RAID Card

Hey there,

Just confirming what I'm suspicious of. I have a server I build a few months ago. I put a RAID card in it that connects to the backplane via mini SAS cable. I was building the server proactively, and it wasn't a rush; so I set it aside for a couple of months after configuring the RAID and installing the OS. I just plugged it in yesterday and it wont even recognize the RAID Card on boot up. It shows in the regular bios, but when I access it there I only see one Hard Drive on it.

I'm assuming it might be a lemon RAID card? Any Thoughts?

Thanks!

Possibly a bad battery on the RAID card, otherwise a lemon if it does not have a battery.

Dead battery, loose connection or a lemon which I wouldn't use to make lemonade.

All hardware RAID cards write the container data to the disks.  If it forgot the container or you can't even see the card at post, you probably have a bad card.  

1. Pull the card
2. Flash the bios by pulling the battery on your server mobo, pulling the power and depressing the power button for 10 seconds.  (don't use the jumper)
3. Power on and SET YOUR TIME and TIMEZONE IN BIOS
4. Power off and Re-seat the card.  
5. REMOVE power from all hard drives and power on server.
6.  You should see at boot.  - if not, bad card.  If you do, corrupt BIOS or interrupt issues/legacy memory issues
7.  Power off and add hard drive power back to only container disks.
8.  Power on and Validate it wants to either import a foreign disk configuration or that it sees your original array - If foreign, corrupt card BIOS.  If disks recognized, you could still have a bad hard-drive, but I doubt it.

If you make it that far, you should be able to power off and re add all disk power and boot normally.

In server BIOS you have an option to select On-Board RAID (if present) to be used. I guess in your case this should be DISABLED.
Still in BIOS, you can select BOOT devices and your PCIe RAID controller should be among options. SELECT it.
Also check in BIOS that PCIe slot, which hosts your RAID card, is set to ENABLED.

Then upon booting, there should be a prompt for RAID controller configuration. Might be something like CTRL+C, CTRL+L or similar.
Enter RAID configuration utility and examine your RAID disk arrays. They should NOT vanish even after 2 years without electricity, because RAID disk array config is stored on disks (COD, Configuration On Disk) permanently, not on RAID card. RAID card only caches array configuration, but does not need to remember it, as it could be read from disks.
Find in RAID Confoguration Utility an option to make your disk array (Logical disk, volume...) BOOT. Usually there's just 1 or 0 under column, which marks disk array boot device. This does not actually mean that it makes it bootABLE, but rather to make your system BIOS to consider it one of boot devices.

BTW...which RAID controller you have in server?

Also, make sure you have all the power plugged back in correctly to the drive backplane
