Adding a third Hard Drive

Specs: Windows Server 2003
Hey Guys,

We have a poweredge 1750 (perc 4di) we've been running with server 2003 for the past few weeks. Its currently on a RAID 1 on two drives, and we'd like to add a third larger drive to serve as the file server storage.

So we simply installed the Drive #3 as Raid 0, BIOS recognizes it okay, and windows loads for a split second before showing a 'Hardware initialization failure' error. Any ideas to get it recognized? Thanks!

You shouldn't load it as raid 0. Read up on raid configs here:

Perc 4di can handle a one disk Raid 0, question is, can server 2003 handle raid 1 and a one disk raid 0?

Thanks guys.

We got it working through Dell OpenManage Server Administrator. Instead of setting the drive to Raid 0 before windows loads, we used openmanage to configure and initialize the drive, as raid 0, and it showed up immediately.

Good luck with your data. Seriously consider mirroring your data.

Funny how dell considers raid0 with one drive. They don't even know their raid levels.
note the "RAID Level 0 requires a minimum of 2 drives to implement"

I will leave you with "GOT HOT SPARE"?

I know right? Raid 0 has always been 2+ drives, not sure when dell decided to change the rules. Luckily we have two drives running on raid 1 already, we just needed to add a third for file storage.

For those running into similar issues with a 1750, our current setup is a mirror + a standalone drive, and works great, just remember to use Dell Openmanage administrator.

Just so you are clear, you are NOT running raid 0+1

A number of folks on the web are confused about raid 0+1 and raid 10.

In your circumstance you are running neither. You are running a raid1 array and a standalone drive with no stripping and no fault tolerance.

The difference between raid 0+1 and 10 is easy to understand

0+1 is [going to the last number first] a mirror of a stripe
10 is a stripe of a mirror

The difference is raid 10 will still be operational if TWO drives fail [one in each mirror set]
This is NOT the case with raid 0+1

Both raid arrays give you a performance kick over raid5 or even over raid1.

I put database servers on Raid10. It has performed excellently and saved my data on many occasions when drives have failed.

know your raid levels before you say 1+0 is a mirror array and a standalone drive. .
