folks, I'm reasonably newbie at vmware. I have created a vm exchange 2010 mailbox server. which setting should the disks be set to in terms of the Independant and persistent setting.
My gut feeling is that theses disks should be set to Independant, Persistent.
Is this correct?
Appreciate any comments from the wise VM'ers.

Hi R-R
I dont see an option for normal disk. This is Vshere 5 and I am right-clicking to edit virtual machine then add hard disk. So I have the other setting which is to not use Independant - Persistent. Ill check the docs.

The Default for a VMware virtual disk is not selected.

If you set Indepented Persistence you will not be able to use VMware Snapshots, which may prevent VMware Backups, if using VMNware API Backup Software e.g. Veeam Backup and Replication

Independent should not be selected as it will create issues in DRS as well (not sure if you have DRS configured).  Just deselect that option and let the disk remain with the virtual machine.

Ok I thank everyone, being a newbie pramod, what is DRS? Secondly, pramod, I'm concerned specifically with Exchange 2010 function. If I shutdown via exchange guest will it handle LOgs and exchange database functions OK? I dont want to loose data if for instance the host dies or even guest dies. It seems to me that the best is to write data immediately to disk?? Does this happen?

If you shutdown the database and logs should be fine.
