Booting from alternate disk in Sol 10 x86 1/06

Hey all--
I'm trying to set up a mirrored root filesystem on an x86 box with two IDE disks. It's running solaris 10 1/06. I've done this plenty of times on sparc boxes, but only once on an x86 box and after the metaroot, I had to edit bootenv.rc to point back to the "first" disk to get it to boot. That was with an older Solaris 10 release.
I'm reading what I think is conflicting information from the SVM doc in the Solaris 10 book at docs.sun.com, various blog entries ( like this one from Mr Jelinek -- http://blogs.sun.com/roller/page/jerrysblog?entry=solaris_volume_manager_x86_root ) and I'm confused now.
My main question is, do I need to manually put bootblocks on the second drive? My disks appear to have identical x86 partitioning as well as Solaris partitioning, and don't contain the now-deprecated x86 boot partition.
Page 126 of the current (12/05) SVM manual says:
You must specify slice 2 of the disk as the device, and slice 2 must comprise the
entire disk.
# installboot /usr/platform/i86pc/lib/fs/ufs/pboot \
/usr/platform/i86pc/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s2but.. pboot appears to be missing in the latest Solaris 10 release.
So does anyone know what the current situation is? Do you need to put bootblocks on the second disk in the latest Solaris 10? And if so, how? :) thanks!

bad 12/05 SVM manual..bad! :)
If I had done the RTFM thing like one is supposed to, I would have seen this bit of information:
# man installboot
     The installboot utility is a SPARC only program. It is not
     supported   on   the    architecture.    users   should use
     installgrub(1M) instead.I assume "the architecture" here could be better written as "the x86 architecture" :)
and of course, this makes sense, since the Sol 10 x86 1/06 release clearly boots with GRUB. I suppose I should also get my learn on for the other binaries:
# man -k grub
bootadm         bootadm (1m)    - manage bootability of GRUB-enabled operating system
grub            grub (5)        - GRand Unified Bootloader software on Solaris
installgrub     installgrub (1m)    - install GRUB in a disk partition or a floppyI'll confirm boot-ability later today when I take the machine into the lab. But I think I'm on the right track.
This is a great forum and I've learned a lot by reading it. many thanks to all the posters!

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.
WARNING: /pci@0/pci@0/pci@2/scsi@0 (mpt0):
Disconnected command timeout for Target 1

WARNING: /pci@0/pci@0/pci@2/scsi@0 (mpt0):

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.

Booting from alternate disk

Hi there,
I have four disks on an x4170 running Solaris 10. Ive SVM mirrored c0t0d0 (boot disk) onto c0t1d0 as an active mirror, and I have also mirrored it onto c0t3d0 and detached the mirrors. I wanted c0t3d0 to act as a sort of Rollback disk which I could boot from should there be a problem with the root disk.
I have run installgrub and updated the menu.lst with:
title Rollback
root (hd3,0,a)
kernel /platform/i86pc/multiboot
module /platform/i86pc/boot_archive
and format shows:
Total disk size is 17833 cylinders
Cylinder size is 16065 (512 byte) blocks
Cylinders
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 Active Solaris2 1 17832 17832 100
But... I just cant boot from it. I can see it listed in the GRUB menu when I reboot and Im able to select it from the list and hit return, but the system still boots from c0t0d0. No errors are reported to the console so Im really not sure what the problem is.
Can anyone tell me what Im doing wrong? I guess my menu.lst entry must be incorrect but its baffling me. Any help would be much appreciated!

Is this system on UFS or ZFS.
Someone else posted a similar message to yours:
http://forums.sun.com/thread.jspa?threadID=5419612&messageID=10884721#10884721
So I'm doing some checking and it appears that UFS and ZFS use different menu.lst files.

IMac crashed! Only get partial boot from OSX disk one

Booting from OSX disk 1, goes as far as a blue screen with no icons or menu. Boot with D key for hardware test. Test ok.
At a loss what to do next.
David

Does Seem so, or the Internal Drive is so messed up it's interfering, try this...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Can't boot from hard disk or from windows 7 recovery dvd

I have a 970A-G46 motherboard.
I can't boot from hard disk or from a windows 7 recovery dvd.
If I move the hard drive to another PC, it boots fine.
If I put the DVD in another PC's dvd drive, it can be accessed.
This machine will boot from an Ubuntu dvd and I can then access the HD directories and the recovery dvd.
What do I need to do?
Help and thanks

"I can't boot from hard disk or from a windows 7 recovery dvd."
What is that DVD from? Is it from a previous computer of some kind? Same question for HDD and the OS on it.

Booting from new disk drive

After copying all of my old drive onto a newer one I want to have all the computers that previously used the old drive boot into the new one. I can see the drive on my main server desktop but cannot boot from it. Any suggestions or readings you can suggest?

Several questions.
What application did you use to copy the files? SuperDuper! (full disk cloning is free; a very good app by the way). Carbon Copy Cloner? Both of these apps will clone a disk and make it bootable.
Were you able to boot from this disk before?
Is this disk an external firewire or USB? As far as I know all Mac with a firewire port can boot from a firewire bootable disk. I think only more recent Macs can boot from a USB disk.
You mentioned server. Are you by any chance trying to do a NetBoot? After all this is the *Networking and Web* forum. If so then the Mac OS X Server forum might be a better place to ask about NetBooting.

Booting from instll disk taking forever

I am upgrading to Tiger doing an Erase and Install. When I boot from the disk it is sitting there with the apple and spinning wheel for like 15 minutes and still hasn't started up. Any suggestions.

Hi Big Brad;
What install media do you have? Is the generic Tiger media or was it issued for another piece of hardware?

New MacBook won't boot from external disk

I have a new MacBook that I am trying to boot from an external disk that had the system from my first gen MacBook Pro. When I restart holding the Option key, and select my external disk, the system restarts again and won't let me boot from that disk. Is there something different with the OS (10.5.6) that is installed on a newer MacBook that won't allow it to boot from the same OS from an older MacBook Pro?
Thanks

golferx,
Will any other Intel Mac boot from the drive? If not, it's possibly because the drive uses an Apple Partition Map (bootable for PowerPC Macs) instead of a GUID Partition Table (bootable for Intel Macs).
To check: open to Disk Utility, select the hard drive on the left, select the Partition tab and look at the text at the bottom right corner of the window under Partition Map Scheme. If it says anything other than GUID Partition Table, you will need to erase and repartition it as such before it will be bootable.
Just a thought. Hope this helps. Good luck!

G5 gets grey screen with logo then goes black, won't boot from any disk

Won't boot from any disk, already changed VRAM battery, no success. tried hardware disk once and ran a full scan, said error with Video, but now won't boot at all with any disk. Screen is choppy also(have pic). Thinking video graphics card? Not sure. Need help!

Hi bribiel, and a warm welcome to the forums!
It certainly sounds like the Video card from the little info we have, & that can certainly cause it to fail to bootup.

IMac 20" won't boot from AppleCare disk

Hello all,
I have a new (1.5 weeks) iMac iSight 20" and am thrilled with its performance (it does not have any noticeable noise, nor does it have any dead pixels). I have tried to boot it from the AppleCare disk (the one with TechTool on it) but it will not boot. I have used that disk to install TechTool successfully on the iMac HD, but it will not boot from that disk. The iMac will boot from the OSX install disk that came with the iMac, and I have done so in order to run repair permissions before and after updates. Is there something easy I'm missing regarding booting from the Applecare disk? I'm not new to Macs, but I am new to iMacs and OSX. Any help is greatly appreciated.

Hello all,
Acting upon the advice I received here, I called AppleCare. Although it took 32 minutes, they did finally agree that the issue was with the AppleCare disk, and they are sending me a new one. I did note one interesting thing. I visited MicroMat's web page to see what the most current version is of TechTool Pro, and it is 3.0.4. That is the version on my current AppleCare disk. I guess the incompatability must be with something else on the disk. Thanks for all the prompt replies and great advice.

If we reboot the quest domains now, it works.
It seems the disks are not ready at the
time the guest domains boot.
We see this on systems with many guest domains.
Is there any logfile, where we could find the reason for this?
Or is this a known issue?

Press F12 on boot to choose CD/DVD as a temporary boot device.
My hunch is that there's something wrong with the SSD itself, though.
Good luck.
Cheers,
George

Ibook g4 won't boot from install disks

Got an ibook g4 1.33 ghz combo drive from original owner w/install disks. I want to reinstall original system but it won't boot from install disk 1. Tried starting holding down c but ignores disk. Holding down option just gives me the HD. Install disk shows up on desktop and opens. Tried disk utility from install disk but it doesn't allow me to erase the hd. Is there anything else I can do? Thanks.

OK, so let us suppose that you have the correct disk, the possibilities are:
• the optical drive is not functioning properly. However, since the disk shows up on the desktop the drive is apparently reading it.
• the disk itself is the issue. It could the wrong disk, but let us assume it is not. It could be damaged so that it is no longer bootable, or it could dirty. I would begin by giving the disk a good buffing and see if that will encourage it to boot the computer.
Good luck.

How to boot from rescue disk

Hi,
I am running Macbook Pro, snow leopard 10.6.8
My resuce disk is based on 10.6.4
I tried to boot from rescue disk to repair the main disk.
I failed to boot from the rescue disk as my rescue disk (from CD) is not being recognized. I tried multiple options such as holding down "C", "c", "option" key etc while the system is restarting. Only the main disk was being shown as the bootable option (while holding down the option key when restarting) but not the rescue disk.
I verified that my rescue disk is good. Infact, I could boot a Lion MacBookPro using my resue disk.
Any inputs are appreciated.
Thanks
gb

It was 10.6.4 (Snow Leopard). It was the same as the rescue disk version.
thanks

Wich Sun machines can boot from SATA disk?

Hi,
I would like to know which (newer and older) Sun machines can boot from SATA disks.
I think this is a feature of the OBP - so the question is:
Are there any updated OBPs for older Sun machines to boot from SATA disks?
TIA
Bernd

Hi,
I am aware the limit with earlier openboot revisions that limit ATA drive size to +130GB>>( search the forum for previous threads on this topic ), I recommend using only
supported drives in Sun SPARC systems. What kind of project are you working on? That's my private test environment. Due to my limited budget I use only older machines there (for example, U10, U30, etc). I was thinking about buying a used V120 or something like that to replace my existing fileserver.
A V120 with two internal 500 GB harddisks would be perfect for that .
Looks like I've to wait until used T1000 are available to a reasonable price.
regards
Bernd
