IT44674: VOLUME DELETED ALERTS DO NOT OCCUR CONSISTENTLY FOR EXPIRING SAFEGUARDED COPY BACKUP VOLUMES

APAR status

• Closed as program error.

Error description

• Storage Insights can generate alerts for deleted volumes, and it
  is normal for Safeguarded Copy backup volumes to be deleted.
  However, Storage Insights does not consistently generate alerts
  for the deleted backup volumes.  Some backup volumes have a
  corresponding volume deleted alerts while others do not.

  Additional details:
  
  1. The SafeGuarded Copy technology at the center of this
  APAR is now considered "old" technology (referred to as
  SGC 1.0).   We suggest customers now use the new
  SGC 2.0 technology with Policy Based Replication and
  Volume Group Snapshots to implement their SafeGuarded
  Copy work.
  
  2.  If the customer continues using the SGC 1.0
  technology, we suggest that customers migrate the data
  collection for the relevant storage devices from Data
  Collector to Call Home With Cloud services for a better
  experience with regards to receiving alerts in Storage
  Insights when SafeGuarded backup volumes are created
  and deleted.
  
  3.  With the resolution of this APAR, alerts are now getting
  triggered for the deleted SafeGuarded backup volumes as
  soon as the mini-probe occurs, except in the following
  situations:
  
    a.  When the storage device created the SafeGuarded
  backup volumes but did not delete the existing SafeGuarded
  backup volumes yet by the time Storage Insights ran a
  mini-probe.
  
    b.  If the SafeGuarded backup happens when the storage
  device had already sent a bellwether on storage volume, and
  it did not cool down yet.
  
  In these two cases, there will be a delay in Storage Insights
  updating those volumes and triggering the alert.  And Storage
  Insights cannot do anything about that delay ... hence the
  recommendation to migrate from Data Collector to Call Home
  with Cloud Services.
  

Problem conclusion

• The fix for this APAR is targeted for the following release:
  
  IBM Storage Insights 3Q24   [ 54X-IBM-SI ]
  ( release target 3Q 2024 / July )
  
  The target dates for future releases do not represent a formal
  commitment by IBM. The dates are subject to change without
  notice.
