Poweredge R710 Harddisk Failed

Hi,

I am Alexander Siahaan, I have an failed disk on our RAID 5. How can I order new disk ? because I could not ask the Dell Hotline Number due to the expired Warranty.

By exchanging the failed disk, can I simply plug out the disk and plug in the new one ? Or should I disable it first and how? I could not find to disable it through OpenManage Server Admin
