PowerCLI: Reconfigure for vSphere HA


Sometimes when you change something to the vSphere HA configuration like an Advanced Option, you have to reconfigure vSphere HA on each host inside that particular cluster. You can do that by hand via the Reconfigure for vSphere HA.. option inside the vSphere (Web) Client:

Or you can use the following PowerCLI one-liner to perform this step on every host inside that cluster.

Get-Cluster <clusterName | Get-VMhost | Sort Name | %{$_.ExtensionData.ReconfigureHostForDAS()}

Just change <clusterName> the to the name of the cluster en open PowerCLI, connect to the vCenter server and run the one-liner.

ssl-updater.bat: Cannot validate the Lookup Service connection: 3


Last week I was working on a change plan to update one of our vSphere environments with new SSL certificates on vSphere 5.1 installed on a Windows virtual machine. When I tried to update the SSL certificates of the vCenter Inventory service, I received the following error message:

image

In the vc-update-ssl.log log file I saw the following message:

Cannot authenticate user – Return code is InvalidCredentials 3

The first thing I thought was a typo when entering the password for the SSO Admin user. But after three times I stll got the same error. So the next step was logging into the vSphere web-client as admin@system-domain. But I was unable to logon because the associated user’s password is expired. That explains a lot.

Lucky me VMware has a KB article with a solution: KB2060150. The reason why the user password is expired, is because of the default password policy:

This issue occurs when the Admin@system-domain password has expired; the default is 365 days.

To resolve this issue you have to change the password policy and in particular the MAX_LIFE_SEC column in the RSA database.

Follow the steps described in KB2060150 to change the MAX_LIFE_SEC column.

To increase the MAX_LIFE_SEC column:

    1. Stop the vCenter Single Sign-on service (SSO).
    2. Log in to SQL Management Studio.
    3. Go to the RSA database.
    4. Expand Tables and highlight the dbo.IMS_AUTHN_PASSWORD_POLICY table.
    5. Right-click and select Edit Top 200 Rows.
       Scroll over to the MAX_LIFE_SEC column. The default setting is 31536000 seconds (365 days).

       Note: Select the policy that contains Password Policy for SSO system users within the NOTES  field.

    6. Increase this value (for example: 47304000 seconds = 546.5 days, 63072000 seconds = 730 days, 90000000 seconds = 1041days).
    7. Restart the vCenter Single Sign-on service.
       Once the service has started, log in the Web Client to vCenter Server with admin@system-domain:default URL is https://vCenter-server-fqdn:9443
       Navigate to Administration > Configuration.
    8. Click the Policies tab.
    9. Click Edit.
    10.Change maximum lifetime to 0 (never expire) or enter the approximate number of days corresponding to the value you set in the database, MAX_LIFE_SEC field above.
       Save your changes and exit the edit.

Note: Instead of steps 6 and 7, you can scroll to the column named PERIODIC_EXPIRE, and set that value to 0. This will prevent password expiration. You should only do this if your security policy allows non-expiring passwords.

When you succeed in step7, you can continue updating the SSL certificates with the ssl-updater.bat tool.

HP’s September VMware driver bundle and issues with Emulex CNA’s


Update 08/10/2014: HP support recommends to install the following versions of the Emulex firmware/drivers.

Install the following driver and firmware version for the NIC and install on server and check

As it is a ESX 5.1 we would use BE2NET driver

Driver: 4.9.488.0 – http://www.hp.com/
Firmware: 4.9.416.0 – http://www.hp.com/

You can read more about the issues here at http://www.techazine.com. I saw the same symptoms on brand new HP BL460 Gen8 and vSphere 5.1 update 2, the latest build: VMware-ESXi-5.1.0-Update2-2000251-HP-5.68.30-Sep2014.iso released on 2014-09-08.  Hosts randomly disconnects from vCenter, even if those hosts are in maintenance mode (lucky me).

The driver causing the issues is version: net-be2net 10.2.293.0-1OEM.510.0.0.802205 Emulex VMwareCertified 2014-08-25. More information about the drivers included in the latest custom ISO can be found here: http://vibsdepot.hp.com/hpq/recipes/September2014VMwareRecipe16.0.pdf

To solve this issue, you need to downgrade the driver to the previous version. I had no issues with the 4.6.247.10 drivers so I used this one.

I created a PowerCLI script to verify the installed version of the net-be2net on all the BL460c Gen8 blades.

$be2netlist = @()
foreach($vmhost in (Get-VMhost | ?{$_.Model -eq "ProLiant BL460c Gen8"}| sort name)){
    Write-Host "Checking host $($vmhost.name)" -ForegroundColor Yellow
    $esxcli = Get-EsxCli -VMHost $vmhost
        $be2net = New-Object PSObject -Property ([ordered]@{
            vmhost = $vmhost.name
            driver = ($esxcli.software.vib.list() | ?{$_.Name -eq "net-be2net"}).name
            version = ($esxcli.software.vib.list() | ?{$_.Name -eq "net-be2net"}).version        
        })
        $be2netlist += $be2net
}
$be2netlist | ft -AutoSize

The output:

Now we wait for a fix from HP and Emulex.

BSOD in Virtual Machines configured with Intel Xeon E5-2x00v2 CPU’s


This article describes the Issue, the servers and BIOS version that are affected by this issue and the BIOS upgrade to fix the issue. I have also added a PowerCLI script to check if your HP servers are affected by this issue. You can find it at the bottom of this article.

Issue:

Download the BIOS upgrade for HP Servers and Blades here:

PowerCLI script:

update: PowerCLI script: compare dates fixed.

I created a script to see if the hosts are affected by this issue or not. The script will collect all ESXi hosts with HP hardware and the V2 Xeon processor installed. All those hosts are checked by Model, for instance DL360 Gen8. If the Model matches, the script will check the release date of the BIOS and returns a line of text in Red if the release date is older than the one mentioned in the HP Advisory: c04327904 or else a line of text in Green if the release date matches or newer than the one mentioned in the Advisory document.

vShield Host preparation: Host not reachable


Just a quick tip when you’re using vShield and want to prepare a new ESXi host. When you click on the vShield tab inside the vSphere client you might see the message “Host not reachable”.

image

So I started with some basic troubleshooting like ping from the vShield Manager to the ESXi host and from the ESXi host to the vShield Manager. This worked. The next step was the debug connection command from the vShield Manager appliance. This command completed successfully:

image

So what was the issue?? Well it’s simple the ESXi host was in Maintenance mode while trying to perform the Host preparation. This is not supported. The host needs to be in normal operation mode to be able to connect to vShield. Now I was able to prepare the ESX host:

Syslog gone mad after vSphere upgrade to vSphere 5.1 update 1


After upgrading a vSphere 5.0 update 2 host to vSphere 5.1 update 1 we noticed an issue with the lsassd daemon. Right after update manager finished with the upgrade the lsassd starts to write a lot of messages. Within the last 5 minutes the syslog server received 170K log messages from the upgraded host alone.

See the screenshot below:

image

The following message keeps popping up in the logs:

esxihost.domain.loc lsassd[9297]: 0x6eb11b90:Terminating on fatal IPC exception

To work around this issue you need to leave the Windows domain. Select the host – Configuration – Authentication Services – Properties. Click on Leave Domain… The excessive logging hast stopped immediately.

After that you can rejoin to the Windows domain again.

Import OVF/OVA: No datastore found on target in vCenter Server 5.1


I was trying to import an OVF/OVA template to one of my lab environments. But unfortunately this was not possible because of an error:

image

In this environment we are using Folders to organize the datastores. See the screenshot below:

image

This works for most of the time but when you want to import an OVF/OVA template you have to give up your folder structure to enable the OVF template. This is a small bug in vCenter Server 5.1. See KB2045635 for more details.

This is a small quote from the KB article:

This is a known issue affecting VMware vCenter Server 5.1.

Try one of the following workarounds:

  • Use vSphere Client to deploy.
    Open the vSphere Client and use it to deploy the OVA/OVF file.
  • Use Web Client to deploy.
    If the datastore is  in a folder, remove it from the folder and try to deploy.

In this case I had to move the SDRS cluster and the datastores attached to this SDRS cluster from the yellow folder to the root folder inside the Storage view of the vSphere web client.

Now I was able to deploy the OVF/OVA template.
