HP Array Configuration Utility CLI, help with commands after replacing a faulty drive

We've had a drive failure in a RAID 5 array and I'm unsure how to get it to see the replaced drive (assuming its the drive and not the controller at fault) and to start the rebuild.

=> controller all show config detail

Hi

Try the simple command     rescan

If not helping you please check this document, from page 45 they cover the CLI.

rescan fails to show new drive in controller all show config detail and I'm struggling to find an appropriate command in that doc that maybe I need to use.

No commands are required when replacing disks on Smart Array controllers so long as they are fitted hot. It's all automatic. Yours says E: so if it's Windows the GUI version of the ACU is much easier to use although again you don't need to use it when replacing disks.

It depends on how priority is set but i am also expecting the rebuild to start automatically.

If you have the oppertunity taking down that server for a couple of minutes, maybe the raid controller needs a cold reboot.

I've done a couple of cold reboots which hasnt helped. Ive also just installed the GUI ACU but the failed drive which i've replaced is showing as failed and I can't find any way to get it to see the new drive. I have tried a hot swap too but that didnt change anything. It is a little warm and i can hear it spin up ok.

Do you have a spare slot to put it in? You won't be able to do anything with it with the array degraded/failed but at least you can verify if it sees it.

I have managed to fit a second 4 way cable to the card and i can now see the drive on one of the ports on that set of 4 cables. It appears the controller just cannot see drive 4 on the first 4 way sata slot. Can anyone direct me to adding this drive to the array in place of the missing one as i cannot seem to do anything at all because its failing as it cannot see the missing drive?

You have to replace the drive in the failed slot, there's no option to use a drive from a different slot unfortunately. If it doesn't see any disk in the slot when you put the replacement in then most likely problem is backplane, then cable, then controller. At least you can eliminate the cable easily. It's very important with HP controllers to replace hot, they can get stuck in interim recovery mode if you replace them cold.

Sadly the controller will not recognise the failed drive in any port. I moved all drives to the second port on another cable but it appears whatever killed the drive (which is making awful noises and is obviously dead) has also killed the port it was connected to so I can see no way of rebuilding the array. Sadly, I'm going to have to rebuild on another drive. Thanks for all your help though, much appreciated.

If it's the backplane they're only about $100 depending what model/generation server it is and they're not hard to replace if you have a decent torx driver as opposed to the service tool that' clipped to the server.

Thanks for that. Sadly there is no backplane, its a direct cable off two ports on the raid card, I've tried replacing the cable with the same results. I even moved all the drives to the other port where it saw the array and just booted up but still wont recognise that the 4th drive moved as it expects it in the original port which doesn't work!

Yeah, annoying that you can move working drives to different ports and it automatically updates the location map in the metadata but you can't do the same with a replacement disk and can't even assign a hot spare as a temporary fix. There's an E200 PCI card on eBay for £30, no cache but you can transfer your current module; if yours is an e200i on the motherboard you can still replace with a stand-up PCI card. A P400 would do as well although that won't take your cache module.

That's brilliant, I hadn't thought about doing that. It is a PCI E200 card that's in there at the moment so I can swap the module like you say, so I'll try and swap that and see if solves it. Just ordered the card off ebay :-) Thanks
