I have discussed our issue with Dell support last month, Dell support escalated the issue through there internal support to product support SME and verified that there is a bug in openmanage version 7.3. Open manage shouldnt be able to show any drives attached to the SAS HBA but for some reason it was trying too. This issue should be fixed in the next release such is due March 2014. As long as the MDSM is reporting the disks as good then all should be ok.
We have just setup two new servers with san in the following configuration: Dell R620 x2 with 2012 hyper configured in a cluster connected to MD3220 via SAS with one SAS cable on each of the 2 onboard controllers.   Dell Openmanage is reporting failed two drives on 6Gbps SAS HBA controller 0 and 1. Upon checking the MD3220 no drives have failed. Below is an extract from the logs ID 0:7 Status Critical Name Physical Device 0:7 State Failed Execute  Bus Protocol SAS Media HDD Revision 0784 Capacity 0.00GB Used RAID Disk Space 0.00GB Vendor ID DELL Product ID MD32xx Serial No.  Negotiated Speed 6.00 Gbps SAS Address 590B11C406C46904 Has anybody encountered errors similar to these? Cheers, Dave
