IT45487: FALSE POSITIVE CAPACITY ALERT NOTIFICATIONS RECEIVED

APAR status

• Closed as program error.

Error description

• Storage System Used Capacity alerts meant to notify the user of
  disk space reaching a specific limit within a certain number of
  days are being generated even when there has been no capacity
  growth on the system for past 1 year.  Capacity value is above
  the threshold, but its value is not changing.  This is being
  viewed as a false positive.
  
  Used Capacity	>= 80 % In next 30 Days	  Critical
  Used Capacity	>= 75 % In next 90 Days   Warning
  Used Capacity	>= 60 % In next 180 Days  Informational
  
  Example message in email received:
  Storage system SYSTEM_NAME is filling up fast. If the current
  filling rate persists, system utilization is likely to cross its
  capacity limit (configured at Storage System Used Capacity
  Percent >= xx% In Next 180 days wtihin Storage Insights)
  

Local fix

• None. Modify alert definitions within a custom alert policy if
  desired.
