  • ActiveIQ Unified Manager (AIQUM) 9.6+
  • ONTAP 9
  • SnapMirror

Issue

  • AIQUM reports alerts Mirror Replication Lag Warning every X hours 
  • The actual SnapMirror relationship uses a larger value for the schedule than the warning
    • For example:
      • Lag warning in AIQUM is coming every 2 hours
      • Lag warning threshold is set to 150% 
      • The schedule is set to 2 hour interval in SnapMirrror 
      • Therefore, 150% should be 3 hours 
  • AIQUM is not calculating the warning and error threshold values correctly for SnapMirror relationships
  • AIQUM au.log shows: 
    WARN  [foundation-poll-2] c.o.s.a.d.n.t.z.ZAPIConnection (ZAPIConnection.java:729) - [netappfoundation] <cluster_fqdn> - <cluster_fqdn> <cluster_fqdn> - Ignoring failed zapi: job-schedule-cron-get-iter; errno: 13115, reason: Invalid value specified for "key-0" element within "job-schedule-cron-get-iter-key-td": "<stale_cluster_uuid>"
  • Running job schedule show in ONTAP shows some schedules with cluster name as a stale UUID instead of the proper cluster name
    > job schedule show  -fields cluster,description
    cluster                              vserver   name              description
    ------------------------------------ --------- ----------------- ------------
    <stale_cluster_uuid>                 <vserver> <schedule>         <schedule_description>
    <stale_cluster_uuid>                 <vserver> <schedule>         <schedule_description>
  • In System Manager, Protection > Overview > Local Policy Settings > Schedules
    • Some of the schedules have a blank schedule
    • When trying to edit these schedules it will just load forever in the GUI and will not load anything
