Fairly simple question here. I know that in Solaris 10 there is a way to tell a system running solaris 10 to init 0 and then boot disk1 all in the same command line from a SSH window. That way once you hit enter it then performs the init 0 and then does the boot disk1. ... (2 Replies)

reboot
reboot(1M) System Administration Commands reboot(1M)
NAME
reboot - restart the operating system
SYNOPSIS
/usr/sbin/reboot [-dlnq] [boot_arguments]
/usr/sbin/reboot [-f [-e environment]] [-dlnq] [boot_arguments]
DESCRIPTION
The reboot utility restarts the kernel. The kernel is loaded into memory by the PROM monitor, which transfers control to the loaded kernel.
On x86 systems, when the -f flag is specified, the running kernel will load the next kernel into memory, then transfer control to the newly
loaded kernel. This form of reboot is shown in the second synopsis, above.
Although reboot can be run by the super-user at any time, shutdown(1M) is normally used first to warn all users logged in of the impending
loss of service. See shutdown(1M) for details.
The reboot utility performs a sync(1M) operation on the disks, and then a multi-user reboot is initiated. See init(1M) for details. On x86
systems, reboot may also update the boot archive as needed to ensure a successful reboot.
The reboot utility normally logs the reboot to the system log daemon, syslogd(1M), and places a shutdown record in the login accounting
file /var/adm/wtmpx. These actions are inhibited if the -n or -q options are present.
Normally, the system reboots itself at power-up or after crashes.
OPTIONS
The following options are supported:
-d
Force a system crash dump before rebooting. See dumpadm(1M) for information on configuring system crash dumps.
-e
If -f is present, reboot to the specified boot environment.
-f
Fast reboot, bypassing firmware and boot loader. The new kernel will be loaded into memory by the running kernel, and control will be
transferred to the newly loaded kernel. If disk or kernel arguments are specified, they must be specified before other boot arguments.
This option is currently available only on x86 systems.
See EXAMPLES for details.
-l
Suppress sending a message to the system log daemon, syslogd(1M) about who executed reboot.
-n
Avoid calling sync(2) and do not log the reboot to syslogd(1M) or to /var/adm/wtmpx. The kernel still attempts to sync filesystems
prior to reboot, except if the -d option is also present. If -d is used with -n, the kernel does not attempt to sync filesystems.
-q
Quick. Reboot quickly and ungracefully, without shutting down running processes first.
OPERANDS
The following operands are supported:
boot_arguments
An optional boot_arguments specifies arguments to the uadmin(2) function that are passed to the boot program and kernel upon restart.
The form and list of arguments is described in the boot(1M) and kernel(1M) man pages.. If the arguments are specified, whitespace
between them is replaced by single spaces unless the whitespace is quoted for the shell. If the boot_arguments begin with a hyphen,
they must be preceded by the -- delimiter (two hyphens) to denote the end of the reboot argument list.
EXAMPLES
Example 1 Passing the -r and -v Arguments to boot
In the following example, the delimiter -- (two hyphens) must be used to separate the options of reboot from the arguments of boot(1M).
example# reboot -dl -- -rv
Example 2 Rebooting Using a Specific Disk and Kernel
The following example reboots using a specific disk and kernel.
example# reboot disk1 kernel.test/unix
Example 3 Fast Rebooting
The following examples use the f option to perform fast reboots.
The following command reboots to the same kernel.
example# reboot -f
The following command reboots to another UFS root disk.
example# reboot -f -- '/dev/dsk/c1d0s0'
The following command reboots to another ZFS root pool.
example# reboot -f -- 'rpool/ROOT/root2'
The following command reboots to mykernel on the same disk with -k option.
example# reboot -f -- '/platform/i86pc/mykernel/amd64/unix -k'
The following command reboots to mykernel off another root disk mounted on /mnt.
example# reboot -f -- '/mnt/platform/i86pc/mykernel/amd64/unix -k'
The following command reboots to /platform/i86pc/kernel/$ISADIR/unix on another boot environment named second_root.
example# reboot -f -e second_root
The following command reboots to the same kernel with -kv options.
example# reboot -f -- '-kv'

NOTES
The reboot utility does not execute the scripts in /etc/rcnum.d or execute shutdown actions in inittab(4). To ensure a complete shutdown of
system services, use shutdown(1M) or init(1M) to reboot a Solaris system.
