I recently bought FAS2020 with 12 x 1 TB Disks.
Capacity is the most critical factor and we configured FAS 2020 as shown below.
Controller 1
raid 4 with 2 Disk( 1Parity+ 1Data) for aggr0
Controller 2
raid 4 with 10 Disk( 1Parity+ 8Data +1Spare) for aggr0
But in controller 2 it is creating 2 raid group (rg0 & rg1) as shown in blue color.
Kindly suggest a solution to make a single raid group for aggr0 in controller 2.

aggr create aggr1 -r 9 …
see aggr command description for all options. You will need to destroy and re-create aggregate, it is not possible to remove raid group. For SATA disks default raid group size in 8.

Thanks aborzenkov for suggestion
How many disks including spare disk can accomodate in raid 4 group for FAS2020.
I am just a beginner in Net App product.
Kindly let me know whether i could configure as below
Controller 1
raid 4 with 2 Disk( 1Parity+ 1Data) for aggr0
Controller 2
raid 4 with 10 Disk( 1Parity+ 8Data +1Spare) for aggr0

Yes, that’s technically possible, although running without spares is not recommended.

Oh, I am awfully sorry, I completely missed the fact that you are using SATA disks ☹
In this case raid group size is limited to 7 disks, you cannot increase it. What you can do is to create RAID_DP without spares (although as mentioned running without spares is not recommended). Default raid group size for RAID_DP is 14 disks.
