HP DL180 G6 amber light but drive is OK

hphp-prolianthp-smart-array

We have an HP DL180 G6 with 25 SFF SATA drives, running 64-bit Debian Linux. A drive recently failed, so we replaced the failed drive with a new, identical part from HP. The disk controller rebuilt the logical volume and the hpacucli command now shows that the logical drive and physical drive are both OK. However, the drive still has a a solid amber light on the front bezel. Another sys admin here told me this happened when he replaced a different drive, and rebooting the server fixed it. I'd really like to avoid rebooting this server because it's about to go into production, and I don't want to go down the path of rebooting every time a drive fails. Is there something else which can be done to change the front LED back to green?

EDIT: Adding hpcaucli output as requsted by @ewwhite

So here's what I'd do.

The HP ProLiant DL180 G6 model you have is a 25-bay unit. There's a SAS expander embedded on the drive backplane and two SAS SFF-8087 cables routed to an HP Smart Array P410 PCIe controller.

Part of that is why you see the odd port:bay presentation.

I'd upgrade the backplane firmware and get your P410 controller to the last revision of 6.40. You should be able to accomplish both with the HP Service Pack for ProLiant DVD.
