New hard drive won't go online on our Dell RAID server.

You know i find this all very suspicious. For one thing a ups is designed to take the hit so it will get fried and your computer will be fine. Suspicious to me but not an answer to your question so i will try this. The new raid card was installed (might be off on this part, haven't kept up with this) were the hard drives and the raid assembly matched back up. IE raid 1, 2, 3 etc. Do believe they are up to raid 7 now. So if hard drives were not put back in the original position and and raid card setup for the original raid array you might have this problem. Hope this helps, but it's been a long time since i worked with raid arrays.

Do a ghost on the first hard drive install ghost on new hard drive and replace, I can provide more details on procedure just ask

If you are using an image made from the IBM and it has a different processor and the board specs are different that can cause the drive not to boot it will act like it is then go into a perpetual boot. I would try to re image it again to insure that is ok on the drive also check the board If one is and AMD and the other an Intel then that would be part of the problem.

Depending on the RAID setup you have for your server. Best thing to do is search for "Dell Open Manage" software for your server and install it https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=R108443&osCode=WNET&productCode=poweredge-4400. Once installed it will give you all the information about your hardware. you should b able to rebuild RAID with same size drive if previous drive is bad, RAID will build automatically and take a long time to complete,

You will not be able to increase the hdd size of a raid array, it's size is set. If you need more storage, you can add additional drives ( either in raid or standalone ) and use the new drive(s) for storage, but the original array will remain unchanged. The other option is to back up all of your data, install new drives and create a new array.

Is the HD SAS/SCSI/SATA on a raid controller?

If so you need to enter the RAID config (not the bios, but there will be a RAID config option during the boot process CTRL+M I believe.. but it will say on screen.) Then you need to set up the raid config, then initialise, then the drive will be detected for loading the OS.

Either that or the drive(s) shafted.

What sort of disks are you using?

The raid may be fine you need to reinstall the OS.
The best way is to drop the raid array astablish a new raid array then install you new OS on a new raid array.Very nice server you have.

Its called the JBOD RAID option - just a bunch of discs.

I don't know of any system that makes a RAID array an operational imperative, I would say the answer to your question is yes.

RTFM.

Check the PowerEdge Raid Controller for parity problems. Sounds like the status on the physical volumes participating in a RAID array has been degraded.

Loud beeping from a drive is usually an indication that an invalid drive array member has resulted in a degraded logical volume.

If you were counting correctly, you had at least three drives - most likely participating in a RAID-5 setup. The array might have been rebuilt with one bad drive. But it sounds like you've got two corrupt physical volumes in the array. And that's not good.

Hope you've got a backup!

HI thanks for reply. i must say im new to this raid stuff. i was given the server by my coworker because he could not get the other drive to show in windows. he got fustrated and gave it to me. so i tey at home. ok here is what i have.

Dell poweredge 1600sc. it has two gig ram. I open the case andther it has one primary hdd and four other hdd connected on one ribbon to the board. it had windows server 2003 all ready on it. I was in the set up (ctrl +m) and i saw the drives say ready. i hit the space bar to set array. after i did that it say i had to initlize it before i reboot. now the drives say online. i boot into windows and the drives are still do not show. am i looking in the right place. i know. im stupid. go ahead and laugh.
plus is there a good place to lean this raid stuff. thanks. nezza
