Safe boot from raid1 system disk? Still recommended for updating OS?

Is it possible?
If it is how?
My MP just reboots or hangs.
Is safe boot still better way to update OS in .5?
GUI is disabled anyway in "normal" update procedure and maybe same services than with Safe Boot?

Xserve G4 (slot loading) not booting from a system disk - HELP!

I've read through the support and learned that when booting from a disk that the Xserve wants to load resources into the ram, therefore taking a long time to boot.
I waited over 40 minutes and still the Xserve did not boot up.
Was I too impatient? Should I have waited longer? How long? Or can I bypass this?
I need to repair my hard drive but because of this issue haven't been able to touch the drive.
Thank you for your help.

Hello pkchoo, and welcome to the Appleboards,
Forty minutes sounds like too long to wait for even a G4 from a CD drive but I've never booted one that way personally. If the internal drive is really dead that can sometimes hang booting from even a known good source. If you pop the drive in question does the machine boot then?
Other things you can try are booting from an external firewire drive or booting the Xserve into Target Disk mode and attaching another computer (like a notebook) to the firewire and checking the disk as an external drive. There should also be (I believe this is true for all Xserves) hardware evaluation and testing disks that you can use to see if the long boot time and troubles are perhaps more than just drive trouble.
Good luck,

Should I boot from external hard disk and how do I achieve this?

I'm in a downward spiral and need advice about if booting off of an external hard disc is the right thing to do and how to go about it. How I got into this mess I'll write below. My immediate problem is that I want to be able to install a copy of osx 10.5 from the original disks that came with my computer onto a usb hard drive. Then I want to boot from that drive and install software such as disk warrior on the same external hard drive in order to repair and recover the files on my internal hard disk. Not sure if this is easy to do with the install disk that came boxed with my macbook. So is what I want to do feasible and how do I do it? Thanks.
How did I get into this mess?
For those with time to read more. A downward spiral (and my macbook was working fine)::
I have been backing up my work documents onto a 20 GB pendrive waiting to get the money to buy an nas to work with time machine for the two macbooks we have at home as a place to backup photos and video. I bought a network drive but it wouldn't work with my macbook; my time machine backup freezing at 3 gb, but works fine with wife's macbook pro.
I tried to do TM backup on a usb hard disk and got the same problem. Support forums indicated that hard disk problems could confuse TM, so although I was experiencing problem free computing I ran disk utility from internal osx. This indicated an <invalid node structure - file system verify or repair failed> at the checking catalog file stage. So I followed instructions to run disk utility and repair from the installation disk. When I ran disk utility from installation disk I get exactly the same <invalid node structure - file system verify or repair failed>. It gets worse.
After failing with install disk utility, I could not then boot from my hard disk (I had had trouble free computing up to my attempts to use TM) or eject the disk. At first attempt I had no option but to boot from dvd again as hd not offered as an option. Second attempt hd option available but fails. By reading advice given to others I managed to eject the dvd and have tried:
safe boot - it won't
boot in verbose mode and single user (indicates I have disk0s2:I/O error) and won't boot
try to use disk utility from install disk to create disk image on external hd, it won't (cites i/o error)
If I can boot from an external I will try to repair with Disk Warrior as forums indicate that this software has been able to solve <invalid node structure> issues (but am open to recommendations of other products). I also hope that I may be able to try again to burn a disk image sucessfully if this repair works. I'm still trying to save my photos and videos that aren't backed up.
I plan to try an archive and install installation but first I want to try a repair with disk warrior as I fear that archive and install won't work and I'll end up having to erase and repair my hard disk.
I feel like some perverse god is punishing me for trying to do the right thing and back up my hard disk.
Macbook 5.1 late 2008
Intel Core 2 Duo
OSX Leopard 10.5.8
85 GB of a 150GB hard disk needs backing up (saving)

I am not sure about this, but my memory is that if you try to partition the drive (in OS 10.5.8) it will erase the data.
But you can try. Go through the Add a partition steps, but watch for any warnings. If my memory is correct there will be a message to the effect that everything will be erased. If you see that, do not proceed. This page has info about how to do it, if it can be done: http://www.macworld.com/article/1164643/live_partition.html
With respect to DW on an external, I do that. I have a 80 GB external - I call it Emergency - with an OS, DW and TechTool Pro on it. (Since I have is a recovery partition built in with all new OS, Emergency would be of use only if I need to run DW or TTP.) I have never yet had to use it, but it's there. It is not usually connected - I just did that for this screen shot.

RE: HP XP Media Center 2005 Ed will not boot from HP System Restore CD's

RE: HP XP Media Center 2005 Ed will not boot from HP System Restore CD's.
The following instructions about the "Code Purple" error FAILED. Error is still present.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
***PLAIN ENGLISH QUICK AND EASY FIX FOR ALL SYSTEMS****
***Windows 7 code purple or Windows Vista code purple***
With the code purple error on the screen, press shift+f10 (the shift key and the F10 key (at the top of the keyboard) at the same time) to open a little screen called a command prompt. (So, you get a little black screen with white text that says something about your Windows verison first and a little ways down you'll see "C:\>".   It's all ready for you to start typing.)
Type the following line, just as you see it here...
notepad C:\hp\bin\checkdmi\checkdmi.cmd
so it will look like this
C:\>notepad C:\hp\bin\checkdmi\checkdmi.cmd
Press Enter.
You will see the text for the file listed in a window using a simple text editor.
Go to the beginning of the text. Press enter to make a space. Type this...
goto cleanup
So, whatever comes after, the first line looks like this...
goto cleanup
Save the file and exit notepad and restart your PC. You are good to go.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RESULT: Same error and problem.
So, NOW THE SCENARIO IS THIS...[ And A CHALLANGE TO ALL HP Software EXPERTS]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. The PC will not boot the System Restore CD's
2. The Original OS install and [HP_RECOVERY] disk sector has been severely damaged by
all of the following:
   A. Massive Virus Infections as shown by Kaspersky Virus Scan and cleaned up.
   B. The user had originally updated the pc to Vista Business Express Upgrade
       (Supplied by HP with the original purchase and warranty).
        (Prior to the upgrade, Media Center was working correctly.)
   C. The original OS product key(XP Media Center Ed. 2005) has been changed by the Vista Business Express upgrade.
   D. The destructve recovery done by PC-Doctor has done user file damage(s).
   E. All software, and possibly hardware could be corrupted & damaged by viruses,
   incomplete recovery, and the unknown failures and conditions.
To sum up, the system is locked in an unknown state, waiting for expert help.
(I can allow and manage to let someone diagnose, repair remotely using another OS i.e.Linux Opensuse 12.1, or XP Home ed if needed.)
SO IF YOU THINK YOU ARE UP TO THIS CHALLANGE, SEND MESSAGES TO DAVHPForum anytime. Thanks in advance!

Booting from a Firewire Disk backup - get Startup Manager to show FW disk

Hi all,
A hint that I have discovered whilst trying to create a backup on a Firewire external Hard disk and boot my eMac from it.
eMac 1.0GHz (ATI), OS X Tiger 10.4.7 and OWC Mercury Elite Pro 40Gb firewire external disk (Oxford 911+ chipset)
I created a bootable backup using both Carbon Copy Cloner and/or Rsyncx on the firewire disk, but with the same results each time - it woudn't boot from startup manager. I was careful to make sure that the disk was bootable and it would boot from the FW disk after selecting it in system preferences/startup disk and restarting. O.K so far.
OS X also offers an alternative boot method using the startup manager at boot time which you can enter by holding down the option key while turning on the eMac until the startup manager comes up. Normally it shows your "macitoshHD" and "repair" hard drives and you can select the preferred boot up drive. According to Apple help it should also show bootable Firewire disks, but I could not get this to happen.
After a bit of trial and error, I found this sequence reveals the FW dive.
. Make sure your firewire external drive is turned on and plugged in to a firewire port on your eMac.
.Power on the eMac whilst holding down the option key (The key with the apple and squiggley thing next to the spacebar)
.Keep holding the option key until the startup manager icons appear.
.Once the startup manager appears, it will take about 30 secs to 1 min to scan for drives.
. Usually icons showing your internal bootable drives will show along with a rescan and continue icon.
. To get the FW drive to show, hold down the option key and click the rescan button (the turned back arrow icon on the left)
.The system will then rescan and find the firewire drives and show their icons as well as the internal drive icons.
. Select the firewire drive (You did give it a unique name didn't you?) and the click the continue arrow on the right.
. Watch the FW drive activity light and you should see lots of flashing and there you are - booting from the FW drive.
I couldn't find any reference in all the help references to holding down the opt key to rescan, so maybe it is peculiar to this eMac?
Give it a try and be sure to let me know if it works for you.
Ian

OK JMVP, but there is something a little strange here.
After I booted the system whilst holding down the OPTION key, startup manager appeared and scanned for drives but only showed the normal internal drives. (By this time I had already released the OPTION key). I clicked the re-scan icon and same thing, still no FW drive. According to all the Apple help files it should show the external FW drive as well.
But, when I held down the the OPTION key and clicked the rescan icon again, it rescanned and showed the internal drives AND the FW drive. Maybe it's an undocumented feature of startup manager, maybe it's peculiar to the FW drive I'm using
I will try to update the firmware, but the manufacturers website says it doesn't need updating to work with Tiger. Other than this minor prob it already seems to be working OK. Just won't show up in the startup manager without rescanning with the option key pressed.
I did notice whilst searching the help files that there is another option to boot from external drives:
Hold down Option-Command-Shift-Delete keys during startup - this will Bypass primary startup volume and seek a different startup volume (such as a CD or external disk). It didn't work in my case.
Curious?

K8N Neo4 - Disk Boot Failure, Insert System Disk

Hello !
Up an runnung with my new MoBo - for details se below, thats good. But...
No matter how I change my BIOS settings, at startup I got the same message:
Boot from CD : Disk boot failure, insert system disk and press enter
When doing so, the PC is booting OK.
Quit annoying, so glad for any hint !
Greetings / Jan Björk

Thanks TheBigMan for your welcome message !
Glad the join the Forum, it´s great knowledgebase !
I´ve gone through the BIOS settings you are referring to. They are like this: (And have been so all the time)
1:st Boot device [Harddisk]
Hard Disk Priority [SCSI:0 Nvidia Mirror 115.03G]
So there must be something else, thanks anyhow !
I also wonder from where this message, "Boot from CD..etc", is coming, is it really from the BIOS ?
Greetings / Jan Björk

How to force boot from an external disk

My main start up disk has crashed. I have made a cloned disk using Super Duper that I have checked recently and the computer will boot from it. I also have another OS 10.6.3 on another internal disk.
I now want to boot from the cloned disk but the computer always defaults to the internal disk. I have tried using Start Up Disk in sys preferences. I have tried starting up with the option key held down.
Is there anything I can do to force the computer to start from the clone disk?
One other thing, I installed a 1TB Western Digital Caviar Black drive to replace the crashed start up disk but Disk Uitility won't initialize it.
The computer is a 2007 Xeon quad core on OS 10.6.8.
Thanks

I got this, I think I did it right, not much into the terminal

My imac wont boot from the install disk

My IMAC will not boot from the install disk.

Hello, your installation disk is running under OSX??? If no the media has a problem!!!
1. Restart your mac and hold the alt (option key) to select media to install.
2. Restart you mac and hold the "c" key to boot.
an other solution is to make a partition on the hard drive and put a restore image of the Mac os X Installation dvd inside it then Restart your mac nad hold the "option" key and you will see the partition with mac os x installation and you can make a new installation from there.

Hey. I have recently made an update on my daughters iMac, particularly the update OS X 10.9.4, when finished, its still asking for update and the same update stills remarked as ready in the apple update menu and remarked as 1 to go at the App store app. Why doesn't stop asking for update when its done like 5 times or more? Thanks for taking your time!

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Booting from a mirrored disk on a zfs root system

Hi all,
I am a newbee here.
I have a zfs root system with mirrored disks c0t0d0s0 and c1t0d0s0, grub has been installed on c0t0d0s0 and OS booting is just fine.
Now the question is if I want to boot the OS from the mirrored disk c1t0d0s0, how can I achieve that.
OS is solaris 10 update 7.
I installed the grub to c1t0d0s0 and assume menu.lst need to be changed (but i don't know how), somehow no luck.
# zpool status zfsroot

Appreciate anyone can provide some tips.
Thanks.

This is what I have in my notes.... not sure if I wrote them or not. This is a sparc example as well. I believe on my x86 I still have to tell the bios to boot the mirror.
After attaching mirror (if the mirror was not present during the initial install) you need to fix the boot block.
#installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0
If the primary then fails you need to set the obp to the mirror:
ok>boot disk1
for example
Apparently there is a way to set the obp to search for a bootable disk automatically.
Good notes on all kinds of zfs and boot issues here:

Safe boot from raid1 system disk? Still recommended for updating OS?
