Drive 'predictive failure' (Amber flashing light) ProLIant DL380p G8 - How to replace?

We have an HP DL380p G8 with a 5 disk (5x300GB SAS) RAID that is showing one drive as 'predictive failure' with AMBER light flashing on that drive. The Array configuration utility (see screenshots) confirm this is the case. Now most drives I have to swap out are usually failed (solid AMBER light) and I can thus hot swap them whilst the server is running. Can I actually hot swap this one even though it has not failed yet or do I need to shut down to do it or mark it offline/disable in the array? A replacement drive is on its way.

When the replacement arrives just take the old one out and fit it, There's no option to offline the disk in the ACU and it should be changed hot. Safest to backup first of course and examine the ADU report to make sure the other disks are in a good state before swapping.

BTW, can't quite read the text in 2.jpg but looks like it has pretty old firmware on that disk, if you upload an ADU report we can check that the other disks are OK before you swap this one.

The moment you take out the old drive it will be marked as Failed anyway... so then you can insert the replacement in the empty slot.
