Hi dkmartin,

I'll reiterate, there is a dependency on the backend configuration.

If you have a requirement to slice and dice a 1Tb LUN, you'll end up (from your comments) /dev/sda1, /dev/sda2, /dev/sda3 etc....... These would then be used for the "rootvg", the "appvg" the "dbvg" or any other way that you decide to apportion the disk.

If you decide to go for individual LUN's then you would have effectively a "ROOT_LUN", an "APP_LUN" and a number of "ORACLE_LUNS" for things like redo, archive, table space and all the other bits of an Oracle Instance - basically whatever your standard build is.

Without knowing what the backend storage is and how it is configured, how the storage is managed and how it is tiered are the arrays intelligent along with a miriad of other requirements it isn't possible to be any clearer with the information.

At the back end this could be all on one physical disk (You don't want that) or it could be spread over many physical disks.

For simplicity of management a single LUN is good, if the I/O on the VM will allow you to do that without impacting performance.

As to this being "configuration advice" it is not, there is no way that any advice could be given based on what you have told me - the sum total of the knowledge inparted by yourself is that "It's currently AIX and it's moving to Linux on VMware - the LUN mentioned is 1Tb and you use Oracle".

Oh! and it won't be using ASM.
