Let this be a lesson to you all in Book Writing 101

Re: Snap 12000 info / help?
 

Very well expained, Phoenix32.

My hair drier is on the other side of my house so I don't have to listen to it. After awhile you just ignore it, kind of like a squeek in a car. It's also the warmest part of the house.

Re: Snap 12000 info / help?
 

Thanks (I think) for the 4000 info. My current configs:

4000 w/ 300GB RAID5 Seagate models ST3300831A-RK drives only work master / slave (even with previous 30GB drives). This one emails me errors on reboot.

4000 w/ 250GB RAID5 WD drives set to cable select. No problems seen (yet).

705N w/ 120GB RAID5 WD drives running 4 years no problems (drive config forgotten).

Back from the digression...
What is the largest RAID5 array size on the 12000? I am pretty sure that it can be configured with one four drive array and one eight drive one. Is the Snap OS 4.x RAID5 limitation 1.2TB or is that only a factor with the 4000?

Re: Snap 12000 info / help?
 

It seams too be a OS thing, the best we can tell. This is usable Storage Space. Did you test your (4000) setup by removing a drive (2)? Would be recommended. Phoenix32 ran in to problems with his. But were able to correct the problem with a cable mod. His would not report a problem, failed drive.

I elected to remove my Seagate drives and run SpinRite to check the media. I have one drive that has already used 1/2 of it spare sectors used up. Hopefully with this done it will avoid the bad areas, should help the response time. It has 5 yrs to fail.

I have 400's in my 4500, After the raid 5 set was built, I only ended up with 1.09T usable space. This was with the Guardian OS. I setup with 10% SnapShot space. It may be the reason why. The doc reported the snapshots come out of the raid5 space. The GuardianOS is huge compaired to the SnapOS.

We have little to no data on the 12000. So it would be nice to have a user post some. These were advertised as 3T units. This I suspect that was with 12 x 250gig drives, 3 x 4 drive arrays, Guardian OS?. I think the early ones were 1T. Since they post the raw drive capacity and not usable numbers. It all depends if the 1.2T limit is indeed a SnapOS limit. Does the 12000 have 6 IDE cables with the drives CS or MS? My question is how is the ide buss setup? Since yours is using the SnapOS means its one of the older units. What OS version do you have? I remember that there was a problems on loading v3 OS, v2.6 was the latest for the 12000???? I would contact snap-tech and confirm this, its a BIOS/Flashram size limit, (4m vs 8m). According to Douglas the chip can be removed on the 12000 and swapped for guardian os. At least on his engineering unit. SO if you do not have a physical copy of the flashram I'm not sure I would try a OS upgrade. I could make a backup for you if needed. Or find someone in your area and have them read the chip. This would be good info to know. It would distinguish any doubt we have about the OS. This 12000 takes a lot of $$$$ just for drives. If you have 400gig drives to test with, it would be nice to know how many the array will handle. I realize that it may take a month to build the array :D , or just 2-3 days. (We have data confirming that a snap will not accept 2 750gig in raid 0, but will in raid 1. Reported a error that a number was crazy large.)

Sorry for all the questions on the 12000, but we don't see these very often. Yours is probably only the 3rd one to come through here.

Re: Snap 12000 info / help?
 

I'll add a 4th 12000 to your list. I've got a 12000 that I'm currently attempting to put back into service. (My 4400 is maxed out as is my 2200 and my 2000 is close.) Right now it's running with a single 120GB drive and loaded with SnapOS 4.0.860. I'm attempting to upgrade it to 250GB drives (Seagate Barracuda 7200.10s with 16MB cache) but up to now I have been unable to get the 12000 to format a 250GB drive beyond the 137GB limit. I successfully formatted one of the drives to 250GB in my 2000 and then moved it into the 12000 in the second slot but the 12000 would not verify the disk or mount it.

Right now I'm contemplating trying a different type of 250GB (a WD or a Seagate 7200.9) or possibly just giving up and stepping back to 160GB drives and lose the 23GB per drive.

Any information anyone has on if it is possible to format a 250GB drive and if so what drives worked, would be appreciated. Thanks, BDK

Re: Snap 12000 info / help?
 

Drive capacity is based on the first drive. So change your setup to JBOD. Install the 250gig into drive 1, no other drives in system. Let the OS do the setup, after 10min connect and check progress.

And Interseting note I remember a while back that a 12000 would not accept v4. Only v3?. It was a early HW version.

The only user that I know with a 12000 is Snap-tech.

Re: Snap 12000 info / help?
 

No such luck. I installed a new, unformatted Seagate 160GB drive (a 7200.7 retail model) I had on the shelf in slot 1 (no other disks installed), powered up the 120000 and after many, many hours it formatted the disk to 130GB. I was just reading the posts on the 14000 thread, is it possible that removing the battery might work on a 12000 even though it runs SnapOS? Any other suggestions? Thanks, BDK

Re: Snap 12000 info / help?
 

I'm not sure that the 12000 will support drives greater than 137 gig. Snap-tech talked about 2 different bios for the 12000. One was for the snapos the other for the guardianOS. If it's a SnapOS it can have 2 raid5 of 6 drives. Reading the admin manual I do not believe it will support larger drives. I would drop Snap-tech and PM and ask him. I know he has these units.

Re: Snap 12000 info / help?
 

New Snap user here, Were is the reset botton on a SNAP 12000.
I only see the main power botton, and 3 soft keys on the display. do I use one of these keys ?
I'm assuming that I would reset it like the 2200 or 4100 that I have.

What are the console settings ?

start up display shows backplane 1.4.2, bios 3.2.667

the system light is blinking on and off about once per sec.
and the drive 1 light blinks randemly, but mainly stays off.

Re: Snap 12000 info / help?
 

Here is the reset procedure from the Snap Server 12000 Administrator's Guide:

How do I reset the Snap Server settings if I cannot connect to it?

Resetting the Snap Server to its factory default settings does not change the existing disk configuration or erase any data stored on your disks. However, clearing all of the system settings will remove the File/Folder Security and Quotas.

To reset the server settings:
1. Turn the Snap Server off (as described on page 7) and wait for all of the lights to turn off.

2. Press and hold down the center button below the LCD display. While you are still pressing the button, turn the Snap Server back on; continue to hold the button until the LCD indicates it is ready to select a maintenance mode.

3. Release the center button. To select the settings you want to clear and reset, briefly press the Reset button:

Once to clear the server's IP address.
Twice to clear the Administrator password.
Three times to clear the server's network settings.
Four times to clear all system settings.

4. Watch the LCD display to verify that the desired diagnostic mode is shown.

5. When the correct mode is displayed, use the center button below the LCD display to select that mode. The server then restarts and resets the settings you cleared to the factory defaults.

I hope this helps. If you need a copy of the document please private message me with your email address and I'll send you the pdf. BDK
