Mickey, i think it shouldn't automatically mark this "new" hard drive as spare drive. So i think, that's usual behavior of array.

Mickey, unfortunately i have absolutely no experience with SAP :). But as i can see here: http://help.sap.com/saphelp_nw70/helpdata/en/04/285ea6a87f11d194a400a0c930df15/content.htm it works with MSCS without any problem. As i can see, SAP uses generic cluster agent, so you can use this documentation: http://www.microsoft.com/downloads/details.aspx?FamilyID=518d870c-fa3e-4f6a-97f5-acaf31de6dce&DisplayLang=en see file or print server cluster - i'm sure, it will be quite similar with SAP.
Good luck!
