Hello experts - I need to reconfigure storage on my SAN/VMware environment and could use some guidance. My environment consists of the following:
A single Netapp FAS2240-4 currently divided into six 1.9TB luns, three on the top controller and three on the bottom.
VMware Vcenter 5.1 with 14 virtual machines using the existing Netapp LUNS
I'd like to combine two of the 1.9TB LUNs into one larger LUN to expand capacity on my Windows 2012 file server. I've migrated all of the VMs from LUN1 and LUN3 on the top controller so they are now empty with the exception of a folder called .vSphere-HA.
First, I want to be sure that I can actually create a LUN that large for my version of VMware and that once I migrate the file server to it, that I can then continue to expand the existing drive which is currently at 1.5TB. I keep seeing references to a 2TB limit but I'm not clear on exactly where that comes into play. If I am in fact able to make full use of the larger LUN to expand the existing drive then my best guess as to how this would work is as follows:
1) Unmount LUN1 and LUN3 in Vcenter
2) Set each LUN to offline mode from the Netapp OnCommand System manager
3) Delete both LUNs
4) Create a new LUN from the newly available space
5) Add the new LUN to Vcenter
6) Migrate file server to new LUN
7) Extend drive
I want to be sure I'm not missing steps or planning this incorrectly so any feedback would be very much appreciated, thanks!
