XServe G5 unable to boot from raid 5 partition (Apple PCI raid card)

I've installed Leopard Server on a raid 5 partition, on a XServe G5 with an Apple PCI raid card, but I can't boot from that partition.
This server was running on 10.3 server with the same partition since 4 years and they where no problem.
Somebody have a suggestion ?

Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)

Hi PPl,
It happened second time in a row. Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)
When the disk was found faulty, still unable to boot the OS from alternate disk, it says it still probe/look for other disk
Here are the console log when I tried to boot the OS
sc> console
Enter #. to return to ALOM.

In such condition left out with only two options.
1) Remove the faulty disk physically and boot
(or)
2) Replace the faulty disk and boot it
Any way, I can disable the faulty disk in BIOS (or) booting from cd-rom and do something to avoid it?

You can't boot from systems earlier than that shipped with the computer. For example, early 2008 Mac Pros come with 10.5.1 and can't boot 10.5
Also you can't boot with a DVD that was shipped with a different model Mac.

UCS Unable to boot from SAN

I have some blades that I'm unable to boot from SAN. The weird thing is I can see the LUN's and I can install ESXi 5.5 fine. It's up until I reboot and the blades just boot to the BIOS because they don't see any disk. When I try to change boot order, the only thing I can boot to is UEFI.

When you see your lun, and can install ESXi, it means, that
- your zoning is correct
- your lun masking / mapping is correct
If boot fails, your boot policy is the problem ! are you sure, that the target pwwn points to the controller of the disksubsystem, that the lun nr. is correct ? we seen all kind of weird things, like cable crossed,.....

Xserve won't boot from RAID after a Shutdown

Hello
I'm running a new Intel Xserve 2x2.0Ghz with Apple Raid Card an 3x250GB Apple Drives in.
Starting from 10.5 Setup DVD and setting up a Raid 5 using the Apple Raid Utilitie works fine an also the installation works great. Raid set is ok, Volume initilized, all up an green.
If I then power down the Xserve (to move in to a rack or so..) an power it up again, the raid setup is gone, no bootdevice. No raid sets nor volumes are available when checking again with the Apple Raid Utilitie from the setup dvd. Backup batterie is charged an I also replaced the raid card one time.
Has anyone an idea whats wrong with this box?
Best regards,
Christian, Switzerland

The EFI firmware, the SMC and possibly the disk I/O path seem good potential candidates for culprit.
Load and run the hardware diagnostics.
Reset the SMC, and reset the LOM.
I'm running the EFI diagnostic tool now. Firmware and disk I/O path came to mind, let's just hope it's not a major hardware issue

Xserve G4 Won't boot from Anything

Everyone:
I have a G4 Xserve (slot load) with 2 GB of RAM installed. It was running X.3.9 just as happy as a lark. I migrated all users from the server to use it as a test environment. My first test was to upgrade it to Tiger, which so far has not gone very smoothly.
The Xserve has all 4 bays populated. Bays 1&2 are mirrored using Apple's RAID software, this is the system drive. Bays 3&4 are set as a RAID 0.
My Upgrade goes like this: I inserted the Tiger Server CD (no DVD drive), double-clicked the installer and the server rebooted. The installed seemed to go smooth, but I did have to walk away from it towards the end. When I came back, the server was stuck at a blue screen and a moveable mouse pointer. Couldn't do anything else.
This forced a hard reset, of which the same thing happened. So I thought, no big deal, let's just redo the installation. Insert Tiger CD again, hold down C key....server boots from hard drive and gets stuck.
Weird.
Ok, let's try booting from the Panther CD. Reboot server, hold down mouse button, eject Tiger CD, insert Panther CD, reboot, hold C key....server boots from hard drive and gets stuck.
Dang. This was supposed to be an easy upgrade.
Just so things aren't confused, I pull out the drives with the Raid 0 (Bays 3 & 4). Same process.
OK, maybe it's the Raid on the system drive, so I pull out one of the drives. Same boot process.
Reset the PRAM, just for grins, no change.
Alright, let's see if I can force it to recognize the CD, pull out all the drives and put in a spare, brand new drive from the shelf.
Same thing, won't boot from CD. Neither Panther or Tiger. At least I get the blinking icon that there's no OS installed.
Put the #1 system drive back in, connect an external firewire CD Drive, still won't boot from CD. I still get to a blank blue screen, though.
Try booting in Single User Mode, I still get the same thing, boots from disk to blue screen.
Now I've spent an afternoon of my time and another techs time and we're both scratching our heads. I recalled that I could also issue boot commands via the Sys ID button. Dig out manual, find the combination, same story. Boots from hard drive to the blue screen and stops.
Seems like any input at boot time is being ignored, although it will eject the CD if the mouse is held down. I've verified that the machine is not locked (the light is off). I also opened it up to make sure that the lock switch wasn't partially stuck. Not sure if there's anything else to check.
Thoughts?

does that mean I have to send it to Apple to fix
No. Apple changes the bootROMs from model to model so you can't use the same install disc on different models. It could their way of dealing with piracy.
Example; Say I bought a new MacBook Pro and I had an iMac that was still running Leopard. I couldn't use the Snow Leopard install disc from the new MBP to install SL on the iMac.

Cannot boot from RAID 1 drive on K8N Neo4

I am trying to install Win2K on a mirrored RAID array my K8N Neo4 motherboard. Here is all the hardware:
K8N Neo4(MS-7125). The box says K8N Neo4 F, but the intro screen says "Platinum". Bios version 1.9
Hard drives: Two Maxtor Ultra16 250GB 7200 IDE drives. Both on IDE controller 1 as master and slave.
AMD athlon 64 3500
I followed the directions in the manual for booting off a RAID array.
In CMOS, Enabled IDE RAID, IDE Primary Master RAID, and IDE Primary Slave RAID.
In F10 raid setup:
Set up "Mirroring" RAID array using both drives.
Enabled "boot" option for the array.
Array list shows Array as healthy.
Set boot order to "hard drive" then CDROM.
I boot from win2k CD, press F6 to install RAID drivers.
After a bunch of other stuff has been loaded, I am prompted for the RAID drivers. I load both exactly as shown in the manual.
However, I am not sure I have the correct drivers on my floppy. The directions in the manual for creating the floppy are clearly incorrect as they would result in nothing on the floppy. I coppied the contents of the "pataraid" directory to the floppy. The win2k installer asked for "nvata.cat" so I took it from the "sata_ide" directory.
Next, the installer asks me which disk I want to install windows onto. This seems strange as it should see the two disks as one drive.
I tell it to install on the forst drive. It formats the first drive and transfers a bunch of stuff. It then reboots and tries to boot off the hard drive (or RAID array in this case). The computer is unable to boot off the hard drive.
Has anyone seen this?
What should I really make the RAID driver floppy?

I think I know what you are referring to. Nvidiia's documentation for nvRaidMan says that it reconstructs a mirrored array (once the bad drive has ben replaced) slowly over the period of a day. I think this is actually a disadvantage. The promise RAID controller allows you to immediately copy the good drive to the new drive. It can take a while for big drives (like twenty minutes), but then you are fully protecetd again and you dont have this big task in the background all day long. More importantly, the promise documentation makes it clear which drive is being copied to which.
I think I will start looking for a promise RAID controller and just make a mental note not to trust nvidia.

Server won't boot from RAID mirrored pair

Some months ago we updated an OS X 10.4.7 server with a software raid pair of disks to 10.4.8 and were rewarded with a machine that sticks at the black-on-grey Apple logo with no cog wheel displayed. At that time I just bought a couple of new and larger disks, reinstalled OS X Server, updated with combo updates rebooted a couple of times to be sure and all has been well until tonight when our system manager tried to install Retrospect which required a reboot and, suddenly it's hanging at the Apple Logo again. Such cruel irony...
Booting from the install CD I can mount the raid, and apart from a handful of permissions needing fixing, Disk Utility says the pair is fine. Although Startup Disk lets it be selected as the startup volume, the problem persists and still won't boot.
Does anybody have any thoughts as to how to cure this problem reasonably quicky in way that preserves as much as possible of the existing installation. My only idea is to try bless(8) to fix the boot behaviour of the volume. However, its man page doesn't discuss blessing raid mirrors. Is there anything special required?
I'd also like to know what caused the problem in the first place, and how to prevent it in future.
Thanks
Charles

You say it has been working so I can't really tell you why it acts up now.
But the raid was setup using 10.4 Disk Util (RAID ver. 2 sw.)?
Tried diskutil checkraid disk3 in Terminal (from DVD)?
Tried running DiskWarrior?
A customer who bought a pair of new larger third party drives for his Xserve G5 and put them in his old 250GB drive bay carrriers couldn't get it working with sw RAID (I didn't look at it myself).

Unable to boot from cloned MacOS 10.6.8 server

Hi there,
we've successfully restored a MacOS 10.6.8 server image to an Intel Xserve. However, there seems to be a boot cache issue. Sometimes I am unable to boot and MacOS Server won't restart. The Xserve restarts twice on the gray Apple screen. Than it's hanging on the gray Apple screen. no disk activity for minutes. I've waited 30 minutes. I had to power down the server. After that the server boots normally. no errors in verbose mode during startup.
I am using 3 volumes (all 3 using the same system clone). All Bay drives using the original Apple Disks. They are brand new. <29 hours.
Resetting the NVRAM a couple of times didn't solve the issue. The booting error is reproducible. This system runs fine and it's really clean. I just installed the latest MacOS 10.6.8 combo Update
I don't know what else I can I do? I really appreciate any help on this.

Sorry for the delay in responding.
Thank you, Peter. The Xserve running fine so far. We've had any boot issue.

G5 xserve: How do I boot from a FireWire device ?

Hi.
I have a PowerPC G5 server WITHOUT a keyboard/display and have just installed Leopard 10.5.1.
After setting up Leopard, I made a backup copy of the server HD onto a Lacie FireWire hard-drive device connected to the FireWire 400 port on the front-panel using Carbon Copy Cloner v3.
The backup appeared to work fine.
However, when I tried to boot from the FireWire device by holding down the system identified button at the same time as the on/standby button and then selecting Light 4 (to quote page 65 of the G5 User Guide… “bypass the current startup disk and start up from any other available startup disk”) nothing happened. Instead, the fans just got louder and louder and louder and louder, with the occasional flash of FireWire device and HD lights. I switched it off after 10 minutes and re-booted as normal from the HD device.
Any suggestions ?
Thanks in advance,
john

Tony,
Having thought about this and read Apple's article "how to use FireWire target disk mode" (http://docs.info.apple.com/article.html?artnum=58583), let me play back what I think have to do...
Assumptions...
a) A working Leopard system.
b) I want to go back to yesterday's backup.
c) I can't use Time Machine as it's an "Advanced" install.
d) My backup is done via Carbon Copy Clone onto my external FireWire device.
Is this what I would do... ?
1) Get my PowerBook G4 laptop, which is also running Leopard !
2) Switch off the Xserve G5.
3) Connect the FireWire backup to THE LAPTOP !
4) Connect the laptop to the Xserve using a FireWire cable.
5) Switch on the G5 and hold down the system identifier button.
6) When the lights rotate select Light 5 "Begin target disk mode".
7) On the laptop an icon would appear which is the Xserve HD.
8) Using the laptop, I then copy from the FireWire backup to the Xserve HD icon.
(I guess, as the fans may be running flat out at this point !)
9) After the backup then eject the Xserve HD icon.
10) Disconnect FireWire cable.
11) Re-boot Xserve
12) Should be running yesterday's backup.
13) Relax !
Blimey !

XServe G5 doesn't boot from OSX 10.5 Server Install DVD

After a long and rather happy life with 10.4 Server on my XServe G5 I decided I'd like to check out the ical Server and the other goodies in 10.5 Server.
I still have installer DVD form my maintenance I bought with the XServe.
XServe G5 10.4.11 runs headless, I have ARD
Admin computer is a MBP 17" unibody (INTEL) runing OSX 10.6.2
A few problems:
Admin tools 10.5 cannot be installed on my MBP -
I downloaded the Admin Tools for 10.6 they 'should' work for this but
I wasn't able to connect to the XServe due to other problems:
Here what I tried:
Insert OSX10.5Server Install DVD into XServe G5 -> gets ejected (no clue why or where to check why)
Insert OSX10.5Server Install DVD into external FW400 DVD drive -> is mounting, can be chosen as startup drive but reboot always ends up booting from installed 10.4 Server OS.
I also tried doubleclicking the "INstall OSX Server 10.5" Icon when the DVD was mounted but same failure, XServe boots from internal system rather than from install DVD.
Any ideas what I might be doing wrong ?
Any hints how to "service" the existing istallation so it will allow to boot from external (or better internal) DVD drive ?
Any help is greatly appreciated.

The trouble with a headless G5 is you can't see what happens when holding down the option key at boot but an external DVD-drive (if needed) must be firewire on a G5.
An Open Firmware reset sometimes make the computer find firewire drives afterwards.
We have a customer running iCal server for 10-15 people on such a machine but the RAM is "upped" to 5GB. It is also running FileMaker server 10 and filesharing. + Retropect 6.x "Backupserver".
You can run with non-ECC RAM (PC3200) in that Xserve.
It could work OK but expect 100% CPU periodically mostly because of running Python scripts for iCal server.
Keep calendars fresh - don't import/save/keep old events for years back in them.
10.5 iCal server It can't handle too many events in one celandar (1500 max I belive someone found out by testing). I can take "forever" syncing calendar with many events.
iCal server in 10.6 is revised for less resource use.

Bootcamp woes, unable to boot from USB and DVD drive reads all DVDs blank

My partner and I are completely unable to install Windows using Bootcamp. We have tried dozens of solutions on the internet.
2011 iMac (purchased in by me and my partner 2012) reads all DVDs as blank. We have (hilariously) another Mac, an MBP, that has the same exact problem. You'd almost think "Superdrives" eventually just stop working or something. So obviously we can't install Bootcamp on the iMac using a DVD.
But what about a USB stick? Well after modifying the plist file and writing a bootable Windows USB and trying to boot from that, we were greeted with the mysterious and apparently yet-unsolved "no bootable device" error.
So our iMac can't boot from USB drives or read DVDs. We've only owned it for two years. And this is the second Mac we've owned where the Superdrive has died. And we don't even use DVDs more than like once a year.
But anyway, can someone tell me what we're supposed to do if we want to install Windows aside from throwing money away to buy another Superdrive that is probably going to die again in a year? Maybe a way to make our mac boot from our USB stick? Something?
Thanks.

Should you have another drive with a MBR, use it to rule that issue out. Alternatively create a GPT on the flash drive and try to boot from it.
What options are there for the usb controller/boot priorities/order/options? Does the laptop recognize the usb flash when already in bios setup? Should there be any form of choosing the device to boot, use that with the flash drive in the socket, then switch it with the external drive.

Booting from RAID 0

I have set up my Mac Pro to boot from a RAID 0 created from two WD 500 GB RE2 drives. Everythings works great - but - after running bootcamp, Windows XP does not see the Mac startup volume and I have to option-boot when restarting to get back to the Mac. Rebooting the computer also goes into Windows requiring the an option-boot menu. Anyone else have this problem or a solution?

You need to go to OSX and set the boot drive to the Mac Volume. Then, when in Windoze, select the Mac Volume when booting back to OSX.
If you still have issues I would:
a: Repair Permissions
b: Reset-PRAM, this will reset the boot drive to OSX
c: Repair Drive with Disk Utilities (Mac Drive)
d: Try re-installing Boot Camp
I do not have this issue with non-RAIDED drives but had it with a regular dual partition drive... It got mixed-up and did the above.
The previous poster is probably correct, he has the same basic set-up as you do. Would not hurt to try though.

Boot from Raid-hdd with a controller card installed?

Hi,
I have a problem. I've just intalled a Windows 2000 my HDD3 (IDE-raid) and everthing went well. I've put the 1st boot option to SCSI and it boots normal. But when I add a hdd to my controller card (Promise Ultra100) it doesn't boot the raid, instead, it tries to boot from the hdd on the controller-card. I've just got this card, and had a KT3-Ultra ARU before. There I could change between "Ultra-0, Ultra-1, Raid-0 and Raid-1 etc. etc." in the bios, where Ultra stands is the Controller card and Raid in the onboard raid. So, why can't I do this on this, newer card? Any1 know how to work around it or how to fix it?
This is what I have:
IDE1:
Master: Western 180GB
Slaev: Maxtor 250GB
IDE2:
Master: NEC 1300A
Slave: Lite-on-it 40125W
IDE3 (Raid):
Master: Maxtor 80GB
Slave: Maxtor 80GB
Controller card IDE4:
Master: Western 250GB
Slave: Western 250GB
Controller card IDE5:
Master: Western 200GB
Slave: Seagate 30Gb
Controller card = Promise Ultra100
And yes, I have the modded version of the bios couse I wanted to have a real raid on my IDE-drives. How can it even be raid if it's only one drive? But that doesn't really matter, couse the boot-options are the same as before.

Hi, I did as u said and bought a new controller card (Titan Electronics Inc. Ultra ATA/133 IDE). But it didn't help, it's the same as with the older Promise card.
This is what happenes:
When I add a hdd to the controller card it finds the hdd and such. Everything works normal untill the os-boot-process begins. Because there is only one alternative called "SCSI" in the bios, where u chose where to boot from it thinks it should boot from the controller card (cause it is a kind of SCSI-card). But I want it to boot from the raided-drivers on the onboard raid (whitch also is a kind of SCSI-card). The thing is that it mixes them up, and only tries to boot from the controller card i've installed, and ignores the raided-drivers. When I had my Kt3 Ultra-aru I could chose between booting from:
IDE0
IDE1
IDE2
IDE3
CDRom
Raid0
Raid1
(this options only showed up when I had my Promise ULTRA controller installed on it)
ULTRA0
ULTRA1
ULTRA2
ULTRA3
But with this, newer and more expensive card, I can only chose SCSI in the boot sequnce.
Any idea how to fix that? Maybe to mail to the MSI so they fast can added that choice to the BIOS in an update?
Would be thankfull for any help possible

645E MAX2-LRU Can I boot from Raid?!

Hello,
Is it possible to boot from the onboard RAID?
I'm not sure cause I can't boot from any HD that is connected to the RAID IDE when I use them in "non Raid" mode.
I have an entry in the Bios "boot device" where I can set "Legacy SCSI". Is this the entry for the RAID Controller?
THX for your answers and excuse me for my bad english!!

Some more interesting information is had in this article about the virtues of SoftRAID vs. OS X RAID.
I've got backup to my backup. Call me paranoid if you like, but I hate standing there looking like a horse's tail end and crying about lost data and irreplaceable applications because I didn't do some simple housekeeping.
Add me to the "tri-backup" team (the wife hates all my hard drives.... sees money spent, I guess....).
I also keep 'hard copy" DVD of archived data, and all photos and audio. It only takes losing some important data once to underscore the importance of backup. In my case, it was a near miss (was able to scavenge the SCSI drive), but it scared the bejeebers outta' me......
