Unable to boot from cdrom in single user mode

I have lost the root password for solaris 9.So, I tried booting the system with solaris 8 CD in single user mode(i.e, at ok prompt, boot cdrom -s)
But I get the following error.
rebooting with command :boot cdrom -s
boot device :/pci@1e,600000/ide@d/cdrom@0,0:f file and args -s
boot:cannot open kernel/sparcv9/unix
Enter filename:[kernel/sparcv9/unix]:
Please let me know why is this error?.Is it becos the CD is corrupted?

Also, the particular Solaris 8 you've chosen could be a distribution that's too old for your particular computer's design.
For example, a Sunfire V440 would need Solaris 8 HW 7/03 or newer.
http://sunsolve.sun.com/handbook_pub/Systems/SunFireV440/Sun FireV440.html
Solaris 8 HW 2/02 would not work.
What model system, and what version Solaris are you trying to use?

Screen resolution at boot time and in single user mode?

Hello!
I remember back in 10.3.8 or earlier my Mac booted right away in 1280 by 1024 pixels screen resolution, thus avoiding the video mode change when showing the progress bar.
I didn't manage to get it back to work this way.
Reset NVRAM ( a zillion times!) didn't help, nor did setting the screen mode from the admin or root account.
I'd really like to have it back!
It's no fun working in single user mode on 640 by 480.
I know this has been working with the original ATI Rage 128 and with the Radeon 7000 PCI I built in 3 years ago.
Any ideas?

Powermac G3 b/w Rev. B Mac OS X (10.4.7) RAM: 896 MB

Not sure if this is related enough, but I just wrestled trying to restore from time machine too, trying to reinstall 10.5.8 after putting a new HD in my MBP, 2006 vintage.
That took sooooo long to get back to where I was before swapping disks; what did the trick was ordering a free copy of Snow Leopard install disk (free due to Apple trying to push people from idisk to icloud) which was rushed FedEx (yay) and which allowed me to access Time Machine where my ancient original OSX install disk had not.
And all it took was 2 weeks of cursing!

Can not book from DVD or Single user mode

Hello,
In a bit of a pickle here. I have an ibook g3, 10gb hard drive, 512mb ram, cd/dvd combo drive and an airport card.
When i book up the system I get the broken folder icon (the flashing ? mark) I have tried to get the system to boot from a DVD of Mac OS X Tiger. However no matter how long I hold the C button down it will never even try to boot from the DVD.
Also no matter how long I hold down Command + S it will never go into the single user mode. However I know that the keyboard is good because I have been able to reset the PRAM with CommandoptionP and R and I get the normal two chimes. No luck.
I have reset the PMU out of desperation. I have even installed a new keyboard from a working ibook.
I know it would be easier to just buy a new mac but this isnt an option for me due to money issues so I want to fix this system. Also I do not have a double ended firewire cable for target disk mode.
My question is what do you do when you cant get past the broken folder and when it does not even try to load the Mac DVD?
HELP ME PLEASE!

Have you tried booting into Safe Mode? If not, I suggest that you give it a try. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up in Safe Mode, try to restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if you are able to do a little hard drive maintenance to help things out.

IBook Mac OS 10.3.9 not booting, even crashing in single-user mode

Yeah so about 2 weeks ago my iBook started crashing, then wouldn't properly re-boot. Gradually, it would start crashing after being on for less and less time until now it gets just past the apple symbol and then freezes on a blue screen.
I've been using the online help but now it's even freezing during single-user mode, meaning i can't even perform fcsk!! I can't even boot up on the Mac OS X CD to re-install the OS. Anyone got any idea what's wrong or what I can do? Thanks, Rob

What, exactly, is preventing you from starting up from the Mac OS X install disk?
Have you added any RAM yourself? You might try taking it out to see if that helps. You might also try to run the Apple Hardware Test. Depending on which bundle of install disks you got, it may be on the Mac OS X install disk or it may be a separate CD of it's own. It should be marked "AHT" and a version number on the disk. Put that disk in the drive, restart and hold down on the "option" key. This will give you a Startup Manager that should allow you to select the hardware test and continue (click the right arrow to continue). If you can't even get that far, then you probably have a hardware failure and you'll need to take your iBook in for service. What is your location?

Can boot to disk in single user mode. But not regular boot.

I setup an alias called md-rootdisk for booting my Solaris 10 System on a V440.
I tried to reboot using the alias md-rootdisk twice. It only worked once.
The first attempt was to single user mode. The sytem booted but there was a krtld error.
The Second attempt was a regular boot.
I'm trying to figure out why the first attempt "worked" and the 2nd didn't.
The details are below.
First Boot_
{1} ok boot -s md-rootdisk
Boot device: /pci@1f,700000/scsi@2/disk@0,0:a File and args: -s md-rootdisk
krtld: Unused kernel arguments: `md-rootdisk'.
SunOS Release 5.10 Version Generic_120011-14 64-bit
Second boot_
{1} ok boot md-rootdisk
Boot device: pci@1f,700000/scsi@2/disk@0,0:a File and args:
Can't locate boot device
{1} ok boot md-rootdisk

If the disk is a normal disk, this will get you to single user mode:
boot disk -s
In the second case, it looks like there is something wrong with the device path aliased.

Unable to boot from CDROM

Hello,
Configuration
Msi 6380 - K7T266Pro2
Bios 3.6
Processor Athlon XP 1600
Ide 0 40Gig Maxtor
Ide 1 CDROM SONY CRX140E-BP
Ide 1 DVD LG DRD-8120B
Recently I wanted to install Linux Mandrake 9.0 and I found out that I couldn't boot from the cd rom, the bios seems to recognize both players (cdrom and dvdrom) but i couldn't boot from cd rom.
after changing everything's position in the system the problem remained. I have also a second computer wich only have one cd rom player an LG cdrom player.
I changed the sony with the LG cdrom player and suddenly I could boot from cd rom. Now I have 2 questions.
1st why can't I boot from my sony cdrom player/writer ?
2nd my dvd rom player is stated in bios as DVDROM and there is no option to boot from DVDROM, is it possible to change this in newer bios versions ?

first of all, set your DVD/CD-ROM devices as "CD-ROM" instead of "AUTO" in the BIOS - Standard CMOS Features. Then only proceed with the boot sequency settings.
Hello,
I don't seem to find this option in my bios, I only have auto, settings 1-46, armd and user
I suspect this sony cdrom/writer has problems with dma
does anybody know of other problems with this cdrom, does anybody has this cdrom and has no problems ?

Network driver attachment booting cdrom single user mode

I am attempting to boot from cdrom in single user mode and reach some network shares. However, when I boot cdrom, the server does not attach the network drivers, meaning I cannot plumb up any of my interfaces.
Now, I should add that we have an XVR-300 card in an XAUI PCI-E slot. I read somewhere that this can disable one of your network ports, but shouldn't it still see the other ports and attach the network drivers?
Any body have any ideas or anything I could try?
Thanks!

IMac 7,1 boot only in single user mode

Hi all
I've a colleague with the following problem... his iMac 20'' (iMac7,1) is able to boot ONLY in safe/single user mode (with shift key pressed during boot).
If he tries to boot normally, after the usual Apple logo screen he gets a blank (light grey) screen. No finder, no login screen.
We've tried this procedures:
- SMB reset
- PRAM cleared
- OS Reinstall (we've tried from Lion to Mavericks... actually there's 10.7.5 installed)... note that ALL installation procedure has completed successfully.
- tested the 1 RAM module installed (seems to be OK)
- tested the HD (no problems found)
Despite all these attempts, this iMac is booting well only if we press SHIFT during startup. All programs run well, wifi is working and online update too. If we reboot leaving it to restart normally (no key pressed) it shows Apple Logo for 1 minutes, then (after a black reset of the screen) seems to crash/stuck into an empty grey screen.
Is possible to identify which driver/kext is causing this problem? It can be an hardware problem? How we can fix it?
Thank you!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Automatic scrip execution on the console in single user mode on Solaris 10

Hi All,
On Solaris 8, I am able to launch my script automatically on the console when the system comes up into single user mode without having to enter the password. However, on Solaris 10, the script is display in the foreground on the console. When i do a ps -ef , I see the process running. Can someone please tell me how to get this to work on solaris 10?
To automatically boot the system into single user mode:
# svcadm milestone -d milestone/single-user:default
Files edited for this to work on solaris 8:
To login without a password:
# cat > /etc/default/sulogin <<EOF
PASSREQ=NO
CONSOLE=/dev/console
ALTSHELL=YES
EOF
# echo "/sbin/su -" > /sbin/rc1
(Solaris 10, I used rcS instead of rc1)
my script is called from the /.profile when the system comes up into single user mode.
I did the same on solaris 10, but no success.
Please let me know if you have any suggestions.
Thank you,
Brian

try
- add 'set -x' to your /etc/profile
- add 'set -x' to /etc/rc? scripts
- check /etc/vfstab for a nfs mountpoint not using 'bg'

Difference between emergency state and single user mode ?

Hi,
I want to know the difference between emergency state which we normally use in suspect mode database and single user mode.
Navakanth

Emergency/suspect mode is tells you the state of the database and database is not available for user action but where as single user mode tells the user action preference. Database is active and available for the user action.
You can refer
http://msdn.microsoft.com/en-us/library/bb522682.aspx
EMERGENCY
The database is marked READ_ONLY, logging is disabled, and access is limited to members of the sysadmin fixed server role. EMERGENCY is primarily used for troubleshooting purposes. For example, a database marked as suspect due to a corrupted log file can be
set to the EMERGENCY state. This could enable the system administrator read-only access to the database. Only members of the sysadmin fixed server role can set a database to the EMERGENCY state.
SINGLE_USER
Specifies that only one user at a time can access the database. If SINGLE_USER is specified and there are other users connected to the database the ALTER DATABASE statement will be blocked until all users disconnect from the specified database. To override
this behavior, see the WITH <termination> clause.
The database remains in SINGLE_USER mode even if the user that set the option logs off. At that point, a different user, but only one, can connect to the database.
Before you set the database to SINGLE_USER, verify the AUTO_UPDATE_STATISTICS_ASYNC option is set to OFF. When set to ON, the background thread used to update statistics takes a connection against the database, and you will be unable to access the database
in single-user mode. To view the status of this option, query the is_auto_update_stats_async_on column in the sys.databases catalog view.
If the option is set to ON, perform the following tasks:
Set AUTO_UPDATE_STATISTICS_ASYNC to OFF.
Check for active asynchronous statistics jobs by querying the sys.dm_exec_background_job_queue dynamic management view.
If there are active jobs, either allow the jobs to complete or manually terminate them by using KILL STATS JOB.

Keyboard completely unresponsive in single user mode

Since upgrading to v10.5.1 I have been unable to get both my Apple USB and Apple Bluetooth keyboards to work in single user mode. I can get into single user mode using the command-s keys but once there the keyboard dies. This is the only time the keyboard fails. I have no other USB device attatched. I am using the white (non-aluminum) Apple keyboards. I'm curious to see if anyone else has this issue.

It appears to have been a Bluetooth only issue. I got the USB keyboard to work in single user mode. However I had to first turn off Bluetooth before rebooting into single user mode. Originally I kept Bluetooth on before rebooting using my USB keyboard. This for some reason prevented the USB keyboard from functioning in single user mode. When I have some time I'll further troubleshoot the Bluetooth keyboard issue and report back.

Mount external Hard drive in Single user mode

Do any know how to mount an external hard drive in single user mode:
I've issue the following command:
/sbin/mount -uw /
mkdir /Volumes/ex1
/sbin/mount_hfs /dev/disk2s3 /Volumes/ex1
(I've checked my external hard drive using df -k showing the device is disk2s3)
Result:
Permission denied

I seem to remember the "Permission denied" or "Device busy" coming up in some situations but not others when attempting to mount drives at this early stage in "single user" mode...
It might be worth trying to run:<pre>sh /etc/rc</pre>This is actually present among the "Tiger" messages in "Single User" mode, as the procedure to continue booting but remaining in "single user" mode. Indeed, it seems to start up the usual "services" like starting disk arbitration (so you can eg. use 'diskutil' to repair permissions, or loading "NetInfo" so you don't need to work in '-raw' mode - in the past, people had posted complicated procedures for doing these things manually.
After running the 'rc' script, try creating your mount point and and running 'mount_hfs' as usual...

MacBookPro does not start in Single User Mode

I am trying to boot my MacBookPro in Single User Mode. I read I should power off computer then start it while holding Command-S. I don't know what I am doing wrong but whenever I try, Mac just load normally and load the system.

Nevermind, seems to be working now!

Bazzar Behavour? single user mode

If I boot my G5 into Single User mode, the fans will slowly pick up speed and seem to go on getting faster and fastr. On exiting S/U mode and mounting the full desktop the fans will return to normal.- it's only in s-u mode that I have this problem....
Is there a daemon or other which checks and controls these fans,- and is it not working in single user mode? any diagnostic tools I should use to check temps and fan speeds?
much love,
Alex.

The fans are software controlled, and the software which controls them is not active in Single User mode; in this case, the fans will go as fast as they can.

How to mount USB & CDROM drives from single user mode - Solaris boot disk?

Hi All,
I need to carry out ufsrestore on a single newly replaced system disk (no redundancy / mirroring) from either USB or CDROM drives from the following steps:
( i ) GRUB => e, e, cdrom –s, Enter, b (boot from Solaris 10 x86 media).
( ii ) Choose menu 1 for Install Solaris Interactive Mode to reach single user mode.Below are the commands that I have tried in single user mode without success:
mount –r –F pcfs /dev/dsk/c1t0d0p0 /cdrom (after unmount Solaris CD)
mount: /dev/dsk/c1t0d0p0 is not a DOS filesystem.
svcadm –v enable smserver
svcadm: Pattern ‘smserver’ doesn’t match any instances
svcadm enable autofs
svcadm: Pattern ‘autofs’ doesn’t match any instances
devfsadm
devfsadm: mkdir failed for /dev 0s1ed: Read-only file system
mkdir /mnt
mkdir: Failed to make directory “/mnt”; Read-only file systemPart of the problem is due to the current READ ONLY filesystems which does not allow the creation of mount point such as /mnt.
I have been able to create both / root (/dev/dsk/c1t0d0s0) and /export/home (/dev/dsk/c1t0d0s0) filesystems with newfs that are awaiting for restore using ufsrestore.
The only option I am left with is to attach a secondary disk to install Solaris 10 on either of them before bring the system to multi-user mode so that service such as volmgt, autofs, volfs are available to access USB & CDROM drives.
Any suggestion on how to resolve this issue?
Many thanks,
Jack

Hi JKGN,
Is the directory a located under the root filesystem. ie /a? Are there any other mount point for say USB drive as well? I am not in a position to try it out right now but will get back
to you soon on whether /a exist or not.
Btw, the last thing I managed to do on this system at the time was added a secondary 1TB internal disk with the intention to restore both / and /export/home data onto this disk while
making use of all the disk device management services such as the following services only available in a fully installed Solaris system (both single & multi-user modes) installed on the
primary disk:

        Device Type: DVD Reader/WriterHowever, I was disappointed that "iostat -En" has not found the secondary disk (1 TB) even though it was available earlier, for Solaris installation as the only disk on the same system.
As a result, I am left with no option but the need to rebuild this system with only a single primary disk while in single user mode. However, the single user mode that I am in is the
one from Solaris installation disk with restrictive (_cannot create folder for mount point or running disk management utilities_) capability such as those services just covered, compared to one from a completed Solaris installation system with full access to all filesystems and utilities / commands in general.
I would very much value your assistance on how to mount both CD & USB in this restrictive limited Read Only OS (assume that it is running from memory) in order to get complete access to
the blank primary disk so that full restore with ufsrestore could take place.
Thanks in advance,
Jack
