Applies to

  • MetroCluster IP
  • AFF-A300
  • Advanced Disk Partitioning (ADP)
  • ONTAP 9
  • Unusable partitions sizes after shelf expansion

Issue

Different ADP layouts are observed to be in use at both sites.

 

Example:

Aggregate siteA_aggr_n1_root – Partition size: 53.88GB

  • 8 data partitions
  • 1 parity partition
  • 1 dparity partition

RAID group /siteA_aggr_n1_root/plex0/rg0
