Getting a few "Unexpected Sense" per day on a disk
Hello,
We have a disk that triggers this message ( in /var/log/messages )
Unexpected sense. SCSI sense data: Sense key: B Sense code: 4B Sense qualifier: 4
a few times per day. Always the same disk, always the same code.
From the wiki (https://en.wikipedia.org/wiki/Key_Code_Qualifier) , I can see that this code means:
Aborted Command - data phase error
The number of times per day that this happens seems to go up ( around 3 last week and around 6 this week) but it could be more usage of the disk.
I replaced the disk and the new disk does exactly the same.
Do I need to worry about this ?
This disk ( 600 GB) is installed in a MD1000 .
Thank you !
Gilbert

Hello Gilbert,
What is the current version of firmware on your PERC card, & your MD1000 EMM’s? Have you tried to run a consistency check on the virtual disk?
Please let us know if you have any other questions.

Hello Gilbert,
Can I get a controller log for your PERC card? I want to make sure that you don’t have a puncture on your virtual disk. Here is a link that shows how to get the log if needed. https://www.dell.com/support/article/us/en/19/sln249450/how-to-export-the-tty-perc-controller-log-via-openmanage-server-administrator-omsa-?lang=en
I will send you a private message so that you can send me the controller log. When was your most recent backup of the virtual disk?
Please let us know if you have any other questions.
