I have a AFF300 with Ontap 9.3P5, it was delivered with a full shelf of 3.8TB SSD's. The system has root-data-data partitioning. After 6 months as our VMware storage we need extra headroom. So I have aquired half a shelf of 3.8TB.
But I can't seem to find a way to get them partitioned in the same manor. I assigned them to node1 via :
cluster1::> storage disk assign -disk 1.2.* -owner node1
I have tried to use:
cluster1::> storage disk assign -disk 1.2.* -owner node1 -data1 true
Error: invalid argument "-data1"
I can't seem to find where to get this fixed. There is one spare disk which has the correct root-data-data partiotion, can this disk be used to force raid-grp creation?
I would like to spread the load between the 2 nodes. If I use the full disks node1 will have approx twice the load of node2.
Root-data-data partitioning supported with up to 48 drives. Therefore, you should be able to do it.
Assign your physical disks to controllers and then add them to your aggregates without trying to partition them first. The system should partition them for you automatically, while you add them to an existing aggregate.
Use -simulate true argument first, to check the system going to do it properly and as you expect.
Just to make sure:
NetApp recommends having all the RAID groups in your aggregate with the same disk size except for the least one. In the last RAID group should be at least half of the size of the previous RAID groups. I.e. if you have one aggregate consisting out one RAID group (23 drives: 21 data + 2 parity) then you should add to next RAID group at least 12 SSD to make your last RAID group no less than half of previous.
And it looks like you should meet those requirements. Just to clarify, do not add just 3 drives to the new RAID group with existing 23.
