I need a little help about raid group resizing.
I've a 2020 storage with one controller and 12 pc 300SAS disks
I created one aggregate with 11 disks and 1 hotspare.
Now I bought a shelf with 6 pc FC 300 disks to increase aggregate capacity.
The RAID group size 3-16 disks but in SAS-FC environment the max number is 28.
Because of that there are 2 spare disks but one enought for me.
In spite of that I cannot increase the disks number to 17.
Is it command line force option or something
The doc does say 28 is the max. I have never done this so do not know if it will work.
You can customize the size of your RAID groups based on your requirements for data availability, performance, and disk utilization.
You change the size of RAID groups on a per-aggregate basis, by setting the raidsize aggregate option. You cannot change the size of individual RAID groups.
The following list outlines some facts about changing the raidsize aggregate option:
Enter the following command: aggr options aggr_name raidsize size
The following command changes the raidsize setting of the aggregate aggr3 to 16 disks:
aggr options aggr3 raidsize 16
Yes I've read that. Unfortunately when I've tried I've got an error message.
Invalid size. It had to be 3-16. I've reached 16
