Adding to arrays in Windows 2000?

This may be a mere lack of knowledge on my end, but I'll ask anyway. Last weekend (3 days ago as of this writing), I added one physical hard drive each to two DL580 servers. Three of the four bays were occupied prior to doing this, and thus when I downed the server and launched SmartStart I was able to choose the option "Expand Raid 5 Array". Since Windows 2000 doesn't support scabbing disk space onto an existing partition, I chose to create a new partition.

When I booted the servers back up, it of course told me that it was initializing the new array config and that performance would improve when it was complete. I logged in to see if the partition was available in Disk Management. To no great surprise, I couldn't see it. I figured that in order for it to become visible, the build-out had to complete.

Well, that was Friday and this is Monday... I still don't see any available space to create a new logical drive in Disk Management. I don't even know how to be sure that the array is done doing whatever it has to do. This isn't a server I can just take down without a lot of coordination so hopefully I'm just missing a small and stupid detail on my part.

Any help, please? Thanks in advance!

Did you do anything with the logical drive (ie. new or extend)?

It may be too late now, but I would recommend looking at EM000915_CW01 (search for this on the support site).
The truth is out there, but I forgot the URL..

I'm not sure what you mean by "doing something" with the logical drives. I simply took the servers down, booted to SmartStart CD, ran the Array Config utility, chose to expand the existing Raid 5 array, then chose to make the new space into a new partition (because I would lose data if I tried expanding the existing partition due to Win2k limitations), and then I saved the config and restarted back to the Win2k server for each.

Also, thanks for the mention of the advisory, but I took a look and it definitely doesn't apply to my situation. Disk0 (the only partition other than the CD that shows up) is non-dynamic and I don't have anything in Disk Management labelled as "foreign". In fact, from that screen, it looks like I never added anything at all!

I've attached a screenshot.

I figured it out. For whatever reason, disk1 didn't show up until I ran the Compaq Array Utilities in Windows. Since the problem existed on two identical servers, I opened disk management BEFORE running CAU, and sure enough the new unformatted disk1 showed up the instant I ran that app. Didn't need to hit refresh or anything!

Just wanted to give the issue closure in case there are any lurkers here.
