Issue

Secondary LUN can go to degraded state even though the relationship is not marked OOS

  • No out of sync seen from primary cluster
  • Ems logs on secondary cluster record the following :

[node_dst: scsit_lu_0: scsiblade.san.ssm.lu.degraded:alert]: LUN 819ea+WwyjM8 was marked as degraded due to a SnapMirror Active Synchronous relationship going out of sync.
[node_dst: scsit_lu_0: scsiblade.san.ssm.lu.online:notice]: LUN 819ea+WwyjM8 is back online.
