vCenter 5.1 Web Interface Show Incorrect RDM Sizes

I noticed a odd issue in our vCenter 5.1 GA web interface (I know we are on a old version and planning to upgrade to 6 when update 1 is released) On a VM with a RDM the web console shows one size as an example 800GB. When in fact the LUN is really 1.3TB.  The Guest which is Widows 2008 R2 see the drive as 1.3TB. So what gives?? I cannot see the RDM sized in the fat client, I restarted all vCenter services and it did not help. Any suggetions

You could try restarting  Web Client, vCenter Server, Inventory Service, if this has got the duff information in it.

Was the RDM ever re-sized ?

5.1 GA is very old,  (9th October 2012!)

I see, you ontop of your updates!

we've had 6.0.0b!

Yes, I suspect, Inventory Service has not picked up the change.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Mr TorturSystem EngineerCommented:
why can't you see the RDM size int he fat client? Because you cannot access the VM edit settings menu?
You could try to update your vsphere (fat) client on your computer (not on vcenter) as we got rid of that accessing "issue" in lasts 5.5 fat client versions ; but if you are on v5.1 it is not sure it will work.

I did restart the Inventory serivce and it did not help. Regarding the fat client when I go to edit settings on the VM may be I am being stupid and not looking in the correct place

Right Click VM > Edit Settings > Disk Properties ?

The issue with not be able to Edit/View VM Settings was with Virtual Machine version 10 virtual machines, which only exist, in 5.5!

Originally intended by VMware to "force" users to use the Web Client, but later VMware decided this was a bug and would fix in the latest version of the 5.5 client.

BUT, although you can view settings of a virtual machine version 10, you cannot add or edit any virtual machine version 10 settings/functions/devices.
Mr TorturSystem EngineerCommented:
ok Andrew sorry for that mistake, you're right this "political issue" appeared because of vm hardware 10 in 5.5. But also I did not remember that correctly I think I was able to modify a v10 VM settings with last 5.5 fat client version.. Maybe another memory mistake, I am not that old however...

Also this is another subject but this KB seems to tell we can modify some settings in hardware version 10 VM, no?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
You can modify the non-virtual machine 10 settings!

BUT, be careful if you have virtual machine version 10 VMs, best to manage and change/edit with Web Client, because the vSphere Client, can drop settings from the configuration file it does not understand.

To be honest, only use virtual machine version 10/11 if you require the features!
Mr TorturSystem EngineerCommented:
Ok, thanks for the info.

Sorry for the late response everyone..

The host is running ESXI 5.1 does VM hardware 10 is not even an option.

I am just puzzled why after increasing and RDM size which was picked up by the guest OS with out issue. Vmware on the Editing setting page still shows the old size even after restarting the services.

Also  this may or may not be relate but in the summary page of a random VM the provisioned space it twice the amount of the used space yet the VMDK / hard drive is only 25GB and there are not snapshots in place.  Please see the attached screen shot. It is very odd and throwing off my storage reports.

I found this article but hoping not to remove from inventory and readd a large number of running VM's. Why does this happen?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Correct ESXi 5.1 only up to version 9!

Inventory refresh broken! - it happens!

Is it causing Product Issue?

is it causing a Service Outage - ?

Spend some time, doing capacity management and performance monitoring!

or planning that 6.0 upgrade!
