RAID 10

HP Proliant 380. I've gotten tasked with trying to correct some issues with this server. It is set up with RAID 1+0. On the right side I see two disks with concurrent activity lights flashing. On the left I have on HD with an orange disk symbol with an X through it. The other disk is dark. I've reseated them but no change. I replaced them with similar disks but they are not rebuilding. On the controller I see nothing other than create or delete for the array.

Any ideas what's going on?

Can you assign the drives as hot spare?

DL380 Gen ? 4, 5, 6, 7 8?
Orange means it is failing, red means it is gone.  Needs to be replaced with an identical disk if it is Raid 1 or 5.
When the system boots and it gets to the array controller you can access the drives.  That should tell you how many disks you have in the array.
It is normal to have 2 say 146GB in Raid 1 for the OS and then 3 (or more) bigger drives for Raid 5 or higher.

give us a little more info please.

Are you able to get in to the Array Configuration Utility on the server?  What is the OS?  What Generation HP DL380?
If you can get into the Array Diagnostic Utility (on SmartStart CD if the OS will not boot) generate a report and upload it using "attach file" here. **Do not paste the text into the thread it is huge**

Server 2003, not sure what that affect for the drives not being seen.

Not sure I mentioned anything about RAID 5.

In the controller I'm showing two drives and no spares. On reboot I get drive light activity on the 'bad' drives - ones on the left side, they flicker and then go dark.
The reason I asked the OS is that you can install the HP GUI for the Array configuration tool and post a picture of what you're seeing.  It will show the bad drives and any arrays which are degraded or failed.  Can you do that and post the picture?

I'm pretty much stuck with the info that I can get from what is there now; can't install anything else, third party apps, etc.
Alright, it's an HP management tool, but I understand and it may already be installed.  

How about a picture of the front of the server indicating the issues? Or a picture of the screen in the array configuration from the POST?

If not then here is my best guess:

The two drives on the left aren't in an array at all.  Which is why you can see the "create Array" option.  The green lights will only light up if the disk is a member of an array (and during post but only for a minute).  Once they are a member of an array they are solid green when there is nothing being written and then they blink to indicate data transfer.  If they blink in a pattern (meaning on/off/on/off/on/off about one half second apart) they're rebuilding.  Since you've already replaced both of them and the one was bad, either the array is destroyed or as I said they weren't in an array to begin with.

So either the drives on the right are in a RAID 1, or they're in a RAID 0 as part of the RAID 10 and if you lose one of those drives all of your data is gone.  Without a description of how they're configured in the Array configuration, then it is hard to help you.

Ok, good point but why was one of the disks on the left showing as 'down' with the red X? And why do they blink occasionally - very random and a long time between blinks, Very little activity on reboot and they don't blink together.

If their not part of the array would I see activity lights?
Yes, that will be the controller doing routine status checks with the drives.
> "On reboot I get drive light activity on the 'bad' drives - ones on the left side, they flicker and then go dark."

If you take them out you'll still see those disk lights flash on POST, they're on the backplane and the light goes through a clear plastic light pipe to get to the front of the disk caddy. They're not connected to the drives so not much use in this situation.

Can you not reboot to the SmartStart CD / ADU / ACU and generate a report? CD is downloadable from HP's web unless they've hidden it again.

If their not part of the array why the 'X' I wouldn't imagine the array would care about these disks.

Maybe they have metadata on them that does not match the metadata on the other disks. That would make the controller put the red X LED on but it's only firmware driven so other situations can cause that too.

It's too much guesswork without you providing a report or screenshots from the management software.
Bit surprised that you have awarded points in what seems to have been a haphazard way.

I am not dissing amac81 in any way, but i fail to see why his post is any better than of the others that offered help and advice, help that was always difficult to provide, considering the paucity of information supplied, especially as you didnt provide the ACU output that Andy et al requested.
I'm at as much of a loss as you are. I was asking for more info in that post. I am quite surprised.
