Hi, To use RDM there is specific reason, like MSCS clustering ..... Here is link which shows performance difference between vmdk and VMFS , even though there is no much diference...

One more thing is there a quick way to update file system from vmfs 3 to 5 i.e can you use update manager or is this a manual process that must be done

Once all hosts with access to the VMFS volume are updated, you may upgrade your VMFS datastore(s) from "Configuration" -> "Storage" by clicking the Upgrade link for each datastore. This can be done...

Hi,Yes. Normal vMotion is possible and we are able to do the vmotion without any problem. Datastore is shared across all the hosts. Able to do the storage vmotion for few powered on machines and some...

Thanks for your inputs, but I have resolved it. A bit of a "schoolboy error", but although I had added the VMKernel IP's into the root host and read/write host into the NFS Export properties, I also...

Hello all, I have a SQL server on a volume that has 184GB free out of a total 1TB. I need to add an additional 150GB drive to the VM but really didn't want to have to create a new datastore since it's...

You could do this. The alarms would need to be addressed for sure. Check out VMware KB: Troubleshooting a datastore or VMFS volume that is full or near capacity for info on the free space requirements...

So if I have 34GB or so free I may be ok? I don't know, I think I may just create a new larger datastore and svmotion it to it. I was going to create a consistency group on the SAN for replication,...
