lppchk -v shows problems with a fileset and you don't want to remove it:

devices.common.IBM.iscsi.rte    (not installed; requisite fileset)

1. save ODM
   tar -cvf /tmp/odm.etc.tar /etc/objrepos
   tar -cvf /tmp/odm.usr.lib.tar /usr/lib/objrepos

2. check lpp_id
   odmget -q name=devices.common.IBM.iscsi.rte lpp
   output will show lpp_id:
    lpp_id = 355

3. delete from ODM
   odmdelete -q name=devices.common.IBM.iscsi.rte -o lpp
   odmdelete -q lpp_name=devices.common.IBM.iscsi.rte -o product
   odmdelete -q lpp_id="355" -o history
   odmdelete -q lpp_id="355" -o inventory

4. reinstall base fileset with force flag (then update)
   installp -aF -d /home/bb/bb1 all



  1. Hi,

    whether .toc (inutoc) is mandatory for all kind of fileset installation. without .toc whether the installation of filesets will not happen ?

    1. Yes, without .toc file (table of conntent) AIX will not recognize installable filesets.

    2. This is not the case with AIX 6.1 and 7.1. If you have write access to the directory containing the filesets, SMIT will create the .toc file if it is missing.

  2. I have a strange problem, friends.
    I am unable to delete the AIX command history on a server that runs AIX 7.1 (oslevel -s => 7100-01-04-1216)
    did the usual > /.sh_history & and echo " " > /.sh_history, to zero out the contents, but it didn't help.
    pls help.


    1. Did you check the content of the file .sh_history after delete? (If it is cleared it should not show you command history)

    2. Yes I did.
      I did a cat /.sh_history and it did show me only the "cat /.sh_history" inside it.
      also did an ls -la /.sh_history and the size was just a few bytes. Saw it increase in size, as I kept typing more commands, but a #history -400 or an Esc+K was able to fetch all the 400 commands when I had just typed 3 or 4 commands since the time I last cleared the contents of the history file.
      This is very strange.
      Any help will be much appreciated.

    3. After logout /login was the same?

    4. During your active session, .sh_history will be an open file. As the previous poster said, you need to logout and log back in to see that your command history has been deleted.

  3. yes. was the same, after a logout and a re-login.
    Was also the same, after a # shutdown -Fr.

    1. I think i have found it :) The problem is with the "/".
      You wrote "> /.sh_history", but I guess your home dir is not "/" (probably it is /root).
      You should try to clear the .sh_history file in your home dir (for example: "> /root/.sh_history")

    2. Your home will be ~root and will also be stored in $HOME. Unless you are doing a sudo or a su (without the "-"), the only .sh_history you will need to deal with will be the on in ~root.
      The old biggies (AIX, Solaris, HP-UX, Digital UNIX, etc) put root's home in /. I had not seen it put in /root until LINUX.
      If you are going to be an SA, you need to get used to knowing where you are and what you are doing as root. Otherwise, you might destroy your system.

  4. Hello.
    AIX does not create a /root as the root user's home directory. It's always a /.
    I've always been clearing histories, for more than 6 years now. This symptom is clearing getting me frustrated. pls help.

    1. Hello, if you use /root as a home dir, then you can keep / filesystem clean, so your files will not be mixed up with other system files. In our environment we use /root for root home dir and I know many other sysadmin doing the same way.

      I think you should run a find command on your full system to search for sh_history files, probably you will find another one, where your commands are logged.

    2. If you have a multi-user system and remove all of the .sh_history files that a find as root will show, you will have some irritated users.

    3. you shouldn't delete history

  5. Your website is amazing. Preparing for the AIX 7 certification. What version of AIX are you using in your environment?

    1. I asking because I see that the AIX 7.1 Differences Guide is 400+ pages, meaning there is a lot of new stuff when comparing it to 6.x or 5.x

    2. We are still using mostly 6.1 and only a few 7.1. I'm not the decision maker at our company about AIX levels, and it depends on the applications as well, if they can run on 7.1 or not.

  6. Hi,

    I am trying to update my VIO server from to then to So I ran updateio command and which completed successfully and when i do ioslevel can it shows but when I ran lppchk -v It's showing some inconsistent filesets. I checked the log and it shows the following error, even the .toc file is inplace.

    0503-466 installp: The build date requisite check failed for fileset bos.rte.security.
    Installed fileset build date is 1015. Selected fileset does not have a build date, but one is required.
    0503-466 installp: The build date requisite check failed for fileset bos.rte.security.
    Installed fileset build date is 1043. Selected fileset does not have a build date, but one is required.
    installp: Installation failed due to BUILDDATE requisite failure.

    Can you please help.


    1. Hi,

      2 things came to my mind:

      1. remove .toc file and create a new one with command inutoc (as root) in the install directory. Then try again updateios.

      2. Remove problematic fileset, check oslevel and install missing requirements step by step

      If ioslevel output is correct, it means all filesets for correct VIO server functionality are installed, but I would also try to fix this missing fileset problem. There is a known issue with (http://www-01.ibm.com/support/docview.wss?uid=isg400000800). If you check at the and of this link, it will list some filesets which requisites are failed to install, but it can be ignored. So what we do, we don't bother with missing filesets at and if ioslevel is correct, we update VIO server to and only after that we correct missing fileset problems. (This is our approach, but I don't remember we had this specific issue what you had.)

      (A good backup scenario is also needed before trying to correct these things.)

      Hope this helps,

    2. You can force the re-install. We ran into the same issue and forced the re-install.
      installp -F -ac -d /source_of_filesets/installp/ppc bos.rte.security

  7. Thanks again for your reply!
    Below are the filsets I see after running lppchk -v. Not sure how to make these filesets consistent/reinstall. BTW I tried to run 2213 updates form new source and created new .toc.

    # lppchk -v
    bos.rte.security (usr: COMMITTED, root: not installed)
    bos.rte.shell (not installed; requisite fileset)
    bos.sysmgt.serv_aid (not installed; requisite fileset)
    bos.sysmgt.trace (not installed; requisite fileset)
    bos.sysmgt.trace (not installed; requisite fileset)

    # lslpp -L | grep bos.rte.security
    bos.rte.security ? F Base Security Function

    # lslpp -L | grep bos.sysmgt
    bos.sysmgt.loginlic C F License Management
    bos.sysmgt.nim.client C F Network Install Manager -
    bos.sysmgt.quota C F Filesystem Quota Commands
    bos.sysmgt.serv_aid C F Software Error Logging and
    bos.sysmgt.smit C F System Management Interface
    bos.sysmgt.sysbr C F System Backup and BOS Install
    bos.sysmgt.trace C F Software Trace Service Aids

    1. You can get more details by running "lppchk -v -m3". I would probably try to re-install them 1 by 1. First remove problematic fileset then install it, and do it for the others as well. If removing does not work you can clean up fileset from the ODM (see "FIXING FILESETS in ODM", a little above), but if you make something wrong you can mess up the whole ODM.

      Usually, if I am not sure what to do, I am opening an IBM call, I would suggest this to you as well...

  8. Hi admin,
    Thanks for the excellent document it is very helpful, need to know we can perform multibos migration?
    Thanks & Regards

    1. Hi, info about multibos can be found here: http://aix4admins.blogspot.hu/2011/09/by-default-bos-filesystems-in-rootvg.html

  9. Here i can find all box packages? and what is bos file? anyone please help

  10. I upgraded the tl 05 to tl06.but it is showing old version.give me the prerequisites all

  11. its urgent can u tell me how to copy a specific fileset from CD into a directory??

  12. how can I check of a installed ifix with instfix command?

  13. Hi...Gyz who one interested for online Aix server remote for training purpose.so please contact me (mr.ravi751@gmail.com)and get more details.

  14. does it have to be a mountpoint to stage the patch? or any path will work?

  15. Can you tell me the command to install packages without dependencies in AIX 6/7

  16. Can I revert back to previous version of TL by rejecting the Apllied filesets of newer version ?

    1. Hi, rejecting the applied filesets works for few filesets, but in a TL there are so many filesets, so it is not recommended to do that.
