Hello Roman Khan,
There are 2 ways to manage your MD1200 you can use either OMSA or the PERC Bios. Now to use OMSA you need to have Administrator rights on the server. Since you say you don’t have rights on the server then you will need to access your MD1200 via PERC bios. To access the PERC bios you will need to reboot the server and when the server is posting you can press Ctrl=R on the PERC H800 and you will enter the PERC bios. Once in the Bios you can see how your Array is configured as well as check on disk health. Here is also a link to the user guide for OMSA. http://topics-cdn.dell.com/pdf/dell-opnmang-srvr-admin-v8.0.1_User's%20Guide_en-us.pdf
