Replacing A "Predictive Failure" State Disk

[MuriloAssis]

Hello everyone,

I have a Proliant Server running a P420i controller with two disks with the configuration below:

- Port 1I - Box 2 - Bay 1: 300 GB

- Port 2I - Box 2 - Bay 5: 600 GB 

-- SAS Array A;

--- Logical Drive 1 (80 GB, RAID 1)

--- Logical Drive 2 (398,7 GB, RAIC 0)

The 600 GB disk has entered predictive failure state recently. This server is the main Domain Controller for Windows Active Directory, with other key services running (DNS, DHCP etc.) and is also the file server, meaning that I cannot afford to lose this server, at least for now (it is a ten year old server that I'm looking to replace soon, but I still have to convince my superiors).

I had a spare hard drive which I've installed on the Port 2I - Box 2 - Bay 6 (right below the one with error) and set it as Active Spare in HP Array Configuration Utility, but I don't know if this is the correct proccess (probably not), as it is only shown as Active Spare but it doesn't seems to be really active.

So, what should I really do now? Is there a way to copy all the data from the failing disk to the new one and set this new disk as fully operational and remove the failing one?

Thank you for your help.

How many HDDs are in SAS Array A ?
