I will explain the use of the vicfg-cfgbackup command using a guided scenario:
I have a vSwitch named vSwitch1 in a ESXi host for my lab.
The first step is to make a backup using the option “-s”:
Then I remove the vSwitch1 as you can see in the images below:
vicfg-cfgbackup_Remove vSwitch1 (2)
And finally, restore then I restore the configuration using the option “-l”:
It is important to know the strange behavior of the restore command. If you have the target host into maintenance mode, the restore process will fail. The process itself puts the target host into maintenance but doesn’t check if it is already in this state. In the image below I put the host into maintenance mode using the command vicfg-hostops and then try to run the restore command. It fails saying “The operation is not allowed in the current state”. Exiting maintenance mode, using vicfg-hostops again, i can run without problems the restoration:
Read, read and read and then practise, practise and practise…
The past November 30th I passed my VCAP-DCD exam,
I can’t say anything about the exam but I can say you how I did prepared to take the exam:
The percentage is the amount I read/studied the book. 20% means I read the book about 20%.
For some weeks ago we had in the company’s vCenter a broken plugin (HP Insight). As there was not a major problem I forgot about it until a few days ago.
Googling I found the way to delete it: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1025360
A few days ago I found a extremelly useful application: RVTools (http://www.robware.net/).
RVTools allow to access ALL the info you need from a grid style view:
And you can export to Excel the tabs seen in the previous screens:
Hello RVTools, bye-bye Custom-PowerShell-Scripts!
Researching the Internet for info about VCAP v5 (both DCD, DCA) certifications’ I found LabGuides.com, a site where you can get the guide, the vApp, and the links to the software you need to mount a virtualized lab for VCP5 and VCAP-DCA5.
