Savvio, Cheetah, and Constellation Enterprise Server & Storage (SCSI/FC/SAS/SATA) drives

[jakever1]

Drive model: st3450856ss (cheeta 15k.6 450GB)

Once an hour I get a handful of warning message in my Event Viewer.  They are all the same except the change denoting a different physical disk (7-14).  There is a mix of SATA and SAS drives in a Dell MD1000.  The SATA drives have not produced the error.  One SAS drive to supposedly fail last week after being online for only 1 week.  All green lights on the MD1000 and OMSA shows all is normal, but I keep getting the event log warnings.  Can anyone explain what the error or CDB is that is causing this?  Should I worry about it?  Is this causing the drives to fail?

Specs:

Dell PE 2900

Dell PERC 6/e w/512mb

Dell MD1000 with 7 Seagate 1TB SATA drives and 8 Seagate 450gb SAS drives.

I received this response from a Dell rep on their forums.  I'm posting it here because I am still not sure if it's a problem with Dell's software or Seagate's drives.

"All commands and sense data information is located in SCSI specifications.  From your log file, it appears that the problematic command is operation code 12 (CDB), which is an Inquiry command.  Because of this, the target will respond with sense data of 05 24 00, which means illegal request (5) and and asc/ascq of 24 00 which means invalid field in the CDB format.  This means that one of the fields in the defined CDB 12 01 dc 01 1d 00.  I would suspect that it is either the EVPD bit 01 (12 01), paged code DC or the second 01 (reserved) field this is the cause.

You need to determine the source of the command.  One way to do this is to turn off some unnecessary services that may generate such commands.  As a start, turn off system management software and see if the messages stop."

After uninstalling Dell's OpenManage software the errors stopped.  So are the drives doing something they shouldn't be? Or is Dell's software?
