Generally, you administer a node that is using root-data partitioning the same way you administer a node that uses only physical disks. However, partitioned disks are displayed slightly differently, and you need to take their presence into account for some management tasks.
Root and data partitions are used by the RAID subsystem the same way that physical disks are, and the same requirements and best practices apply. You follow the same best practices for spare management, and disk names are not impacted by root-data partitioning.
When you are working with a node that is using root-data partitioning, the following tasks are slightly different:
Spare partitions are displayed differently—as either root or data. In addition, you need to ensure that a root and data spare are provided on the same disk to support core file creation. Finally, you should understand whether you are mixing physical disks and partitions in the same RAID group, and the impact of doing so.
Partitioned disks display shared for the Position column, rather than their RAID disk type.
Automatic ownership assignment works for partitioned disks. If you need to manually assign or remove ownership for partitioned disks, you must do so for both partitions as well as the container disk.
Removing a partitioned disk can potentially affect more than one aggregate.
