How to get Dell poweredge 2970 to recognize hard drives?

The server did have VMware esxi on it for testing but now I need to put server 2003 on there instead.  However we did have a couple older hard drives for that server that already had server 2003 on them so I tried to swap out the sets of hard drives so that it would just read the ones that already had it.  The server would not recognize those hard drives at all.  I then tried to place the hard drives that had VMware on them back in it and now they are not recognized at all.  I have tried swapping them out and switching orders but I can not get any of them to be recognized on this machine.

eeeeek..
Your server had an existing raid array.  You should not have mixed the drives up.
Are you getting any errors in post?

What kind of drives?  What controller?
SAS drives with PERC 5 or 6?

I am not getting any errors.  I had them in the correct order and they still would not do anything.

Going along with jorlando...that's where I was going with this.  Switching drives around like that won't get you very far.  Check what post reports and also in the controller setup to see if the drives are at least being seen.

The drives are not seen at all, when going to the BIOS setup there is nothing there.

If the system doesn't see the drives, I would suggest pulling out the drives (just loosen so they are not connected) then power cycle and go into the controller setup and clear the config.  Then shut off, recede the drives and power on.  Check if the drives are now visible by the system.

Not the bios. Your drives are most likely in a raid configuration.  You need to watch the machine as it boots up and look for "power Edge Raid Controller" hit fkey to enter setup.

What exactly are you trying to do? Go ack to original config or reload from scratch?

Also, the drives may have a controller seperate from the BIOS, did you go into the disk controller BIOS also ?

I hope this helps !

I went into all the different configs and couldn't seem to figure out anything.  So what is my best bet here?

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

If you have a perc controller, it will say 'press ctrl-M to enter setup' during post when it shows "PowerEdge Raid Controller".  In there there should be an option to clear the controller config.  Unfortunately I don't have a server that I can restart right now to show the exact steps.  I assume it's a perc 5?

Probably your best bet at this point to clear the config and the drives should be seen (I've had to do this before); then you can create your new array and go from there.

download the manual from Dell for your hard drive controller - It should contain the info you need to get it configured.

I hope this helps !

It is CTRL-R for the PERC 5/6 that will be in the 2970 (or CTRL-C for a SAS 5/6).  Once in CTRL-R, hit F2 on the RAID config and clear it, then F2 to Create Virtual Disk.  Make sure you check the Advanced Options box and Initialize.

Assuming PERC5 (most 9th generation has it) start here if you need documentation:

Follow PowerEdge's instructions.  I have never seen him lead anyone astray.  You are in GOOD hands.

I went to the RAID config and tried to clear it but it seems like it isn't doing anything.  It asks if I am sure I want to do this and I say yes but when trying to go back and create a new one the option to create cannot be highlighted.

Go into the physical drives screen, do you see the disks listed there?  If so what are their status?
