Re: No. of disks in a LUN
According to the guru's that designed the VA, you are NOT ALLOWED to know how it works --- just accept it!

Re: No. of disks in a LUN
There are 2 Redundancy Groups (RG's) - RG1 and RG2. RG1 consists of all the drives in odd-numbered slots (1, 3, 5, 7, 9, 11, 13, and 15) in the disk chassis'. RG2 is all the even-numbered slots (2, 4, 6, 8, 10, 12, and 14).
All LUNs have an assigned RG. You specify the RG when you create the LUN. Every LUN spans ALL of the drives in the RG.
So, if you have 30 drives in 2 chassis (base plus 1 expansion) then RG1 has 8 disks per chassis, or 16 disks, and RG2 has 7 per chassis, or 14 drives.
Any LUN on RG1 has 16 drives in it. Any LUN on RG2 has 14.
Good luck!
