Perf Charts service experienced an internal error in vCenter

After a long summer break I’m back with a new post 🙂 Today one of my customer got an error in vCenter performance monitor for all there hosts. “Perf Charts service experienced an internal error in vCenter message report application initialization is not completed successfully. retry in 60 seconds” So I found this KB from VMware that says you have to restart the VMware VirtualCenter Management Webservices service. This did not help at first. Then I could see that the SQL Server Browser service was not running I then changed the startup type to Automatic and the started the service and then I restated the VMware VirtualCenter Management Webservices service again. Now the performance monitor is working again! 🙂 If you have anything to add or just fund this usefull then pleas leave a comment below. Thanks!

Vmware Storage CLI Commands

This is a post on some of the Storage CLI commands you can use. I will try to updatedate this post as I finde more usefull ones. 
The ‘DF -h’ will list all the Filesytem, Size, Used, Availavle, Use % disk space on all your datastores
 The VFD -h will show you how much disk space is free the ESX(i) has free, this can be useful if you are going to update the ESXi installation.

Removing old LUN connections from vSphere host

Today I had a problem with a host that could not restart the management agent, it just hung at the starting agent in the console. I tried to restart the /etc/init.d/hostd restart and /etc/init.d/vpxa restart commands form a ssh prompt, but no dice. I looked in the system logs and found that there was some problems with connectivity to some LUN from an old storage box that was detatched some time ago. Using SHH the only way to communicate with the host I ran this command : esxcfg-mpath -L | more the output showed that some of the LUNs connections was in the state of dead! Then I ran esxcfg-rescan vmhba5 the storage services will now refresh its connections on each LUN. This can take some time, depending on how many LUN you have. I hope this can help when you are discarting LUNs 🙂

Failed to connect to VMware Lookup Service SSL certificate verification failed.

When installing the VCSA on a network with DHCP your VCSA will get an IP from the DHCP as it’s configured to use DHCP out-of-the-box. This however will give you some trouble down the road. If you start the confingur the VCSA with the DHCP IP you will get an error when trying to connect to the vSphere Web Client. Something like: Failed to connect to VMware Lookup Service https://:7444/lookupservice/sdk – SSL certificate verification failed. The VMware KB artikel 2033338 suggest that changing the certificate will do the trick. But I found that when you install the VCSA and boot it for the first time, disconnect the network will resulting in not IP for the VCSA 🙂 Then you can change the DHCP default to a static IP by logging in to the appliance (default user root and password vmware) and using /opt/vmware/share/vami/vami_config_net command to configuer the IP. After setting the static IP, Gateway ect. connect the VCSA to the network again. You can now go the http://your-vcsa-ip:5480 and start the config wizard and your vSphere web client will work!

Place an ESX Host into maintenance mode using the command line

Okay this is not new and you can find it all over the net, but for my own reference (and yours ) To enter maintenance mode use: vmware-vim-cmd /hostsvc/maintenance_mode_enter To exit maintenance mode use: vmware-vim-cmd /hostsvc/maintenance_mode_exit To check if a host is already in maintenance mode: vmware-vim-cmd hostsvc/hostsummary|grep -i maintenance It will return : inMaintenanceMode = false

Micro review of the VMware vCloud: Design Best Practices course

Okay so the course is designed to guide you through the fases of designing a vCloud. That been sayed the book on the course are based on version 1.5 and there by out of date from the first day. Lucky for me the instructor (Bruce Watson) was up to speed on all 5.1 drifferenses in respect of vCloud design. All in all it was a okay course, it covert all the outlines that was listed, but not a must have for the VMware Certified Advanced Professional – Cloud Infrastructure Design (VCAP-CID). You will be better of reading the vCAT.
