Hi,<br />
<br />
We current have a VMware 6.5 using a Dell Equalogic PS6000 SAN as the backend storage. Unfrotunatley we have two datastores that have extents that cover two physicaldevices, so I plan on vmotioning the vms off the datastore, delete and the recreate the datastore without the extent on the other storage device. On the SAN the storage is split into several volumes used for storage. When I have tested, I have deleted and recreated the datastore fine no problems, but on the volume on the SAN any used space within the new datastore has simply been added to the in se space on the volume. The SAN has no idea that the datatstore has been recreated (I assumed that the new datatstore would be able to use upto the in use space the volume thought it had before growing the volume). I'm guessing that my only option is to vmotion the vm's onto another datastore. Delete the datatstore and back end volume on the san. Recreate the volume on the san and then the datastore and then move the vms back?<br />
<br />
Cheers,<br />
Paul

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
