Resolution

Alert ID RESOURCE_BALANCER_TIME_TO_FULL_CLUSTER_BELOW_MAJOR_THRESHOLD
RESOURCE_BALANCER_TIME_TO_FULL_APPLIANCE_BELOW_MAJOR_THRESHOLD
Alert Text The cluster is projected to run out of space in %(ttf_days) days.
The appliance %(object_id) is projected to run out of space in %(ttf_days) days.
Error Code (0x00A00301) (0x00A00401) 
Description An appliance(s) within a PowerStore cluster or the entire cluster is running low on storage space. The customer is alerted daily until the issue is resolved to avoid running out of storage space entirely. When PowerStore runs out of storage space, it goes into "read-only" mode.
Resolution Cause
Based on predictive analytics, an appliance(s) within a PowerStore cluster or the entire cluster is projected to run out of storage space within 14 days. There are three internal thresholds the system uses to determine when to alert the user:         
  • Major alert: (1 day – 14 days):     Alerts 0x00A00401 and 0x00A00301         
  • Minor alert: (15 days – 28 days): Alerts 0x00A00402 and 0x00A00302         
  • Okay (4+ weeks)
When the system object is projected to run out of storage space in 14 days the user will get a major alert . The system object may be an appliance within a PowerStore cluster or the entire PowerStore cluster. Alerts will continue daily until the issue is resolved.

Solution
When a major alert is raised for an appliance that is predicted to run out of space, the alert details dialog window guides the user through a repair workflow.
alert details dialog window
 
The PowerStore Manager Repair Flow offers the following options:       
  • Assisted Migration. The system recommends where storage should be migrated within the cluster.         
  • Add more Drives. The user is guided to the General Support page for assistance.         
  • Consider deleting unused snapshots or volumes.
Alternatively, the migration recommendation REST APIs can be used if Assisted Migration is desired using the REST API (/api/rest/migration_recommendation). Refer to the REST API Reference Guide for PowerStore in PowerStore Info Hub for additional information.
 
When a major alert is raised for a cluster that is predicted to run out of space, one of the following actions can be performed:
  • add more drives
  • add an expansion enclosure
  • delete unused snapshots or volumes
 
 
Alert ID RESOURCE_BALANCER_TIME_TO_FULL_APPLIANCE_BELOW_MINOR_THRESHOLD
RESOURCE_BALANCER_TIME_TO_FULL_CLUSTER_BELOW_MINOR_THRESHOLD
Alert Text Appliance %(object_id) is projected to run out of space in %(ttf_days) days.
The cluster is projected to run out of space in %(ttf_days) days.
Error Code (0x00A00302) (0x00A00402)
Description An appliance(s) within a PowerStore cluster or the entire cluster is running low on storage space. The customer is alerted daily until the issue is resolved to avoid running out of storage space entirely. When PowerStore runs out of storage space, it goes into "read-only" mode.
Resolution Cause
Based on predictive analytics, an appliance(s) within a PowerStore cluster or the entire cluster is projected to run out of storage space within 28 days. There are three internal thresholds the system uses to determine when to alert the user:         
  • Major alert: (1 day – 14 days):  Alerts 0x00A00401 and 0x00A00301         
  • Minor alert: (15 days – 28 days): Alerts 0x00A00402 and 0x00A00302
  • Okay (4+ weeks)
When the system object is projected to run out of storage space in 28 days the user will get a minor alert . The system object may be an appliance within a PowerStore cluster or the entire PowerStore cluster. Alerts will continue daily until the issue is resolved.

Solution
When a minor alert is raised that a cluster or appliance is predicted to run out of space, consider one of the following:
  • migrate volumes from one appliance to another. Only applicable for appliance alerts, e,g, 0x00A00302.
  • add more drives
  • add an expansion enclosure
  • delete unused snapshots or volumes.
