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.

NAME

       iptables-restore -- Restore IP Tables

       ip6tables-restore -- Restore IPv6 Tables

SYNOPSIS

       iptables-restore [-chntv] [-M modprobe] [-T name] [file]

       ip6tables-restore [-chntv] [-M modprobe] [-T name] [file]

DESCRIPTION

       iptables-restore  and ip6tables-restore are used to restore IP and IPv6 Tables from data specified on STDIN or in file. Use I/O redirection
       provided by your shell to read from a file or specify file as an argument.

       -c, --counters
	      restore the values of all packet and byte counters

       -h, --help
	      Print a short option summary.

       -n, --noflush
	      don't flush the previous contents of the table. If not specified, both commands flush (delete) all previous contents of the  respec-
	      tive table.

       -t, --test
	      Only parse and construct the ruleset, but do not commit it.

       -v, --verbose
	      Print additional debug info during ruleset processing.

       -M, --modprobe modprobe_program
	      Specify  the path to the modprobe program. By default, iptables-restore will inspect /proc/sys/kernel/modprobe to determine the exe-
	      cutable's path.

       -T, --table name
	      Restore only the named table even if the input stream contains other ones.
