After adding new disks to a controller you might come across an error about Max Raid Size Group
Default Raidsize group depends on size of disk but this will be 16 , FYI – The maximum RAID group size is 28
There does not seem to be an easy way to do this via GUI
Open Cluster Shell , enter the following to get into Aggr Options
Show your existing maxraidsize
aggr show -fields maxraidsize
Change the Value
