VMware: Disable HotPlug capability for virtual machines with PowerCLI

January 16th, 2016 2 comments

Last week I had to change VMX files for 500 XenDesktop machines because the users where able to eject removable devices

To mass disable HotPlug capability by editing the .vmx file via PowerCLI I used the following script:

$key = "devices.hotplug"
$value = "false"
get-cluster "CL02.XD" | get-VM -Name 000-CXD* | foreach {
  $vm = Get-View $_.Id
  $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $vmConfigSpec.extraconfig += New-Object VMware.Vim.optionvalue
  $vmConfigSpec.extraconfig[0].Key=$key
  $vmConfigSpec.extraconfig[0].Value=$value
  $vm.ReconfigVM($vmConfigSpec)
}


Optional (manual) options:

You can disable HotPlug capability using the vSphere Client or by editing the .vmx file.
Note: You can disable HotPlug capability for PCI devices such as e1000 or vmxnet3 NICs.
To disable HotPlug capability using the vSphere Client:

  1. Connect to the ESXi/ESX host or vCenter Server using the vSphere Client.
  2. Power off the virtual machine.
  3. Right-click the virtual machine and click Edit Settings.
  4. Click the Options tab.
  5. Click General > Configuration Parameters > Add Row.
  6. Insert a new row with the name devices.hotplug and a value of false.
  7. Power on the virtual machine.

To disable HotPlug capability using the vSphere Web Client:

  1. From a web browser, connect to the vSphere Web Client.
  2. Log in with Administrator credentials.
  3. Navigate to the virtual machine you want to modify.
  4. Right-click the virtual machine and select Edit Settings.
  5. Click the VM Options tab.
  6. Click Advanced > Edit Configuration > Add Row.
  7. Insert a new row with the name devices.hotplug and a value of false.
  8. Power on the virtual machine.

To disable HotPlug capability by editing the .vmx file:

  1. Power off the virtual machine.
  2. Access the ESXi/ESX service console using an SSH client.
  3. Open the virtual machine configuration file (.vmx) in a text editor. The default location is:
    /vmfs/volumes/datastore_name/vm_name/vm_name.vmx
  4. Add the line:
    devices.hotplug = "false"
    Note: This setting does not interfere with HotPlug CPU/memory.
  5. Save and close the file.
  6. Power on the virtual machine.

Note: Supported upgrade paths to VCSA 6.0 U1 include from 5.1 U3 & 5.5.

While on the topic of upgrades, going from VCSA 6.0 to 6.0 U1 is quite simple. First, you’ll need a patch ISO, which can be found on here. You ‘ll notice there are two patch ISOs, FP and TP.

Download VCSA patch from here.

FP
is a full product patch for VC & PSC appliances only.

TP is third party patch spanning multiple products, such as VCSA, vCenter Windows, VUM, PSC appliance and windows.

 

To update/patch your vCenter 6.0 Appliance, please follow the below steps:

  1. Connect directly to vSphere host which running vCenter Appliance
  2. Take a snapshot of VCSA
  3. Connect downloaded ISO file to the VCSA VM
  4. Log in to the VCSA via SSH
  5. Run the following command
    To mount ISO and accept EULA:

software-packages stage –iso –acceptEulas

image

 

To stage ISO:

software-packages install –iso

To see  the staged content:

software-packages list –staged

image

 

To  install the staged rpms:

software-packages install –staged

VMware: Toggling the vCenter Server Appliance 6.x default shell

December 18th, 2015 No comments

This article provides vSphere Administrators steps to toggle between default shells available on the vCentrer Server Appliance (vCSA). 

Currently, the vCSA is bundled with these supported shells:

  • Appliance Shell
  • BASH Shell
    Today I tried to upgrade vCenter Appliance 6.0.0 to Update 1, after runnning command “software-packages stage –iso –acceptEulas” I receiver message:

    -bash: software-packages: command not found

image

 

Switching the vCenter Server Appliance 6.x to Appliance Shell

 

  1. Log in to the vCenter Server Appliance via SSH.
  2. Run this command to change from using the BASH Shell to the Appliance Shell:

    chsh -s /bin/appliancesh root

  3. Log out from the BASH Shell and re-log in for this to take affect.

Result

After restart the SSH sessoin I was able to run commands in bash shell

VMware: Perf Charts service experienced an internal error

December 16th, 2015 No comments

A few weeks ago a customer asked me to take a look at the following warning message in VMware vCenter when the Performance Tab in the vSphere client is being opened.

  

Perf Charts service experienced an internal error.

Message: Report application initialization is not completed successfully. Retry in 60 seconds

 
image


Troubleshooting time

Global checks:

  • The Windows Event logs are clean
  • VMware vSphere (web-) services are started with normal credentials
  • I was able to restart service accounts with domain based credentials (no locking)
  • Windows Firewall was enabled but no drops in the logging
  • No recent installed Windows Updates
  • No unplanned restarts or crashes
  • The installed certificate was not expired
  • The installed certificate was 2048 bit
  • No conflicting webserver ports at the vCenter server
    ..some more troubleshooting

I checked the wrapper.log and stas.log files located at the following location:

Path: C:\ProgramData\VMware\VMware VirtualCenter\Logs\

clip_image002

 

 

 

 

 

 

 

 

 

  

clip_image002[5]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hmm, he logging shows that there are problems with the installed vCenter SSL certificate:
 

Error constructing private key..

..Error decrypting password

After some troubleshooting I saw that every time I open the Performance tab a new webserver SSL private key decrypting error was written in the stats.log.

I already had checked the expire date of the installed SSL certificate, it was a normal 2048 bit wildcard certificate.. oh, eh, wildcard..?? Let’s see if it is supported:

“The use of wildcard certificates are not supported with vCenter Server and its related services. Each service must have its own unique certificate”

Nope, it is not! Maybe this is the root cause.

After checking the SSL requirements at the VMware KB  I found the SSL format which is needed to generate the certificate: OpenSSL Version 0.9.8 must be used. If you do not use this version, the SSL implementation fails. <– I couldn’t check this because there was no documentation of the SSL generation

 

Solution

The customer used a wildcard SSL certificate which is not supported

VMware: Increasing the disk space for the VMware vCenter Server Appliance in vSphere 6.0

November 20th, 2015 2 comments

Some months ago I installed 15 new vSphere 6.0 hosts with local flash disks. After installation I configured the VMware Syslog Service at the vCenter appliance. Few weeks later the vSphere web-client shows some warnings about disk usage

Problem

Filesystem /dev/mapperlog_vg_log usage 100%, mounted on /storage/logs

 
Use this command to verify which disk is experiencing disk space issues:

image

 

 

 

 

 

 

 

 

 

 

 

 

Solution

As you can see the the /storage/logs mount point is located at VMDK5

image

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Edit de vCenter appliance virtual hardware, select disk Hard disk 5 and increase the provisioned size, in my case from 10 to 20 GB

image

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Once the virtual disk has been increased, return to the SSH session and execute this command to automatically expand any logical volumes for which the physical volumes are increased:

vpxd_servicecfg storage lvm autogrow

 

image

 

 

 

 

When the grow operation is successful, you see output similar to:

VC_CFG_RESULT=0

 

Run this command to confirm that the virtual disk has been successfully grown:

df -h

image
