Error description
-
Storage Insights reports incorrect metrics for managed capacity. Currently, ?raw capacity? is derived from ?logical capacity? metrics, instead of ?physical capacity? metrics as it should be. For RAID Arrays, physical capacity should be renamed to ?capacity? and the current ?capacity? column would be more correctly labeled as ?written capacity limit?. This is causing confusion in reported capacity metrics between Storage Insights and the FS9100/SVC native capacity metrics that are reported by the devices themselves. RECREATE STEPS: Observe discrepancies between FS9100 device metrics and those reported in Storage Insights. Problem as described by customer: Storage Insights Managed Capacity is Incorrect Initial customer impact (low/med/high): med
