Applies to

  • FAS2554
  • ONTAP 9
  • Advanced Disk Partitioning (ADP)

Issue

  • The disk Shelf 0 bay 4 has failed, so replace the new disk, but not recognize.
  • The RAID group "n1_aggr1" has degraded and neither the existing spare disks in pool0 nor the new disk cannot reconstruct. 

Example of node-2 sysconfig -r:

Aggregate n1_aggr1 (online, raid_dp, degraded) (block checksums)
      Plex /n1_aggr1/plex0 (online, normal, active, pool0)
        RAID group /n1_aggr1/plex0/rg0 (degraded, block checksums)
