Please make sure you have the correct gateway address in netconf file. If the new IP address is in a diffent subnet than the original one, you need to update the gateway otherwise when you reboot it might be looking for other servers like NFS, NIS server etc

reboot

REBOOT(2)							System Calls Manual							 REBOOT(2)

NAME

       reboot - reboot system or halt processor

SYNOPSIS

       #include <sys/reboot.h>

       reboot(howto)
       int howto;

DESCRIPTION

       Reboot  reboots	the system, and is invoked automatically in the event of unrecoverable system failures.  Howto is a mask of options passed
       to the bootstrap program.  The system call interface permits only RB_HALT or RB_AUTOBOOT to be passed to  the  reboot  program;	the  other
       flags  are  used  in scripts stored on the console storage media, or used in manual bootstrap procedures.  When none of these options (e.g.
       RB_AUTOBOOT) is given, the system is rebooted from file "vmunix" in the root file system of unit 0 of a disk chosen in a processor specific
       way.  An automatic consistency check of the disks is then normally performed.

       The bits of howto are:

       RB_HALT
	      the processor is simply halted; no reboot takes place.  RB_HALT should be used with caution.

       RB_ASKNAME
	      Interpreted by the bootstrap program itself, causing it to inquire as to what file should be booted.  Normally, the system is booted
	      from the file "xx(0,0)vmunix" without asking.

       RB_SINGLE
	      Normally, the reboot procedure involves an automatic disk consistency check and then multi-user operations.  RB_SINGLE prevents  the
	      consistency  check,  rather  simply  booting  the  system  with a single-user shell on the console.  RB_SINGLE is interpreted by the
	      init(8) program in the newly booted system.  This switch is not available from the system call interface.

       Only the super-user may reboot a machine.

RETURN VALUES

       If successful, this call never returns.	Otherwise, a -1 is returned and an error is returned in the global variable errno.

ERRORS

       [EPERM]	      The caller is not the super-user.

SEE ALSO

       crash(8), halt(8), init(8), reboot(8)

BUGS

       The notion of ``console medium'', among other things, is specific to the VAX.
