Unisphere for VMAX 8.3

 

Issue:

 

 

Unisphere for VMAX can show a zero value for IOPS for an active host initiator against a particular FA port.   
    For example:   
    1. A host with two Initiators connected to 4 FA ports will show zero IOPS against one port in the INITIATOR_BY_PORT metric.   
    2. The Storage Group IOPS value is 25% higher than the sum of the 4 Initiator / FA port IOPS metrics.
                                                           

 

 

Cause:

 

 

An issue consolidating the initiator stats has been identified in Unisphere 8.3                                                           

 

 

Resolution:

 

 

Resolved in Unisphere 8.4   
    If the sum of the initiator port IOPS values are less than the Storage Group IOPS, and one of those values is zero, the zero value is being reported incorrectly.
