Yes, I was on the console when I run the command, and I did 3 times since we are also working on a mirrored disk problem that time. The last 2 init 0 command I did was when the mirrored disk problem already fixed.
Please see attachment to see the logs...
I have written a daemon and want to make sure that it starts up again after the machine is re-started so I can quit manually doing it. Problem is I'm having difficulty understanding what to do with the init.d
Any help would be appreciated! (1 Reply)
Hi Expert,
I have encountered some problem with my SUN system. Everytime when i issue command #init 6 OR #init 0 it just logout and prompt for login again instead of rebooting the server when run init 6 and system shutdown when run init 0..

I know if a parent process exits before its child, the last one becomes orphan for a while and then is added to the children of Init process.
I'd like to know deeper
1 how the orphan becomes init process,
2 how init knows that from a some point on it has another child.
Thank you in advance. (2 Replies)

Dear all,
I typed in init 1 on my redhat box as root and according to wikipedia (http://en.wikipedia.org/wiki/Runlevel):
1 Single-User Mode Does not configure network interfaces, start daemons, or allow non-root logins
So now I can't connect back to it. How do I change the init back to 3?... (8 Replies)
What is the difference between 'init s' and 'init 1'.
I know that both will work to change the current run level to single user mode.
Is there any difference in those two commands? (5 Replies)

vx_emerg_start
vx_emerg_start(1M)vx_emerg_start(1M)NAME
vx_emerg_start - start Veritas Volume Manager from recovery media
SYNOPSIS
vx_emerg_start [-m] [-r root_daname] hostname
DESCRIPTION
The vx_emerg_start utility can be used to start Veritas Volume Manager (VxVM) when a system is booted from alternate media, or when a sys-
tem has been booted into Maintenance Mode Boot (MMB) mode. This allows a rootable VxVM configuration to be repaired in the event of a cat-
astrophic failure.
vx_emerg_start verifies that the /etc/vx/volboot file exists, and checks the command-line arguments against the contents of this file.
OPTIONS -m Mounts the root file system contained on the rootvol volume after VxVM has been started. Prior to being mounted, the rootvol volume
is started and fsck is run on the root file system.
-r root_daname
Specifies the disk access name of one of the members of the root disk group that is to be imported. This option can be used to spec-
ify the appropriate root disk group when multiple generations of the same root disk group exist on the system under repair. If this
option is not specified, the desired root disk group may not be imported if multiple disk groups with the same name exist on the sys-
tem, and if one of these disk groups has a more recent timestamp.
ARGUMENTS
hostname
Specifies the system name (nodename) of the host system being repaired. This name is used to allow the desired root disk group to be
imported. It must match the name of the system being repaired, as it is unlikely to be recorded on the recovery media from which you
booted the system.
NOTES
HP-UX Maintenance Mode Boot (MMB) is intended for recovery from catastrophic failures that have prevented the target machine from booting.
If a VxVM root volume is mirrored, only one mirror is active when the system is in MMB mode. Any writes that are made to the root file sys-
tem in this mode can corrupt this file system when both mirrors are subsequently configured.
The vx_emerg_start script allows VxVM to be started while a system is in MMB mode, and marks the non-boot mirror plexes as stale. This
prevents corruption of the root volume or file system by forcing a subsequent recovery from the boot mirror to the non-boot mirrors to take
place.
USAGE
After VxVM has been started, various recovery options can be performed depending on the nature of the problem. It is recommended that you
use the vxprint command to determine the state of the configuration.
One common problem is when all the plexes of the root disk are stale as shown in the following sample output from vxprint:
v rootvol root DISABLED 393216 - ACTIVE -
pl rootvol-01 rootvol DISABLED 393216 - STALE -
sd rootdisk01-02 rootvol-01 ENABLED 393216 0 - -
pl rootvol-02 rootvol DISABLED 393216 - STALE -
pl rootvol-02 rootvol DISABLED 393216 - STALE -
sd rootdisk02-02 rootvol-02 ENABLED 393216 0 - -
In this case, the volume can usually be repaired by using the vxvol command as shown here:
vxvol -g 4.1ROOT -f start rootvol
If the volume is mirrored, it is put in read-write-back recovery mode. As the command is run in the foreground, it does not exit until the
recovery is complete. It is then recommended that you run fsck on the root file system, and mount it, before attempting to reboot the sys-
tem:
fsck -F vxfs -o full /dev/vx/rdsk/4.1ROOT/rootvol
mkdir /tmp_mnt
mount -F vxfs /dev/vx/dsk/4.1ROOT/rootvol /tmp_mnt
