Operating Systems AIX Lose IP after TL Update
# 8  
Old 08-13-2013
I do not believe the activation of the IP stack should be dependent on any application. That said, I did have issues myself, and it came down to things I had done "in innocence", i.e. user error in changes to /etc/inittab and/or /etc/rc.d/* scripts.

In my case I did always get an IP address, just lacked some daemons such as ssh.

Besides rebooting several times to try and observe what was going wrong I also used the output of the command alog -o -t console and alog -o -t boot to read messages from programs to find that missing depenadancy.

Unfortunately, for you, I do not remember the specifics - this was too long ago. But I do recommend checking your alog outputs for hints about what is going on, error messages, etc..

mkdev -l en0; mkdev -l inet0 will do what startup should have done (assuming single interface en0. If more interfaces do them all, then inet0.

update_dyld_shared_cache(1)				    BSD General Commands Manual 			       update_dyld_shared_cache(1)

update_dyld_shared_cache -- Updates dyld's shared cache SYNOPSIS
update_dyld_shared_cache [-root directory] [-overlay directory] [-arch arch] [-force] [-debug] [-universal_boot] DESCRIPTION
update_dyld_shared_cache ensures that dyld's shared cache is up-to-date. This tool is normally only run by Apple's Installer and Software Update, as they are the only official ways for OS dylibs to be updated. But if for some reason you used another mechanism to alter an OS dylib, you should manually run update_dyld_shared_cache. Note that the new cache does not take effect until the OS is rebooted. The dyld shared cache is mapped by dyld into a process at launch time. Later, when loading any mach-o image, dyld will first check if is in the share cache, and if it is will use that pre-bound version instead of opening, mapping, and binding the original file. This results in significant performance improvements to launch time. update_dyld_shared_cache scans the directory /System/Library/Receipts/ for .bom files which list all files installed. From that info it cre- ates the set of OS dylibs to build into the dyld cache. update_dyld_shared_cache builds a separate cache file for each architecture. The cache files and a readable text map of the cached are gen- erated to /var/db/dyld. You must be root to run this tool. The options are as follows: -root directory This option specifies the root of an OS installation for which dyld's shared cache should be updated. This is used by the In- staller to update the dyld shared cache in a partition other than the one you into which you are currently booted. The cache files are created in the var/db/dyld directory of the specified directory. Note: if you are manually doing this, be sure to run the update_dyld_shared_cache tool that is in the partition being updated. This assures the cache format created will match that expected when booting off that partition. -overlay directory This option specifies the root of a sparse directory tree. When building the dyld shared cache, any corresponding mach-o files in the sparse directory will override those in the boot partition. This is used by Software Update to build a dyld shared cache for the update that is about to be installed. The cache files are created in the var/db/dyld directory of the specified direc- tory. -arch arch By default update_dyld_shared_cache generates cache files for all architecture that the current machine can execute. You can override this behavior by specifying one or more -arch options and list exactly which architectures should have their shared caches updated. -force This option will cause update_dyld_shared_cache to regenerated the shared cache files even if they appear to be already up-to- date. -debug This option prints out additional information about the work being done. -universal_boot This option builds caches for all machines.
