Operating Systems AIX 2 default gateways Post 302299393 by zaxxon on Friday 20th of March 2009 02:55:10 AM

We have that kind of phenomenom sometimes too - and as zxmaus says we also think it might be something from our NIM server after an installation of an LPAR.
Though we always had entries in the ODM like shockneck noted.

If you are absolutely sure that there is no entry of that wrong additional default gateway in the ODM, you can try to write a new boot image with
Code:
bosboot -ad /dev/ipldevice
# or
savebase

and check if it is still there after a reboot.

If so, you also might want to check if there is a line in any of your scripts in /etc like rc.tcpip or rc.net that have a line for adding that default GW, just to make sure there isn't:
Code:
find /etc -type f -exec grep -lE "route add|chdev|mktcpip" {} \;

It might list some relevant looking files which might be worth to check.

reboot(8)						      System Manager's Manual							 reboot(8)

Name
       reboot - automatic reboot procedures

Syntax
       /etc/reboot [ -n ] [ -q ]

Description
       The  ULTRIX  system is booted by loading a kernel image, usually into memory at location zero and transferring to zero.	Because the system
       is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.

       When the reboot of a running system is desired, is normally used.  If there are no users, can be used.  The command causes the disks to	be
       synced,	and  then  a multiuser reboot is initiated.  The system is booted and an automatic disk check is performed.  If the procedure suc-
       ceeds, the system is then brought up for the users.

       The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system.  A consistency check
       of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.

Options
       -n   Prevents the disks from being synced.

       -q   Reboots quickly and ungracefully, without shutting down running processes first.

Files
       System code
