Yes. Unless you're using HP-Ux's LVM or some other Logical Volume Management software package, the controller can only perform mirroring on the same channel. I see no value in running Raid 10... all it does is strip the mirrored data on the 2nd set of disks. It uses the same overhead as mirroring and offers minimal benefit with the potential for more overhead in slowed bandwidth. Make it simple and just mirror the drives with Raid 1.

Need scsi/raid drivers on floppy to install winxp pro (at f6 prompt)

Hello the drivers can be downloaded here:

You need to unzip the file before you install the driver.
It should not be nessesary to install drivers before installing the windows system.
Check your bios boot settings to boot from the cdrom or dvd drive.
The cd or dvd drive must be the first boot device in order to boot from the windows disk.
Install windows with only one harddrive.
You can also add a harddrive later, when the installation is done and all drivers is installed.

Good luck

I was running 2 scsi drives in a raid 0. One drive failed, how can i retrieve the files off the the still working drive, and can i?

Hi there, Sorry to break the bad news, but when one hard drive fails in a RAID 0 configuration, all data is lost. Your only chance is to take it to a professional data recovery center, where you could be charged hundreds, or thousands of dollars for a data restore. Seagate will do these recoveries for you. RAID 0 has no redundancy, unfortunately. Sorry about that, Alex

CAn I disable RAID on a DEll powervault 770n server

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.

No SCSI Chips found on the adapter

This is a serious problem and you could easily guess wrong and blow away your data.
Good news is that Dell servers have lifetime support. Without a warranty you will have to pay for any parts you need but, if you are lucky, you won't need any. If you do get the part # from Dell and check eBay for it.
Get the Service Tag from the server and call Dell Technical Support.
You can get the phone # from their website.

Meaning of Symbols on Hd rack?

If the server is configured with split SCSI channels these indicate which bays are part of each of the two channels. The common use for this would be to use the split with two drives for a RAID 1 system drive and the remaining four for RAID 5 data or in some cases two sets of RAID 1.

Raid 0 on Intellistation 6221?

That particular work station comes with both IDE and SCSI drive interface controllers. The IDE drive should be used for your OS. The SCSI drives for your data storage. Now, the issue is to get the SCSI to work in RAID_0 as I understand.

You iwll need a RAID controller such as Adaptec AHA-3940AU WD SCSI Host Controller, which may be found on eBay (used) for a very affordable price. The driver software may be downloaded directly from Adaptec, so I suggest you do that in the iterim peroid, and store drivers on a USB thumb drive.

Hope this helps you.

Service Tag 277MW0j-DY

The best solution is to get another power supply and back the data up.

If you can't do that, and you have SCSI drives, then I would suggest marking the drives (0, 1, 2, 3, etc) and putting them in another Dell Power Edge server with the same RAID card and reading them that way. It can be dangerous to your data if you don't know what you are doing.

There are programs out there that can help you re-construct your RAID if needed. CaptainNemo and RAID Reconstructor have helped me in the past. If you have a Dell Perc 3/DI in your existing server, I may have the parameters for those programs.

Let me know.
