vSAN Health Alarms in vShere 6.7u1

geob — Mon, 10 Jun 2019 18:15:12 GMT

I recently upgraded some systems in my lab to vSphere 6.7u1b. Now I see the vSAN warnings below.

CLUSTER1: vSAN health alarm 'All hosts have a vSAN vmknic configured'

CLUSTER1: vSAN health alarm 'vSAN Build Recommendation Engine Health' configuration issues

CLUSTER1: vSAN health alarm 'Performance service status'

I am not using vSAN, so how would I get rid of these warnings permanently?

Thanks,

Fedora 26 not mounting shared folders

geob — Tue, 05 Dec 2017 18:22:36 GMT

I'm attempting to mount a shared folder in Fedora 26 Guest, that is running on Workstation 14, on Windows 10.

In settings>options I have configured the Shared Folders. I have them always enabled, and I am sharing my documents folder. I am trying to mount using this command.

mount -t .host:/ /mnt/hgfs

or mount -t .host:/Documents /mnt/hgfs

either give me an error: mount: /mnt/hgfs: can't find in /etc/fstab.

Anyone know what I am doing wrong, or have a suggestion on a fix?

Thanks in advance.

VMware Workstation and Hyper-V are not compatible. Remove the Hyper-V role from the system before running VMware Workstation.

geob — Mon, 13 Jun 2016 12:16:58 GMT

Recently, I migrated a Windows 10 Virtual Machine, to a host laptop also running Windows 10, and VMware Workstation 12. When I attempt to power on the VM, I get an error popup that states: VMware Workstation and Hyper-V are not compatible. Remove the Hyper-V role from the system before running VMware Workstation.

At one point I must have turned on Hyper-V within the Windows 10 Virtual Machine. But I am unable to remove the role, because I must power on to do so, and VMware Workstation is not allowing the VM to power up.

Anyone know how I may resolve this issue?

Thanks,

Storage Report with percentage of overhead factored in?

geob — Thu, 19 May 2011 11:23:29 GMT

All,

I'm looking for a way to use PowerCLI to gather a list of all my LUNs, show Name, Capacity, Free Space, and then Free minus a % of overhead that would be factored in, and then output to a CSV file. I need the output to show GB not MB, and I would like to also hide, or remove any local attached storage. I need to be able to provide this to my storage team on a weekly basis, so they can get a quick look at our storage needs.

Currently I'm running vSphere 4.1 and my hosts are ESXi 4.1.

I'm no PowerCLI wizard, and have been struggling with trying to get a report generated that is formatted correctly and shows them what they need.

Has anyone else been able to produce a script that would produce something similar? Any help would be much appreciated!!!

Thanks,

geob

Identifying HA Primary Nodes in a Cluster

geob — Wed, 11 May 2011 10:59:09 GMT

I'm looking to identify the primary and secondary HA nodes within a cluster. I am currently running ESXi 4.1 on Dell Blade hardware. I want to make sure all my primary nodes are not in the same chassis.

I heard that this was posssible via PowerCli, I also have heard there is a command to force promotion to or demotion from a primary node. If anyone know how to do this with PowerCli, I would really appreciate the help?

Thanks in advance.

Adding large number of portgroups to DVS

geob — Thu, 28 Apr 2011 11:37:55 GMT

Anyone know how to add a large number of portgroups to a Distributed Virtual Switch? I have added portgroups to a Virtual Switch in the past by reading from a CSV.

This is the script I have used to create portgroups on a regular Virtual Switch.

# AddPortGroups.ps1

$esxHost= Connect-VIServer (Read-Host "Please enter the name of the ESX Host ")

$vswitchName = (Read-Host "Please enter the name of Virtual Switch ")

$csvPath= (Read-Host "Please enter the path to the CSV file ")

$vsw = Get-VMHost -Name $esxHost | Get-VirtualSwitch -Name $vswitchName

Import-Csv $csvPath | %{

$vsw | New-VirtualPortGroup -Name $_.pgName -VLanId $_.vlanId

}

Thanks,

Migrating hosts on DVS from vSphere 4.0 to vSphere 4.1?

geob — Tue, 26 Apr 2011 11:24:49 GMT

Because of some third party application changes to our vCenter DB we have been unable to upgrade from 4.0 u1 to 4.1. So we decided to build a new 4.1 vCenter server, and then migrate the hosts. I have done this in the past with no downtime to the VMs that were running on the hosts. But now I have a cluster with a Distributed Virtual Switch, and now the migrations aren't so simple.

Does anyone know how I may migrate the hosts that have the DVS from one vCenter server to another? I would prefer to do this without an outage to the VMs. If I experienced a slight network outage I could live with that.

Also need to know if it's possible to change the unique identifier of the DVS? I have migrated one host as a test to see what would happen. The test VMs continued to run but the hosts wasn't aware of the DVS. I then created a new DVS on the new vCenter server. I gave the DVS the same name as the DVS on the old vCenter server, and configured all the portgroups the same also. The difference in the DVSs now seems to only be the unique identifier. Not sure if it would help to make them identical?

Thanks in advance for any help you maybe able to provide,

Storage Migrate Large VMs spanning multiple datastores?

geob — Thu, 10 Mar 2011 14:23:12 GMT

I have several large VMs that are 2+ TB in size, and span multiple 500GB Datastores. I need to storage migrate these VMs to a different storage array. I don't have a problem moving smaller VMs, but not sure how I would move the large VMs. Does anyone know how would I go about using powercli to move these large VMs?

This is the command line I use for moving the small VMs that are contained within a single datastore.

Get-VM $vmName |Move-VM -datastore (Get-datastore $newLun)

Thanks in advance,

Copying machine folder and inventory contents?

geob — Tue, 08 Mar 2011 20:45:06 GMT

I am in the process of building a new replacement for my current vCenter server. I am currently running 4.0 u1, but will be building the new VC at 4.1. Once the new VC is built I plan to move the hosts to the new server. I need away to export all of my machine folders and list of VMs that they contain, and then create the folders on the new VC, and place the VMs back in the machine folder they belong. Is there a way to do this using powercli?

Thanks in advance,

VM Cluster Migration ?

geob — Tue, 01 Mar 2011 14:09:09 GMT

I have VMs that I need to live migrate from one cluster to another. Each hosts in both clusters have access to a large datastore we use as a swing volume. I have created a script that will first migrate the VM to the swing volume, then to a host in the new cluster, and then to its permanent datastore.

I plan to hand this task off to some other admins to perfom the migrations. These other admins have no powercli experience, and I have very little.

As you can see looking at my script that there is no intellegence built in. I have to rely on the admins to verify the portgroup that the VM is currently connected is avilable on the new hosts, and that the datastore has enough space without completely filling the LUN. I like to leave 40GB free on the LUN after the migration.

Does anyone know how I could build in some intellegence that would verify the portgroup exist, and the LUN has enough space?

VM_Cluster_Migration.ps1

------- Script Start --------

$tempLun = "SWING_VOLUME_NAME"
$vmName = (Read-Host " Enter VM Name to Migrate")
$newHost = (Read-Host " Enter Host to migrate " $vmName " to")
$newLun = (Read-Host " Enter new Datastore")
Get-VM $vmName |Move-VM -datastore (Get-datastore $tempLun)
Get-VM $vmName | Move-VM -Destination (Get-VMHost $newHost) -RunAsync
Get-VM $vmName |Move-VM -datastore (Get-datastore $newLun)

-------Script End ---------

Any help would be greatly appreciated.

How to remove Orphaned VM ?

geob — Wed, 26 Jan 2011 13:58:39 GMT

I have a VM that apperently failed a storage migration. I had the option to complete the migration, but that also failed because the demotion files were missing. I no longer need the VM, so I attempted to remove from enventory using the ProwerCli.

Get-VM VMNAME | Remove-Inventory

This command completed sucessfully, but now the VM is showing up in vCenter as being orphaned. I have no options to remove from inventory.

Does anyone know how I may remove the VM from vCenter via a SQL query?

I am running vCenter 4.1, and SQL 2005 SP3.

Thanks in advance,

powershell asp?

geob — Tue, 26 Oct 2010 20:00:20 GMT

Has anyone here had any experience using powershell asp?

I was able to use it to pull a Get-VM from vCenter, and dump to and html table. But I had to hardcode the server name, and creds in the code. I'm no html or asp guru, but I would like to prompt the user for server name, and their credentials.

Also I was really looking to code a page that would allow the users to put in a VM guest name, and get back info, like CPU count, Disk, Memory, and host information.

Setting CDs to Host Device ?

geob — Wed, 22 Sep 2010 13:14:32 GMT

I need to set all the VMs CDs to Host Device, and not Connected. I have been trying to do this using Set-CDDrive, but not doing something write.

This sets it not connected I think, but I can't figure out how to change from Client Device to Host Device.

Get-VM | Get-CDDrive | Set-CDDrive -NoMedia

Anyone know how to do this?

Thanks,

geob
