I'm fairly new to the storage game and wanted to ask a few questions just for reasurance before i go resizing LUNS that are currenlty in use.
We just setup a FAS3270 running 8.0.1P3 7-mode that is attached to a UCS Vsphere 4.1 environment. I carved out a 2tb flexvol with a 1tb LUN used for the vmware datastore. Well that was poorly planed because within the first month of moving servers to the new system we have quickly eaten up that 1tb.
My real concern being so new to the storage world is can i just go into the system manager and changed the LUN size from 1tb to 2tb on the fly? I know NetApp is famous for its resizing abilities but Im just uncoformtable changing the size with the LUN currently in use.
I have read all over the place that its ok and safe to change especially with VMware attached LUNs but i would just like to consult the oh so wise community before doing so.
