Applies to

  • ONTAP 9
  • Manually upgrading AFF or FAS controller hardware using Aggregate Relocation
  • Flash Pool aggregate(s)

Issue

  • Hardware controller upgrade using manual aggregate relocation (ARL) procedure:
  • After the first node has been successfully upgraded, during aggregate relocation to new node hardware in preparation for the second node upgrade, Flash pool aggregate goes offline and command fails:

Cluster1::*> storage aggregate relocation start -node Cluster1-02 -destination Cluster1-01 -aggregate-list node2_FP_aggr1 -ndo-controller-upgrade true

Cluster1::*> storage aggregate relocation show

Source         Aggregate  Destination   Relocation Status
-------------- ---------- -----------   -----------------
Cluster1-01
               -          -             Not attempted yet
Cluster1-02
               n2_FP_aggr1 Cluster1-01  Failed: Destination node did not online the aggregate on time.

  • The RAID groups containing the SSD Flash Pool disks go missing from sysconfig -r output.
