Why is a newly added disk not auto-partitioned on ADP systems?
Applies to
- AFF Models
- FAS Models
Answer
Non-MetroCluster Environments
When a disk drive is replaced and assigned to a node in an ADP configuration the disk will remain as a whole disk (unpartitioned) until one of the following operations happens:
- Disk Reconstruction of a disk containing partitions
- Rapid RAID Recovery (also known as Sick Disk Copy) of a disk containing partitions
- Aggregate Expansion with additional disk partitions added into an existing or new raidgroup
- While correcting misaligned spare partitions
- If a drive is manually partitioned
If the auto-partitioning fails with a timeout message during any of the above operations, Data ONTAP will automatically attempt to partition the same or another similar drive when available.
MetroCluster Environments
ADP configuration behaves differently in MetroCluster environments. Review the following for more details:
