Situation Description
Suggested Actions
CHANGE (Maximum Staging Queue Depth) is greater than or equal to 1

 

Maximum Staging Queue Depth is the maximum number of work elements on the outbound work queue since the statistics were last reset.

A nonzero value indicates that the interface is not accepting outbound data as fast as the device driver is presenting it. The maximum number is calculated each time the device driver write initiator has built as many writes as possible (due either to no remaining storage block address lists (SBALs) or no more data to be written) and is about to exit.

It is possible the device or media is simply saturated, in which case adding another link may spread the workload sufficiently to relieve the situation.

This is a warning situation.
