Booting a system interactively is useful if you need to specify an alternate kernel or the /etc/system file during the boot process because the original file is damaged or the system will not boot. Use the following procedure to boot a system interactively.
The following procedure describes how to specify an alternate /etc/system file during an interactive boot of a system that has only one boot environment. Alternatively, you can boot an alternative boot environment.
# cp /etc/system /etc/system.bak # cp /boot/solaris/filelist.ramdisk /boot/solaris/filelist.ramdisk.orig # echo "etc/system.bak" >> /boot/solaris/filelist.ramdisk
# reboot -p
Name of system file [etc/system]: /etc/system.bak
Pressing Return without providing any information accepts the system defaults.
# reboot
In the following example, the system defaults (shown in square brackets []) are accepted.
# init 0 # svc.startd: The system is coming down. Please wait. svc.startd: 121 system services are now being stopped. Apr 22 00:34:25 system-28 syslogd: going down on signal 15 svc.startd: Killing user processes. umount: /home busy Apr 22 06:34:37 The system is down.
