Issue/Introduction

The messages have to do with linux NCQ, which is a technology that improves the performance of SATA drives. The messages can be ignored as hard drives deployed in crossbeam systems don't utilize this technology.Log messages similar to the following appear in the log file:

-----

------

Cause

The messages are benign and have to do with linux NCQ, Native Command Queuing, which is a technology that improves the performance of SATA drives.

Resolution

The disks that are deployed in Crossbeam systems don't utilize this technology, so these messages can be ignored.

These messages will not be seen in XOS version 9.6 and later XOS releases..

Workaround
