  1. How to backout of Solaris 10 kernel patch - Newbie question

    Dear Sir/Madam,

    I've just applied a kernel patch #127111-10 at our Solaris 10 server
    which runs Veritas Storage Foundation for Oracle with root mirrored
    and encapsulated. The command I used was "# patchadd 127111-10". The
    server has been running that kernel patch for 2 days. Unfortunately,
    we've been asked to back it out for trouble-shooting purposes. How
    does one back out the patch to the previous version of 127111-09?
    Can I just do "# patchrm 127111-10" according to the readme. Is there
    anything we need to be aware of before and after running the
    patchrm ? Down the road, is it ok to reapply the 127111.10 again ?

    Thanks,

    Bill

    Yes, patchrm is the way to uninstall a patch. If you do
    "patchrm 127111-10", you will not neccessarily go to 127111-09.
    Instead, you'll find that you go the last installed version
    before 127111-10 - let's say you have revs 05, 08 and 10 installd.
    If you'd do the patchrm, you'll be at rev 08.

    If you need to go to rev 09, you'll have to patchadd that revision
    afterwards.

    Assuming the -09 revision was on the box before the -10 then you'll
    just need to do a patchm then a reconfig boot (as it's a kernel patch).
