  • ONTAP 9
  • SnapMirror active sync (SMas)
  • Consistency Groups
  • FC
  • iSCSI
  • ANDU process
  • ESXi host

Issue

  • Controller does not fully come online during ONTAP upgrade or takeover/giveback operation:

cluster::> ::> storage failover show
                              Takeover
Node           Partner        Possible State Description
-------------- -------------- -------- -------------------------------------
cluster-01  cluster-02  true     Connected to cluster-02, Partial giveback
cluster-02  cluster-01  true     Connected to cluster-01. Waiting  for cluster applications to                                        come online on the local node. Offline applications:scsi blade.

  • Upgrade on Node2 completed, however Node2 was not completely given back by Node1
  • Only Controller and root aggregates were given back to Node2 but the data aggregates still were on Node1, as the cluster applications on Node2 did not come online due to SCSI blade being offline on Node2
  • All the FCP LIFs on Node2 are in down state as the SVM on Node2 is stuck in initializing state
  • Since Node1 is holding the data aggregates of Node 2, ANDU on Node1 is in paused state
  • Aborting the SVM initialization helped complete giveback of Node2, but SVM stays in initializing state and FC LIFs on Node 2 are still down
  • SVMs on both the nodes go into initializing state and the FCP LIFs are operationally down if second node is taken over
  • SAN SMBC cache to be initialized or Waiting for the SAN SnapMirror active sync cache to be initialized errors in bcomd log:

  • Test SMas relationships created on this source cluster were in out of sync state
