The extra data partition in the root-data-data version doesn't really change the disk assignment guidance for the physical (container) disks in an AFF system. We're still say saying half of the shelf is owned by node 1 and the other half is owned by node 2.
Hi Andris, the KB article seems to talk about the advanced disk partitioning with 2 partitions, not the newer enahnced ADP 3 partition layout. I've been looking for some more documentation on the 3 partition layout but can't find any links or sections in the 9.1 documentation. Would you have a KB or documentation link for it ?
The container partition (the disk itself) is assigned to one node. The data partitions are assigned to both nodes, so one node owns the root partition and one data partition, while the other node owns the second data partition.
Thanks for the info. The customer has 40 partitioned disks, when we want to add 8 more disks to the system how can we set these disks as partition. As far as i did not find anything except initializing the system. But the system is in production.
