Xserve RAID expansion

Hello all, I just need to clarify something here. My Xserve RAID is hooked up to my Xserve G5 and is used to store users home directories.
I have recently added two more drives to the RAID to knock it from 700Gb to 1.4TB. I used to RAID Admin tool to expand the RAID which completed ok. It recognises the increased capacity, but of course OSX Server 10.4.11 does not, so I have to format it.
If I copy the entire contents of the RAID to another area, take the area off sharing for home directories, format the RAID with Diskutil, then copy everything back, then put it back on sharing, will it all just work again as it did before (as in no problems accessing home directories accross network).
I have to do this next week, and any help is much appreciated. Thanks

It should see the extra space. I have increased size even on Panther and it saw the additional space.

Expanding xServe RAID Array - updated info sought.

I don't want to have to reformat the RAID and I don't want to lose data because...
1) The organization will suffer extended downtime.
2) I don't have ready access to 3TB of empty storage to back up the entire contents of the RAID.
These and Apple's documentation are a few of the many different sources of info on this topic I've sought.
With apologies in advance to William Lloyd, who has answered many of these questions.

My (familiar) situation.
I inherited administration responsibilities for an xServe RAID using the latest firmware (1.5.1).
The xServe is an intel xeon dual 2 GHz, running Mac OS X Server 10.6.8
The RAID had six (sigh) drives in the left controller. None in the right.
When I became admin, one of these six was dead. So I went on eBay and got three refurb ADM's.
--one to replace the dead drive.
--another to expand the RAID 5 to a full seven drives. (from 2.5T to 2.73T)
--a third to put on the shelf as a spare.
Now then.
The replacement drive rebuilt beautifully. Happy 6 drive RAID.
I put in the 7th drive and expanded. It took several days.
I'm at the point of "merging" slices that gives everyone pause about losing data.
Much discussion here about whether this can result in added capacity without destroying data relates to earlier versions of Mac OS X Server and G5 not Intel xServes. So that's a point that I think I could use some clarity on. Can Intel Macs can expand the file system with this slice-merging function without data loss whereas Power PC Macs cannot?
Next, my RAID as I inherited it was one slice. That is to say, one volume. One partition. In RAID Admin under "Arrays and Drives" all the little drives display a [1]. They did when the RAID was degraded to 5 drives. They did when I added the 6th drive replacement. They do now, having used the Expansion function under "Advanced" to add the 7th drive.
So, next question. WAS IT EVER SLICED?
That seems to be a deal-breaker for merging slices without data loss.
For this, I looked in RAID Admin to my Events tab which dates all the way back to 2008.
I see exactly zero mentions of slicing anywhere. Come with me on a journey, won't you?
You'll see my expansion and verification up top.
The drive failure in October 2013.
Other exciting things. But no slicing.

Here I am, at the precipice. Would you click Merge?

Intel Xserve + Xserve RAID + SCSI

I have a requirement for an Intel Xserve system that I can connect an Xserve RAID and SCSI tape autoloader to. It seems that Apple won't let me configure a system with a SCSI card and a fibre channel card in it at the same time, and repeated phone calls to them have yielded precisely nothing (very disappointed with the lack of professionalism and knowledge displayed by the Apple sales and tech staff on this matter).
Can I have such a configuration? It seems that I can only fit a fibre channel PCIe card in expansion slot 1 as it is too long to fit in slot 2 which is limited to 6" long cards. I've seen that Atto do PCIe SCSI cards but there is no mention on their site about whether they will fit/work in slot 2 of an Xserve and emails to them have gone unanswered.
If anyone has any info on this, or could point me in the direction of the info, I would be very grateful. Or if what I want isn't possible, ideas on how to back up a 7TB array without direct attached tape storage would also be appreciated.

Actually, having just looked at the store, Apple
don't seem to offer any PCIe SCSI cards, just a PCI-X
one with a PCI-X riser. Would this configuration stop
me using a PCIe card in slot 2?
Avoid the Apple BTO SCSI card like the plague. It's junk.
It's really a rebranded LSI Logic 22320. Ours never worked
right in our Xserve G5; we replaced it with an ATTO UL4D and
all of our problems went away. The right card for the intel
Xserve is the ATTO UL5D or UL5D low profile (both are PCIe).
Link is here:

The Apple-rebranded LSI Logic 22320 sits on a shelf gathering
dust.

Dropped frames only on xserve raid

dropped frames only on xserve raid
i'm not able to capture on xserve raid without dropped frames. tihis was a working sytem bud one morning it dosn't work. i capture on mac pro internal drives or external fw drives without problems.
the xserve raid is new formated in raid level5 [mac os extended journaled and striped in raid 0 extended] and the risult of kona system test are 178mb/sec write and 167mb/sec read.
must bee enought for 8bit uncompressed pal, no? also if i divide the stripe set the system dosn't work on both controler. i tried also to change the fibrechannel cables!
i checked also the fibrechannel card with expansion slot utility and the message is that runns at maximum speed.
there are no error message on raid admin, the xserve raid appears ok.
i'm shure that the fcp settings are ok, i know the list that regard dropped frames from apple.
i'm desperate, can you help?
thanks jochen
system:
mac pro 2x3ghz-5gb ram(from apple and the hardware test on the system dvd is ok)
osx 10.4.10
fibre channel card: lsilogic firmware 1.2.18.0 in slot 4
xserve raid 15x250gb firmware 1.5.1/ 151c
aja io (driver 3.0)
raid admin 1.5.1 (diver 1.0)
fcp 5.1.4

I'm guessing conditioning is the same as optimization, but I can't find anything about it in the help documentation. I ran another capture test today with no problems.
An interesting side event is that when I started experiencing dropped frames I ran the Kona System Test utility to verify write and read speeds. It wouldn't run (no write or read) on my RAID. I tried it on my Firewire drives with no problems. I discovered that in the Kona System Test preferences there is a choice of I/O API for Macintosh or Unix. When switching to the Unix I/O API the test ran fine with expected read and write speeds reported. I've used the Kona utility in the past without having to change that setting. I sent an inquiry to AJA.

Need second Xserve RAID, need advice

We have 1 Xserve RAID with 14 x 400Gb Drives, It is RAID 50
we are rapidly using up the space and need to know the easiest method for adding capacity.
We want the two RAIDs to show up as a single volume, so when we buy the second Xserve RAID will it need to be the same capacity as the first i.e 14 x 400Gb drives?
Also what is the procedure for adding this second RAID, will it involve backing up the data, wiping and rebuilding both RAIDs as RAID 50. or is there a way to do this without wiping data?
Anyone who has been in this position I would be grateful of their advice

First off, ideally the arrays should be the same size. Mixing drive sizes in an array is never a good idea. Usually the RAID controller will base the array on the smallest volume in the set and just use whatever it needs from the others, leaving the rest of the space unused (and inaccessible). e.g. if you try to RAID a 500GB volume and a 750GB volume, the 750GB volume will be treated like a 500GB volume and you lose the extra 250GB.
By far the safest option is to do as you describe - backup the data, rebuild the array and restore the data.
There is one other option, though, that might work, but I'd still backup the data before trying it.
diskutil has an addToRAID option which allows the addition of an extra drive to a RAID set. I've only ever used it on RAID 1 mirrors, never on a RAID 0 stripe, so I don't know if it'll work, but it might be worth trying. You don't have anything to lose.
Note that this kind of expansion isn't really viable long-term. If you expect to do this frequently you might consider alternative options like XSAN which can add any sized volume to a virtual pool of storage, growing organically.

Expanding a XServe RAID and Striping

Greetings!
I have an XServe RAID with four 250 GB ADMs inside the 1-4 slots of the Upper or left controller. This one array totals 701.27 GB at RAID 5 showing up on my Desktop as one RAID.
I recently acquired two ADMs, a 750 GB and 500 GB, and I'd like to install them in my vacant second controller on the right, slots 8-9. I'm pretty sure I can create another array with these two drives setting them at RAID 5. Then what I'd like to do is stripe the two arrays, using Disk Utility, and create a software RAID that will show up on my desktop as one RAID. (I currently use this RAID as my Final Cut Pro media drive.)
My questions are: Am I on the right path?
If I stripe them together, I will lose my data on my existing array, correct? (I have the data backed up on another external drive so when I'm done I can copy it back)
I feel is best to have one RAID rather than several. Or should I consider having two RAIDs but being cognizant that I will have to stay on top of of my Final Cut Capture Scratch media folders as I edit? (ie, Two RAIDS = two separate Capture Scratch folders. So I'd have to choose what Final Cut media will be on what RAID, etc. rather than one folder where all the media can go)
My goal down the road is to completely populate the left/top controller with 250 GB ADMs. If I do, I would assume I can expand the side with the 250's by merely using the Expansion function? Would this "upset" the prospect of having a single RAID of two striped arrays?
Thanks in advance!

This doesn't sound like a good idea. You're mixing stuff in a variety of configurations that don't match, and if you want to stripe the two sides, they should match for optimal performance.
As in: they should all be 250 GB ADMs, right?
With the 750 GB and 500 GB drives, your options are RAID 0 (with NO protection) giving ~ 1 TB of storage, or RAID 1 (mirror) giving ~450 GB of storage. The latter is probably preferable.
So I could install them into the right side controller and make an array of the two using RAID 1 (mirror) and end up with 450 GB of storage. I'll get the protection but losing the extra storage because it would defer to the smaller size 500 GB ADM. And I can't add them to the other side where the 250 GB ADMs are because you're not supposed to mix different size ADMs on the same controller. (This is the stuff that is not in Apple's fine print when they sell it to you. You find it out either through Discussion threads or Technical Articles.)
If you were to attempt to stripe this with the other side, you'd have either 1.4 TB or 900 GB of storage, respectively. In the former case, if one of the drives on the right side failed, you would lose 100% of your data on the entire volume.
My option(s) would be: install the two non-compatible sized drives into the right side controller, combine them as a RAID 1 array and then have two separate RAIDs on my desktop, with the second RAID being physically larger than the other but actually smaller because of the incompatible 750 and 500 GB sizes. Then, when editing with Final Cut, I'd have to choose which RAID that I wanted to store my media on.
So if I were you, I'd give up trying to make it look like one volume.
Agreed. But are there any other options I can explore? I purchased the 750 and 500 GB drives naively thinking I could expand the storage of my Xserve RAID by buying larger drives. Now I'm finding out I should have purchased only 250 GB ADMs-- but they weren't available from Apple when I was able to purchase additional drives and no one told me otherwise. Until now.
Thanks for your learned reply. I guess I should have consulted with you/Xserve RAID Discussions before buying anything.

Xserve Raid Not Showing all Drives Empty - No Green Lights on Xserve Raid Drives

I have an Xserve Raid. I recently set it up with my Xserve server with fiber cables and now when the Xserve Raid system boots and starts all the drives show as empty in the Raid monitor. Not sure if I have something configured wrong and I think I shut it down incorrectly before I got it hooked up right. When I first got it I was able to see the lights on all the drives but now it boots but no drives show up at all. I have fiber cables to the host Xserve machine and the Xserve Raid plugged into the network with only 1x ethernet cables (not 2 if that makes a difference). When I try to manage the Xserve Raid all drives show as empty even though all the 500GB drives are plugged in. Not seeing any green lights when the Xserve raid boots indicates something is up. I reset the controller cards to stock with the paper clip to factory settings. Does anyone have any ideas on what to try. Anyone have this issue? I haven't found any discussions except one that had a single side of drives go down because of a bad controller card. My Xserve Raid shows no drives at all. Any help is appreciated.

Expansion is a 2 step process: First, you expand the array. Second, you merge the slices. The documentation is clear on step #2, but the GUI doesn't FORCE you to do it. However, it is necessary.
If you did both steps, try rebooting your host and see if it picks up the changed size. It does work... the usual issue though is growing the file system to recognize the additional size. On Linux, I can't help you.

Expanding XServe RAID set - stuck at 99%

We have an XServe RAID. One side had a RAID 5 set consisting of 6x500GB HDD's. We came to within 60Gb of filling it up and therefore initiated expansion of RAID set to 7th drive on Saturday. This was progressing 1% / 40 mins. We calculated that it would not complete before Monday when users would start hammering it, but after testing it, it seemed to be working perfectly fine while expanding. Writing/reading speed did not seem to be noticeably affected and we decided that all seemed well.
Monday started off well. Not not a single user noticed reduced speed or any other problems - This was until about 3pm when the file server hosting AFP & SMB crashed! Not good! Upon restart, the RAID set would not mount again.
RAID Admin shows the expansion at 99%.   I was hoping that the RAID set could be mounted again once it completed to 100%, but it does not seem like this will be happening anytime soon - it has been stuck on 99% for about 6 hours now and I don't know when/if it will ever finish. (Previously 1% every 40mins)
The fibre channel preference pane shows "Link Established" to the XServe RAID, similarly the RAID Utility shows "Link Up" to server. The RAID, however, does not appear in Disk Utility - even after restarts.
Does anyone out there have experience expanding a RAID Set on an XServe RAID? Does it usually stall at 99%? How long does it take to finish once it has reached 99%?
Is there anything I can do to try and get the RAID Set mounted before it finishes its expansion? It's now 8pm here (GMT+8) and users have finished for the day, but we only have about 12 hours before it needs to be up and running again!
I am out of ideas to try. Any help would be greatly appreciated.
Thanks

Expanding XServe RAID on 10.5 for 10.4.11 Server?

We have an XServe RAID on an XServe G5 running Mac OS X Server 10.4.11. We recently added three more drives to our Raidset, but I now see that Mac OS Server 10.4.11 is unable to use the additional space though I did the expansion and slice merging with the Raid Admin tool. If I boot this server off of a Mac OS X 10.5 client system will I be able to complete the expansion and they could I reboot the server as Mac OS X 10.4.11 and have the additional space available? Or must I upgrade to Mac OS X Server 10.5. I know I can always back up the data reformat the drive and copy the data back, but am attempting to avoid that if possible.

If I boot this server off of a Mac OS X 10.5 client system will I be able to complete the expansion
No.
Or must I upgrade to Mac OS X Server 10.5
Won't make any difference. The issue is not with the OS version, but the disk partition/format.
I know I can always back up the data reformat the drive and copy the data back, but am attempting to avoid that if possible.
That's your solution, I'm afraid.

Xserve RAID Admin Tool 1.5.1 not quite working

I have an Xserve RAID that's currently at firmware 1.3.2/1.26a according to Xserve RAID Admin Tool 1.5.1. However, when I try to upgrade the firmware to 1.5.1 via the RAID Admin Tool 1.5.1, it just doesn't do anything--it accepts the .xfb file and then...nothing. Quitting out of the the Admin Tool and restarting still shows the firmware at 1.3.2/1.26a. Same thing if I shut down and restart the Xserve RAID from the RAID Admin tool. Any tips? There's nothing stored on the RAID system yet (the array hasn't even been created--it's a blank system) and nothing is attached to it either (I've just plugged in the ethernet links to format it first before I start attaching an Xserve G5 to it). Also, even though the lower controller is showing green and I have an ethernet cable plugged into it, I can't get any info out of it nor can I configure it with an IP address. Only the top controller seems to allow some configuration such as IP address.

Okay, I've solved the problem.
Basically, the issue was that the lower controller wasn't seated right despite it showing a green light in RAID Admin. When I went to visually inspect it, I noticed that despite what RAID Admin 1.5.1 claimed, its light wasn't even on, let alone green. And since the lower controller handles slots 8-14 of an Xserve RAID and my slots 8-14 are totally unpopulated (empty) at the moment, it was never noticed. Now that I've reseated the lower controller, everything is visually showing green across the board and the firmware upgrade is proceeding as expected and it has upgraded the firmware from 1.3.2/1.26a to 1.5.1/1.5.1c complete with autorestart of both upper and lower controller modules.
Basic lesson learned: RAID Admin lies. If possible, visually inspect the box itself!
Thanks to all who responded.

Switching to Xserver/Xserve RAID

Hi boys and girls...
I was looking for a little assistance in switching over to Xserve. Let me give you some background info first.
Were a small studio in London, with only 11 people in-house and the majority working externally whether free-lance, from home or from another country etc. Were mostly Mac based, though 4 machines are those little beige pc things all running XP 2002. At the minute its 1 G5 and a collection of G4 tower's and G4 power book's, G4 cube's and so on. Were all connected to a G4 server running Mac OS X Server 10.2.8 with a very small dual 120GB HD raid thing running Retrospect.
Our problem is, this system was set up some time ago and were starting to outgrow it.
What were looking for is a way to backup all of our current work and archive all of our old work. Most users like to work directly off the server as theres so much file sharing between the macs and pc's, directly updating files so there isnt any duplication etc.
First question, is it possible (and a good/bad idea ?) to have 10-15 users working directly from a Mac server, that stores the archived work for users to reference and also current work which is backed up to tape and duplicated (as we currently have) to another HD?
Secondly, Is the ideal way to be running things? Is there a more efficent way?
Finally, what kind of spec should we be looking at? There's such a huge difference between servers, while were willing to invest, we dont want to go crazy (maybe a little) on costs.
I look forward to your responses and thank you in advance
Marcus

There are certainly some drawbacks with your current setup that mean you should make some changes.
In general, there's nothing wrong with working with files directly off the server, however, 10.2.8 has some issues with multiple users accessing the same files at the same time, so you should look to move to 10.4 ASAP to address that issue, regardless of any other changes you make.
I am assuming that the remote users don't work this way - uploading/download files as appropriate - it would be painful to work off the server remotely.
The only real disadvantage with working with files directly off the server is that if a file is changed erroneously and saved, there's no easy backup.
If the file was copied to the local drive and saved, it's easy to roll back to the previous version by re-copying it from the server, but if that change is saved directly to the server the only rollback involves pulling out Retrospect.
The other change that would make a difference is installing a gigabit switch and connecting the server to it. Even if all the host systems don't have gigabit ethernet, the extra bandwidth to the server will definitely help.
As for a new server, 10-15 file sharing users are not likely to stress the server, do you don't need a top-of-the-line configuration.
You should first decide how much disk space you need. With 500GB drives, the XServe can handle up to 1.5TB on its own, without any additional XServe RAID. However, you might want to consider RAID (using RAID you're limited to 1TB of RAID 5 storage, or 500GB of mirrored storage in the box).
In addition to your current data usage, consider using an online disk backup where multiple copies of the data is stored on the server itself before (or in addition to) backing up to tape.
While tapes offer several long-term archive advantages, they really don't work so well for quick restores of a file or two. Having a snapshot of the last couple of days data online makes it trivial to step back a day or so without having to resort to tapes. This may mean, though, that your 100GB of data requires 200 or 300GB of disk space.
If you do decide than an XServe RAID is the right solution, consider getting it right-sized from the get-go rather than buying it small (e.g. 4 drives) and adding later. While it can be done, adding drives to an existing array is a PITA.
If you do opt for an XServe RAID, and you don't currently have any rack-mounted equipment, consider using a PowerMac G5 as your server rather than an XServe. While similar in terms of performance, the PowerMac can work out cheaper depending on configuration.

Can I move Array from one Xserve RAID to another and keep the data

I'd like to move a set of disk with an existing Array from one Xserve RAID to another. Can I simply shutdown both Xserve RAIDs and move the disk over, assuming I put the disk back in the same order?

Yes, you should be able to do this.
BE SURE YOU HAVE A BACKUP FIRST.

Clarification on how to use Xserve Raid and Fibre Channel without xsan.

First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
I never thought of that. I will try that while I await for your answer, thanks again.
Todd Buhmiller
I have the following setup:
Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
Qlogic Sanbox 5600
Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
Here is the problem.
The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
Anybody have any suggestions?
Thanks

Re: Xserve Raid Mounts, Corrupt Directory tired of rebuilding directory
Posted: Jun 27, 2010 1:25 PM in response to: Todd Buhmiller
Are multiple computers accessing the same data on the RAID at the same time?
If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.
HTH,

Intel Xserve, G5 XServes, XRAID, Promise

+The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
+Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
Hope that's clear,

Can't copy files to Xserve Raid

Hello,
I'm having serious issues copying files to my work's Xserve Raid. When I try to copy files to it, it stalls for several minutes trying to copy, but making no progress, before giving an error saying:
"The Finder cannot complete the operation because some data in "filename" could not be read or written. (error code -36)"
When I click ok, I get disconnected from the Raid.
Any thoughts as to what could be happening?

What do your logs say? I'd check your afp (or whatever sharing mechanism you're using) and I'd keep an eye out for any fibre channel or LUN messages that might indicate connection/communication problems with RAID itself. (These might show up as LIP messages.)
Sounds to me like an underlying communications issue rather than a file sharing issue but without more information it's hard to say.
Good luck,
=Tod

Xserve RAID lost RAID 5 array on right/bottom controller

I cleanly shut down an Xserve G5 with an Xserve RAID attached and then powered off the Xserve RAID this morning. I replaced a failing memory module in the Xserve and moved the rack 6". I then powered on the Xserve RAID, waited for a couple minutes until it was fully booted, and then booted the Xserve. When it came up, my RAID 50 volume failed to mount. Upon further investigation, it appears that the RAID 5 array on the right hand disks is "gone". In RAID Admin (Disks and Drives tab), the left side array is visible, but all disks on the right side list status as "OK" and Type: as "Spare".
Configuration: Xserve RAID with 14 250 GB disks. Each side was configured with 6 disks in a RAID 5 array and one spare. These were striped using Software RAID on the Xserve into RAID 50 and mounted as a single volume. The RAID firmware is currently 1.5 and the Xserve is running OS X Server 10.4.3.
To summarize today's activities: under Apple's guidance (as this entire system is covered under a Premium Support contract), I swapped the (bottom) controller for the right side, updated firmware (from v1.3/1.20a to 1.5/1.50), multiple resets of both controllers, repeated forced firmware updates, etc.
Also, I swapped the left set of disks for the right set, and the array from the left set now shows up on the right side, and the missing array from the right is still missing with the disks on the left side. I replaced the disks to their original positions with the same results.
RAID Admin's Utility "Recognize Array" will not perform any operations on the rigth side disks and Apple tells me that there's nothing further that I can do with it.
None of this has solved the problem or substantially changed the issue, and the disks on the right side are still missing their associated array. Apple is unable/unwilling to offer any further help except to refer me to 3rd party data recovery services.
Does anyone have any suggestion at all that might possibly recover the missing array? Is anyone aware of any tools that I might use to recreate the RAID 5 array on the right controller? I was hoping that there might exist some low-level tools with which the disks could be recreated into an array by hand? Are there any commercial products that would work on this? Any other ideas?
Many thanks for any suggestions.

Xserve RAID (14 250GB disks) on Xserve G5 Mac OS X (10.4.3)

Not sure why you swapped the controllers back and forth
William, I don't think I was clear on this. I swapped the controller with a new controller that I had in a spare parts kit. This was at Apple's request.
really, RAID is not a backup...
I'm well aware, but despite my incessant warnings, users will become lulled in to a false sense of security when something "just works" for a very long time. This array wasn't intended to store valuable data that couldn't be lost, but...
It may be possible for Apple to re-create the RAID set, did you ask AppleCare about the possibility?
Apple has told me more than once that there's nothing else that they can do for me...and yet I keep calling back.
I was surprised that this array was lost when there were absolutely no prior signs of a problem and the system was merely shutdown and restarted cleanly. I'm more surprised and quite disappointed to learn that Apple will do nothing else for me (under a Premium Support contract) to attempt to repair a damaged array. When I asked questions about where the RAID information is stored, I received the answers: "I can't tell you that" and "Apple doesn't release that information". I did not get the feeling that they were working with me, but rather holding my hand while they walked me through published documentation.
I expected that there would be utilities (analagous to filesystem repair utilities) such as RAID Admin's "Recognize Array" that could help repair and recover damaged array data. I think that the lesson that I've leanred today is that I was naive to have expected such a thing without actually having investigated it ahead of time.
Anyway, thanks for your input, William.
