Hello wardog25, For the MD1200 you need to use a PERC card as that will allow you create a raid array. The SAS 6hba that is used for your 124T is not a raid card so you will not be able to create a raid on that card. For an MD1200 we recommend that you use a PERC H800. Here is a link to the Interoperability Guide for the MD1200 & if you look on page 2 it list the supported raid controllers. ftp://ftp.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_powervault/powervault-md1200_Reference%20Guide_en-us.pdf  Here is a link to purchase a PERC H800 if you need it.    Please let us know if you have any other questions.
We have an R620 that already has Dell SAS HBA in it that is attached to a 124T tape library. Just got an MD1200 and I plugged it into the other port on the SAS HBA.  I can see the drives in Windows disk management.  I can also see them in Open Manage, but there are no options to use RAID or create virtual disks.  Should there be? In fact, OpenManage says "Connector 0 (Non-RAID)" in regards to the 6Gbps SAS HBA.   I've been looking online for drivers for that card that allow RAID and can't find any.  Am I hosed?   How do I get the RAID to work on the MD1200?
Will RAID work using MD1200 with R620 and 6Gbps SAS HBA?
