I have a very old hp rp2450 running 11i2 that I had to power off. When turning it back on it hangs with the following message. Would booting into SUM get me any further? I've never used SUM, so I'm asking before I go down that rabbit hole.
Hi All,
There was a background process running on a Solaris 2.8 machine, and appeared to have filled all available disk-space. I done a killall, and upon re-booting found that the file system had filled up, and will not boot as normal as a result. For example, I'm getting

I'm running solaris 2.5.1. My main development server is DEAD, i can't even boot off the cdrom, it powers up, acts like it is starting the boot process but then says cannot find boot device. I've done the search here on this site and saw the other posts, but at the ok prompt it won't even let me... (3 Replies)
Hi,
I have an SGI workstation running on Irix 6.5. A few days ago the system started giving messages that the root directory is full. Even before I could find out how to clean up the root directory, the system crashed and does not boot anymore. Can anyone help me on how I can get the system to... (1 Reply)

Hey all,
What do you think mostly happened in the following situation?
I have a Red Hat 5.5 server. Someone, somehow, managed to get two .nfs000.... type files that totaled over a terabyte in size. I removed them and thought things were back to normal. Then I started getting complains from... (2 Replies)
We have an issue here:
The libc.so.6 file (link) is corrupted and it causes the system unbootable. It even doesn't boot to single user mode. How can we boot the system to fix the library file? Or is there any other solutions for this issue?
Here are some boot messages:... (6 Replies)
Hi All,
I have successfully backup & restore (using tar) one of my Debian Lenny Servers.

Dear all
I have a SPARC solaris 5.10 system. I did something very silly while editing the vfstab file I modified the root (/) filesystem mount point setting to be /dev/dsk/c0t0d0s0 /dev/rdsk/c0t1d0s0 notice the difference.
When I rebooted the system it fails with a service called... (2 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
