The SAN I had available to do this on, is the Promise VessRAID 1830i
NOTE: Your interface to your SAN might look different, but the terminology stays the same.
1. Creating the storage LUN on the SAN�
Login to your SAN interface, and create a new logical drive / LUN (whatever your SAN calls it)
For the purpose of the tutorial, I created a LUN of 500GB in space, in RAID 5 configuration.
My SAN asks if I want to edit lun mapping (Masking), once a LUN is configured. I always mask luns, as I want devices to only see the LUNs they are entitled to. I clicked “OK”
