It's in RAID5, we already have 4 disk in it. 1 is a spare.
01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05)
with 4 disks.
Question: How can we put in additional storage to it? After a new disk is attached to the HW card, what are the steps so that the OS will recognize it?
