This should be really simple with 2008. Simply give the disk more space within vCenter and then expand it from within the OS. Here is a KB article on expandng disk. http://kb.vmware.com/kb/1004071

I have shutdown the server > edit settings but can't change the size of the hdd.

Does your account have permissons to make those types of changes? If the guest is powered off you should be able to edit the boot disk.

Converter would always work but seems like so much trouble for something that is so simple. Do you have another account to try it with?

Hi

1st Step : Go to virtul machine (Guest machine) setting>Increase the harddisk size (give required space, ensure the space available with your LUN or local disk you are using as a datastore)>apply.

2nd Step : Windows machine console go to compuer management>diskmanagment>check the disk available with your system drive as unpartitioned

3rd Step : download tools like diskpart and keep it in your system drive

>open command line console>give the path of diskpart.exe and run--> it will ask adding space.

check your system drive ;;

thanks

@ satishgfe again Smiley Wink

you should really read the posts completely before answering - not always the necessary input is already mentioned in the first post.

@mnisadmin

do you have snapshots ?

Your VM may have snapshots. If you delete those, then the disk size won't be greyed out when you shutdown the VM. After you get rid of the snapshots you should be able to re-size the disk.

Rich is right, check the snapshots. Assuming your vCenter logon acct has permissions and the VM is shutdown you can edit the disk size right where your screenshot is. You can then extend the drive using diskpart in Windows.

Converter will work to, but its overkill for what you are doing. Converter is nice because its the only way I know of to shrink a drive volume, which is useful when migrating a physical server to a VM and it's been assigned way more drive space than it needs.
