A kind soul sent me the AIX dianostics disk set to try to break into the powerserver 320h, and I am having mixed results. With the switch in service mode, I was able to make the machine boot off the floppies; eventually it reaches a menu: AIX 3.2 INSTALLATION AND MAINTENANCE Select the number of the task that you want to perform >>>> 1 Install AIX 2 Install a system that was created with the SMIT "Backup the System" function or the "mksysb" command 3 Install this system for use with a "/usr" server. 4 Install a limited function maintenance shell. Type the number of your selection, then press "Enter": 4 Type 'exit' to return to the main menu.

Ok, so I make /usr1, copy all the stuff in the ramdisk /usr to /usr1 (also in ramdisk) and run getrootfs again. Still no luck mounting /usr . So, using the tools that I copied into /usr1 I mount /dev/hd4 in /mymnt/hd4 and /dev/hd2 in /mymnt/hd2 ; further investigation reveals that there indeed exist directories /mymnt/hd2/bin, /mymnt/hd2/lib, /mymnt/hd4/etc and so on; I seem to have mounted / and /usr from the HD correctly.

Continuing tale of the Powerserver 320H

I think 3.2 uses shared libraries, and vi probably needs something in a library that's not mounted (or not in the right place) when running the limited maintenance shell. I'm surprised ls doesn't work, though. The shell should support ls, dd, backup, restore, chown, mkfs, mknod, mount, and things like that. And of course, our editor of choice: ed. > #cat /etc/mnttab Have a look in /etc/filesystems and see what it thinks it should mount for "mount all". I think AIX actually deletes /etc/mnttab as part of the normal startup, and does a "touch /etc/mnttab" to leave an empty file. > #getrootfs > usage: /usr/sbin/getrootfs [-f] diskname > -f disregard status of hd5 > Available disks: location: > hdisk0 00-01-00-00 > > #getrootfs -f hdisk0 > Importing Volume Group... > rootvg > /dev/rhd4 (/): ** Unmounted cleanly - Check supressed > /dev/rhd2 (/usr): ** Unmounted cleanly - Check supressed > /usr/sbin/getrootfs: mount: not found > checking all mounts and the existance of df > /usr/sbin/getrootfs: mount: not found > /usr is not mounted > > #ls > ls: not found > #mount > mount: not found > #umount > Usage: umount [-sf] {-a|-n Node|-t Type|all|allr|Device|File|directory|File > System} > # > > Further investigation revealed that if I "umount /usr", then there is > some mount executable in the ram disk.

Possibly in /etc/security/passwd, /etc/security/group, and so on. Don't believe AIX is UNIX. It's not. > # passwd > cannot execute Probably the executable isn't in your PATH. If you have the filesystems mounted (BTW, why "mymnt" not just "mnt"? That's what mnt is for) you can add the relevant directories PATH=/mymnt/hd2/bin:$PATH but it might be better (if you just have two partitions on the hard drive) to mount hd2 directly on /mnt, and then mount hd4 on /mnt/usr. At least then things will be in the correct places relative to each other. There isn't a directory called "/root", is there? You could try the "users" command, though I expect it only works on a normal system (ie not from the maintenacne shell, which is sort of a mini system, like the miniroot or standalone shell in IRIX and Solaris). If you can edit /etc/passwd with ed, you can probably remove the password field >from root's entry, leaving a null field (no password). -- Pete Peter Turnbull Network Manager University of York

It looked like a good idea because the outside track is inside the scan area. Unfortunately after I got the scanner apart, I discovered that the xenon(or whatever) tube not only does not light all the way to it's end, but it also has an electrode at the end. It just sticks out too far and has to extend past the edge of the scan area in order to illuminate the whole area. Oh well.

I sold them years ago at a computer store in NJ, and had one for a few years shortly thereafter. Lots of fun! SVR2 UNIX on a 10MB disk with 512KB of RAM! :-) -Dave -- Dave McGuire St. Petersburg, FL
