That depends on what you did. As you did not give a proper description on what that was I assume that you did sth. like a smitty update_all. In this case there is a build in parachute in installp that will allow you to return to the previous software levels. To pull the ripcord you did tell the update not to commit but to apply and keep the older packages. This way you could simply reject all packages that are applied but not commited.
Occasionally some packages are commited automatically even if you told installp to apply only. This would be the case if new filesets came with the update packages. However, as such a fileset has not been there before the update operation you could uninstall it.

Now what to do if the software was commited during update? In that case you might try to do a forced overwrite with the previous/older versions. But be warned: this is not supported officially and does not always work. You might end up with a server with inconsistent software levels. I'd not recommend it for servers that are critical for production.

Last resort: recover the server from the backup you did before updating. Depending on the possibilities you have this might be the fastest way to return to the previous oslevel anyway.

Hi All, Is multibos really needed on each sp update on a hacmp config? Is someone using it? I have an up coming update and I don't have time to understand this technology. Does SP update might screw you up and you can't restore properly from it? Thanks for any idea in advance.

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

NAME

       daptup - wrapper script on 'apt-get update'

SYNOPSIS

       daptup [ --pre | --post | --last ] [ -h | --help ] [ --nocolor ]

OPTIONS

       --pre  Do only 'pre' stage: collect info that will be used as 'old'. Usually need to be specified only in apt hooks.

       --post If  appropriate option is enabled in config file, do only 'post' stage: collect 'new' info and output changes. Otherwise do nothing.
	      Usually need to be specified only in apt hooks.

       --last Output changes only. This option is supposed to be specified when you want to see changes made in the last update. Note that list of
	      outdated packages, if daptup is configured to output it, will be rebuilt.

       -h --help
	      prints the help

       --nocolor
	      Disables	color  output, useful for scripts or when output is not terminal. Now works only with --last option, however, you can dis-
	      able color globally in configuration file.

       daptup is a script that runs "apt-get update" inside and outputs list of packages recently entered to repo, list of packages which got  new
       updates, list of changes in 'watched' packages and, optionally, list of outdated packages.

       Starting with 0.8.0 version, daptup uses apt hooks and you don't need to explicitly call it if you use 'apt-get update'.

TROUBLESHOOTING

       If  daptup was interrupted while building the lists, the cached lists can stay in inconsistent state, which is inappropriate if you want to
       use --last option before the new update. There is nothing to do if interrupt was occured  at  the  moment  when	old  lists  were  building
       (besides  running  the  new  update). However, if interrupt was occured when the new lists were building, you can easily redo this stage by
       calling 'daptup --post'.

FILES

       /etc/daptup.conf
	      self-documented configuration file

       /var/spool/daptup/outdated
	      cached file with info about outdated packages
