VMware: Host IPMI System Event Log Status alarm is triggered repeatedly in VMware vCenter Server

January 22nd, 2015 2 comments

Solution

To resolve this issue, stop the alarm from triggering repeatedly and clear the IPMI System Event.log file and reset the sensors.

To clear the IPMI System Event.log file and reset the sensors:

  1. Open vCenter Server using vSphere Client.
  2. In the vCenter Inventory, select the ESXi/ESX host.
  3. Click the Hardware Status tab.
  4. Click System Event log under View.
  5. Click Reset Event Log. The red alert is removed from the System Event log.
  6. Click Reset Sensors to reset the host sensors.

Introduced in ESXi 5.1 Update 2 (Build Number: 1483097) and ESXi 5.5 Patch 1 (Build Number:  1474528), there is a new localcli command line to clear the IPMI SEL logs:

localcli hardware ipmi sel clear

To run localcli command on the ESXi 5.1 or 5.5 host:

  1. Connect to the ESXi host via SSH. For more information, see Using Tech Support Mode in ESXi 4.1 and ESXi 5.x (1017910).
  2. Run this command:
  3. localcli hardware ipmi sel clear

VMware: Update or recover “root” password using Host Profiles

August 26th, 2014 No comments

Start Profile Wizard after you have entered Maintenance Mode

image

– Select: Create Profile from existing host

 

image

– Select host (in maintenance mode)

image

– Profile details: Reset root password

image

– Finish the host profile creation
On the left pane select your new host profile and right-click and select edit profile:

image

– Select: Root password reset > Security configuration > SSH authorized key for root user

Note: check or deselect specific host profile configurations to enable or disable them. A disabled configuration will not be applied when applying the host profile and hosts will not be checked for compliance with that configuration

Now click OK and we’ll start attaching the host of which we want to reset the password. Click ‘Attach Host/Cluster’ and select the right host, click Attach and then OK.

Voila, the root account of the host has been reconfigured and you should be able to log in again. Now the only thing left is to detach the host from the profile.

VMware: Cannot remove a License Key from VMware vCenter Server

August 23rd, 2014 5 comments

Last week I upgraded a vCenter Server from version 5.1 to 5.5, I also added a 4th hosts to the cluster, so I need to upgrade the host license keys. But after upgrade I couldn’t remove the license files in vCenter Licensing section:

Solution:

To connect to the ADAM database:

  1. Log in to the vCenter Server.
  2. To open ADSI Edit, click Start > Run, type adsiedit.msc, and press Enter.
  3. Right-click ADSI Edit and click Connect to.
  4. In the Connection point section, click Select or type a Distinguished Name or Naming Context.
  5. Enter dc=virtualcenter, dc=vmware, dc=int
  6. In the Computer section, click Select or type a domain or server: (Server | Domain [:port]).
  7. Enter localhost
  8. Click OK.
  9. Drill down to DC=virtualcenter,DC=vmware,DC=int, OU=Licensing, OU=LicenseEntities.You see the CN="license key" containers.
  10. Right-click the container that shows the the serial number of the key that is negative within the vCenter Server Licensing page.
  11. Click Delete.

Result:

When you restart he vSphere client and navigate to the Licensing page the old license keys are removed and you can re-assign license keys to the hosts

VMware: Service ´VMware Kdc Service’ (VMwareKdcService) failed to start

August 13th, 2014 No comments

Last week I upgraded VMware vCenter server from version 5.0 to 5.5 Update 1c, during installation of vCenter Single Sign-On 5.5 I received this warning message:

Service ‘VMware Kdc Service’ (VMwareKdcService) failed to start. Verify that you have sufficient privileges to start system services

 
image

 

The service account which I´m using for the upgrade is Domain Administrator, I tied to start the service manually but the service won’t start. The Windows Event log was clean, but in the vmkdcd.log file (located at: C:\ProgramData\VMware\CIS\logs\vmkdcd) I found this error logs:

20140812092452.000:[email protected]:TRACE: Vmkdcd: stop
20140812092458.000:[email protected]:TRACE: VmKdcSrvOpenServicePortTcp called…
20140812092458.000:[email protected]:TRACE: dwError=87 errno=17
20140812092458.000:[email protected]:TRACE: VmKdcSrvOpenServicePortTcp done.
20140812092458.000:[email protected]:TRACE: ERROR: vmkdc VmKdcInit failed (87)

20140812092458.000:[email protected]:TRACE: Vmkdcd: stop
20140812092503.000:[email protected]:TRACE: VmKdcSrvOpenServicePortTcp called…
20140812092503.000:[email protected]:TRACE: dwError=87 errno=17
20140812092503.000:[email protected]:TRACE: VmKdcSrvOpenServicePortTcp done.
20140812092503.000:[email protected]:TRACE: ERROR: vmkdc VmKdcInit failed (87)
20140812092503.000:[email protected]:TRACE: Vmkdcd: stop

 

Solution:

To resolve this issue, ensure port 88 is available for use by the VMware Kdc Service:

  1. Use netstat from an elevated command prompt on the Windows host system to confirm port 88 is not in use. For more information on using the netstat command, see Determining if a port is in use (1003971).
  2. If another application is using port 88, reconfigure or disable the application to open port 88 for use with the VMware Kdc Service.

In my case VMware Converter Standalone Server was running and configured at port 88, I removed the installation and restarted the Single Sign-On setup.
