The unexpected sense here appears to be associated with the backplane (Encl PD 20). If that is only happening at startup then it is probably just fine (specifically 06/29/00 (device reset) and 05/24/00 (invalid command) sense key/code/qualifiers). It is not uncommon to see those either of those key/code/qualifiers intermittently appear during normal operation, and not only associated with the backplane but also with one or more individual disks. If it is a constant thing (i.e .several times per second for extended periods) but the storage subsystem remains otherwise operational then you may just need to reseat the cables. You can look up specific sense key/code/qualifiers at www.t10.org/.../1spc-lst.htm or review an easy-to-read summary of common ones at en.wikipedia.org/.../Key_Code_Qualifier. Also note these are appearing in your log due to OMSA (Server Administrator) which is repeating them in syslog for convenience when they are reported by the storage controller. If you have more concerns we can pull a controller log with "omconfig storage controller action=exportlog controller=0" and take a look to make sure everything is healthy. Last but not least, it's a good idea to keep your firmware updated. If you aren't having any problems then quarterly or even yearly isn't bad, but if you start having problems and there is not an evident hardware fault we will likely recommend a firmware update during troubleshooting and diagnosis. Let us know if you have any more questions or run into anything else you want to know about. I hope you're otherwise enjoying the new server!
On our brand new Dell R420 running Ubuntu 12.04 LTS with PERC H310 we get this at startup: ---- snip ---- ---- snip ---- What dos the Unexpected sense meen, is there anything to worry about ?
