I have a Fujitsu host (PRIMERGY RX300 S6) running Windows Server 2008 R2 and Hyper-V (Version 6.1) with two virtual servers (one Windows Server 2008 R2 and one Windows Server 2012). Our 25 employees are continually connected to the virtual servers during the workday and read and write files to shared folders.
The storage controller on the host is RAID Ctrl SAS 6G 5/6 512MB (D2616) by LSI Corp.
Recently, I have discovered that the Raid manager displays very frequent warning messages. Nearly one every minute and sometimes up to 15 or 20 a minute.
Each warning message looks like the following:
-------
Event: Warning
Date: Mar 18, 2015, 1:04:49 PM
Source: TOSHIBA MBF2600RC (1:0)
ID: 10909
Event: Adapter FTS RAID Ctrl SAS 6G 5/6 512MB (D2616) (0): Unexpected sense:
Disk (1:0), CDB:28 00 1B 02 B5 80 00 00 80 00, Sense:(command aborted)72 0B 4B 04 00 00 00 20 80 1E 00 28 52 08 01 00 50 03 00 57 00 F3 3F 40 50 06 05 B0 00 02 72 BF 00 01 0C 00 00 00 00 00
------
Unfortunately, I have not been able to find out when this warning message started to occur.
The reason I am somewhat concerned about the warnings – apart from it just looking strange to me – is that Backup Exec has suddenly began to take 3-4 hours longer than usual to complete and now takes around 22-23 hours. Comparing job properties I can see that the job rate of Backup Exec for this particular server is down from around 800 MB/min to 550 MB/min.
My hardware provider has informed me that the message is merely informational, and that we should probably have the server replaced. It is 3,5 years old and I guess we should have it replaced within a year, but I would still like to get to the bottom of this matter.

The error decode is Bh/4Bh/0Bh = ABORTED_COMMAND/NAK_RECEIVED. I wrote my own tool to decode these and try to give a basic assessment at http://scsi.ev-en.org/
These errors indicate that you have a bad link somewhere, most often it is a bad cable but it can also be a bad port on either side (drive or slot).
