Add/Extend Datastore

Jump to solution

Hi,

I have added 2 new drives internally to my ESX's (VI3 3.5/VC2.5) raid 5 array and i would like to either make the datastore 'storage1' bigger or add a new datastore with the new space. My preference is to increase the size of the existing datastore.

I have gone into the configuration tab, chosen storage, and then properties. I see that there is an 'Add Extent' button. The insturctions seem to indicate that this will do what i want. When 'Add Extent' dialog option opens it starts in the 'Extent Device' step. There is an area on the screen for a list of devices; but this list is empty. There is an input box that says 'SAN indentifier'. I don't know how to proceed. Can someone please assist me.

Thanks,

Fred

In order to add an extent to your existing datastore, the space has to be presentd to the ESX host before it will show up as available to add as an extent. If you make the RAID5 array larger, then you'll have to take the enlarged space, and create a partition out of it, as it will not automatically be recognized as available for use. One you partition it, and configure it with fb as partition type, you should be able to add it as an extent.

Technically speaking, it is not recommended to add extents so design it with best practices. You should have other options besides adding extents, so what are you trying to accomplish?

azn2kew,

I was trying to increase the size of my datastore or add a new datastore. I ended up adding a new datastore. Please elaborate on what you mean by "best practices". I'm asking the question because I don't know the best practices and telling me that doesn't end up helping. If you have a link to a document or have some best practices advice i would be happy to see this information so taht I can learn to better utilize my ESX system.

Thanks for your comment and willingness to pitch in on my question.

Fred
