how many run level in solaris?

Answer Posted / johnny agarwal

In solaris 10 there are 8 run level

init -0 To shut down the operating system so that it is
safe to turn off power to the system
init -s or S To run as a single user with some file systems
mounted and accessible.
init -1 To access all available file systems. User logins
are disabled
init -2 For normal operations. Multiple users can access the
system and all file system. All daemons are running except
for the NFS server daemons
init -3 For normal operations with NFS resources shared.
This is the default run level for the Solaris OS.
init -4 Not configured by default, but available for
customer use
init -5 To shut down the operating system so that it is safe
to turn off power to the system. If possible, automatically
turns off power on systems that support this feature.
init -6 To shut down the system to run level 0, and then
reboot to multiuser level with NFS resources shared (or
whatever level is the default in the inittab file).
