I just installed an update to AIX 1.2 on a PS/2 and seem to have lost well over 10 megabytes of precious disk space in the process. Seems that there are some big files in /usr/lpp.save. Just how necessary is it to keep these files around, especially if I don't (or can't) uninstall anything? Incidentally, why doesn't uninst work like the manual says it's supposed to? If I can get rid of some of these files, which ones can I dump safely without jeapardizing future installp's and updatep's? Are there other obscure files that I should target for removal? Would appreciate any help on this as I am running very low on disk space. Antonio Querubin tony@uhcmtg.phys.hawaii.edu

This script will allow you to move the 'lpp.save' files to a backup device, and recover some of your disk space. You will probably only need to keep some of these files around after you do an updatep that you may later want to uncommit/reject. These files allow updatep to restore your system to the way it was before you applied the PTF. You can still remove these files after the update (using 'cleanup'), just make sure you save the backup tape so you can put them back later. One of the reasons uninst doesn't work is because of some cross-lpp dependencies. There are a few lpps that install the same files, so if you uninstall one of the lpps, you will break the others by removing these multiply installed files. /dwight -- Dwight Tovey dwight@locus.com The views I express are entirely my own and do not in any way represent those of Locus Computing.

If you're asking me (one who is running 1.2.1 in 140 *very precious* megabytes of disk space) anytime I do an updatep, I cd /usr/lpp.save as root and /bin/rm -f [0-9]*/* to reclaim space. I just take the "there's no going back" approach. Rich -- Richard Pettit Locus Computing Corp. richp@locus.com "Opinions expressed herein are of the author, not LCC."

Suppose I follow this, what happens when I have to do a second updatep on an LPP? Will updatep require the same information that uninst requires? With the way AIX handles LPP installs and updates, you'd think that it's all a plot to get you to buy a bigger disk drive! An incidental question: Are the man files available in nroff format? Seems like you could gain a little bit of space back by getting rid of the formatted versions of the man files. Antonio Querubin tony@uhcmtg.phys.hawaii.edu

Will updatep require the same >information that uninst requires? Nope. Updatep will just use the /usr/lpp.save/pointer file to figure out where to put the next backup. The files I *would not* delete are /etc/lpp/ghf and /usr/lpp.save/ercv/lpp.ghf. >With the way AIX handles LPP installs and updates, you'd think that it's all >a plot to get you to buy a bigger disk drive!

There are kept in orignal source form in "storybook" or "picturebook" or "some-stupidbook" format. The same as delivered. As an aside, 1.2.1 takes up less space than 1.2.0. I went from 1.1 to 1.2.1 because I felt it was up to the task of the pounding I can give an OS. So far, no major complaints. And Ahhh, NFS, rpc, yp.

No, PS/2 and 370 AIX man files are not available in nroff format. The source for the man pages (and hardcopy) is in IBM Bookmaster format. -- -Steve A.
