Issue

  • During resillience testing following is observed when performing switchback:
Cluster_A (manual recovery required): Some disks were left behind during switchback. They are listed along with a reason for failure: 2.11.15 (no error)
If any of these disks are failed, replace them. Otherwise use the "metrocluster switchback" command again to return the disks to their original owner. Use the "storage disk show -dr-home-id !- -fields dr-home, container-type, aggregate" command for more details on the status of the left-behind disks.
 
  • The internal disk is missing path from partner node node_A_2

Cluster_A::> storage disk show -disk 2.11.15
