Operating Systems Solaris Cannot boot in single-user mode Post 302312354 by sbk1972 on Friday 1st of May 2009 02:43:03 AM

IVe had a similar problem. ITs where the home directory of the root user has been altered and relocated to a drive that is mounted in multiuser mode.

Dont get me wrong, I never configured this rubbish, but I noticed it on a server the other day when I tried to boot -s myself. The previous sa wally had pointed root to /u01/, so single user mode wouldnt work, and went straight to multiuser mode.

Check the root entry in /etc/passwd. Make sure the home directory is / and if the shell has been changed, makes sure its /sbin/sh Ive seen it where ksh has been the choice of shell, but located on a different mount, mounted at multi user mode.

Give that ago.

NAME
re-preinstall - installs the JumpStart software on a system SYNOPSIS
cdrom-mnt-pt/Solaris_XX/Tools/Boot/usr/sbin/install.d/re-preinstall [-m Solaris_boot_dir] [-k platform_name] target-slice DESCRIPTION
re-preinstall installs the JumpStart software (preinstall boot image) on a system, so you can power-on the system and have it automatically install the Solaris software (perform a JumpStart installation on the system). When you turn on a re-preinstalled system, the system looks for the JumpStart software on the system's default boot disk. All new SPARC systems have the JumpStart software already preinstalled. The XX in Solaris_XX is the version number of the Solaris release being used. You can use the re-preinstall command in several ways. The most common way is to run re-preinstall on a system to install the JumpStart software on its own default boot disk. This is useful if you want to restore a system to its original factory conditions. (See the first procedure described in EXAMPLES.) You can also run re-preinstall on a system to install JumpStart software on any attached disk (non-boot disk). After you install the Jump- Start software on a disk, you can move the disk to a different system and perform a JumpStart installation on the different system. (See the second procedure described in EXAMPLES.) re-preinstall creates a standard file system on the specified target-slice (usually slice 0), and re-preinstall makes sure there is enough space on the target-slice for the JumpStart software. If sufficient space is not available, re-preinstall fails with the following message: re-preinstall: target-slice too small xx Megabytes required You can use the format(1M) command to create sufficient space on the target-slice for the JumpStart software. OPTIONS
The following options are supported: -k platform_name Platform name of the system that will use the disk with the JumpStart software. The default is the platform name of the system running re-preinstall. (Use the uname(1) command (-i option) to determine a system's platform name.) -m Solaris_boot_dir Absolute path to the Solaris_XX/Tools/Boot subdirectory of a mounted Solaris CD or a Solaris CD copied to disk that re-preinstall uses to install the JumpStart software. The default is root (/), which is where the Solaris CD is mounted in single-user mode. OPERANDS
The following operands are supported: target-slice Device name of the disk slice where the JumpStart software will be installed (usually slice 0), for example, c0t3d0s0. EXAMPLES
Example 1: Installing the JumpStart Software on a System's Own Default Boot Disk The following procedure installs the JumpStart software on a system's own default boot disk: 1. From the ok prompt, boot the system from the Solaris media CD or DVD in single-user mode: ok boot cdrom -s 2. The following command installs the Jumpstart software on the System default boot disk, c0t0d0s0 on a Solaris 9 system: example# /usr/sbin/install.d/re-preinstall c0t0d0s1 3. Reboot the slice: example# reboot disk:b Example 2: Installing the JumpStart Software on a System's Attached (non-boot) Disk The following procedure installs the JumpStart software on a system's attached (non-boot) disk: 1. Mount the Solaris CD or DVD if vold(1M) is not running or CD or DVD is not mounted. 2. Use the format(1M) command to determine the target-slice where JumpStart will be installed. 3. Use the uname(1) command (-i option) to determine the platform name of the system that will use the re-preinstalled disk 4. Run re-preinstall with the -m Solaris_boot_dir option if the Solaris CD or DVD is not mounted on /cdrom. The following command installs the JumpStart software on the system's attached disk for a system with a Sun4u kernel architecture, and it uses the Solaris CD or DVD mounted with vold(1M) on a Solaris 9 system: example# /cdrom/cdrom/s1/usr/bin/install.d/re-preinstall -m /cdrom/cdrom/s1 -k sun4u c0t2d0s0 EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error has occurred. ATTRIBUTES
