go away in which version

also said for GPU sharing with new version we can make Vmotion  even if the VM on

kindaly advice
I have a physical HP DL 380 G7 server 80 GB of memory, 900 GB storage, 1 CPU (Processor cores per socket 4 and total logical processors 8, with hyperthreading enabled).

Every client (5 guest in total) are working via their own terminal server, connected via a remote desktop gateway and asa 5510 firewall on their own vlan. OS is WIN 2008 r2,VMWare version is V6, with latest HP servicepacks on it.

Memory total is 26 GB used

Harddiskspace used is 576 GB

I gave all the guests a total of (vsocket x cores per socket =) 14 VCPU. But as i can see i have only 8 VCPU available, so am I overprovisoning?

My clients are complaining about peformance and freezing of the Remote desktop they run on. I can also see it sometimes. The screen stops, my ping times are rising to 15-25 ms in 2 seconds and than it disappears again and they can work. (i did this from a terminal server from a client and pinged the firewall and the internet).

Is this because of the over-provisioning (14 VCPU in stead of 8 VCPU available ??) does anyone has a solution or has experience with this kind of slowness in VMWare?
Active Protection takes the fight to cryptojacking
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

We have Ubuntu 18.04.1 LTS running on a virtual machine in VMWare Workstation 12.5.7 build-5813279.

The network settings appear to be correct however every time we boot it we get the grey icon with the question mark.  We can disable the network and reenable it and everything is fixed.  Can you tell me how to fix this issue as it is rather annoying?
I'm looking for some feedback or ideas on how to handle multiple HTTPS servers sharing same public IP behind a SonicWALL.

For example:

https://exchange.mydomain.com/owa = flows to Exchange server
https://application.mydomain.com/app = flows to application server

My client has an on-prem Exchange server.  I know from experience that you cannot just use a redirected port with Exchange because the server is constantly rewriting the URL (minus the modifications) making it inaccessible.  Exchange must use 443.

However, my client also wants to publish another site, on another IIS server on the same LAN as the Exchange server, behind the same Public IP, and is not keen on using a custom port.  The desire is to keep the URL as simple as possible for all the staff in the field.  This new IIS server will see a lot of traffic and is considered Mission Critical.

I know with the SonicWALL I could split the Internet connection, get a second Public IP from the ISP, therefore providing a second WAN interface.  That would solve the problem by presenting a second Public IP, but it would also have a negative effect on the available bandwidth for the first WAN connection.

There is absolutely no interest in moving Exchange to another port.  I'm not even sure that's entirely possible, but even if it is, Exchange is too well established where it is, and since it's already working I'd rather not tip over that apple cart regardless.

SonicWALL has a feature that I've seen called …

I am looking for a Flatbed scanner needed for VDI VMWare Horizon. Can anyone recommends one that works well?
Wondering how to combine output from get-vm and get-adcomputer into the same CSV.

I am doing a project where I need to update VMWare Tools, but only dev domain joined Windows servers.

I am hoping to combine the outputs from get-vm and get-adcomputer into a master list, and matches records based on "Name".

For example:

$ADServers = Get-ADComputer -Filter {(OperatingSystem -like "*windows*server*") -and (Enabled -eq "True")}
$VMs = get-vm

CSV includes $VMs.Name, $ADServers.Name, $ADServers.DistinguishedName, $VMs.PowerState

$ADServers.Name and $VMs.Name should match in theory, however not all VMS will be joined to the domain so $ADServers.Name and  $ADServers.DistinguishedName may be empty on some records.

Is this possible?.

I inherited several Windows 7 VM's that are wasting a huge amount of disk space. My thought
was to use Converter to trim some fat. The conversion worked but the VM won't boot properly.
I'm in an infinite loop of Starting Windows/seeing a BSOD for a very-pico second/Windows Error
Recovery. All options in Windows Error Recovery send me back into the loop.

Any suggestions on where to start would be greatly appreciated.


I am running several VMware 5.5 hosts on OEM servers, with each using a MegaRAID LSI 9260-4i SATA RAID controller card with accompanying battery backup unit.   Hosts are managed by a VCenter 5.5  virtual server.  Drive configurations on each host are SATA drives paired in RAID-1 configurations.  I recently got an alarm sounding on one of the servers that 1 of the SATA drives had failed.  I installed the Avago StorCLI utility, and using a  SHOW HEALTH command saw that the state of the virtual drive was degraded, and that the failed drive was on the LSI controller's connector P1.  I shut the system down, pulled out the failed SATA drive, and replaced it with a same-size SATA drive.  On startup the controller card began to beep again, as it was still detecting the degraded virtual drive.  I hit CTRL-H to enter the LSI controller's WEB BIOS and went to add the replacement drive to the degraded virtual drive.  Unfortunately, I could not remove the failed drive from the original RAID-1 Drive Group 0, as it still showed the failed drive in the original mirror setup, as a MISSING PD.  As such I could not add the replacement drive into the original Drive Group 0.  When I tried to add the replacement drive into the Logical Drive setups, the interface created a new Drive Group 1 and wanted to add the new drive to that.  Ultimately I had to declare the new drive as a Global Hot Spare, and I then saw the system start  to rebuild the Drive Group 0 using the new hot spare …
