Greetings everyone;

I have recently started to work on bringing up an old 7012-320H that I was given a few years ago. I have pinpointed part of the boot problems to the fact that the machine does not have an /etc/mount binary; the installed AIX version is 3.1 . Does anybody have by any chance an /etc/mount binary that you could share?

Regards,

Carlos Murillo.

are you installing from a graphics display or from a serial terminal?

From a serial console; this machine is headless.

Do you have the original install media?

No, and that's the problem. Originally it would not boot (it would post a 553 led message and stall), but I was able to get to the maintenance console using BOSboot diskettes that I downloaded from the net. The problem is, these diskettes are for AIX 3.2, not 3.1 like in the hard drive. I was careful not to run the 3.2 maintenance getrootfs script, which is documented to wreak havoc in a 3.1 installation, but still managed to mount the 3.1 filesystems in the 3.2 maintenance shell, and that's how I figured that the /etc/mount binary is missing. I also verified that the 3.1 binaries do not run under the 3.2 maintenance console, nor do the 3.2 maintenance console binaries run under the AIX 3.1 system. I was able to partially boot from thehard drive once I fixed /etc/security/passwd and /etc/inittab in the hard drive, except that only the /dev/hd4 (root) filesystem mounts; all the
other ones (/usr, /tmp, /u) don't mount because of the lack of /etc/mount .

I just need the /etc/mount binary to make this work, I think.

I've got a 320 over here i've been meaning to restore. it had drives in it, but when it arrived, the drives were toast. what a pain in the ass machine this is -- in addition to it's desire for a speaker keyboard, it takes some nonsense cable adapter to create a serial port. I finally assembled all of the parts I thought I would need, only to find out the holes in the hard disk sled, they really only align with the old IBM drives.

I'm almost sure they dumped my IBM 2GB F/W drive stock when we moved warehouses, so I'm more than slightly annoyed.

I don't know what to tell you about your mount malfunction. I started my AIX journey about six months ago with a -39H, a machine much more forgiving than the -320 -- well, only as far as interfaces go, I did blow the fucker up once already)

I really only have less than basic knowledge of 4.3.3 and 5.1. Maybe I know a little bit more, but nothing of any kind of teachable degree. There doesn't seem to be many folks chatty on the forum, and I didn't want to leaveyou without a response.

but, are you in love with 3.1? the -320 should be able to run 4.3.3 I think.. attach a scsi cdrom to an open box, boot from the cd and lay a new AIX down..

I'll be around if you want to bounce ideas or whatever. OH, and if you do find 3.xx media, let me know !!

Thanks,
Lorenzo

Thanks, Lorenzo. I have actually made good progress: I inspected the image of the hard drive, hoping to find an image of the deleted mount command.I did find it and scraped the binary off the hard drive image, and to my surprise, some of the strings in it were related to errors while _unmounting_ . This made me think that perhaps the mount binary was the same as the /etc/unmount binary, which was present, and on execution it changes its behavior according to its name. So I copied /etc/unmount to /etc/mount and voila' ! it worked! Now I am thinking about backing up what I have and make BOSboot diskettes from the current system. Afterwards, I need to understand /etc/migratepv to see if I can move this system to a larger hard drive.

The system comes with cc, c89, xlc (all dinosaurs) and cobol. It also has Qcalc, a text-based spreadsheet! I ran a few benchmarks (hanoi, whetstone, flops) and was surprised that it was somewhat faster than I expected; the flops benchmark tops 12 MFlops, for example.

I had experience from userland with AIX back in the 90's in the context of an SP2 Blue Gene cluster when I was a grad student, but it is only now (couple of weeks in my scarce spare time) that I have been learning the adminside, so it is all new to me. Very BSD-ish and weird.

I also thought about installing 4.3.3 (I have the media), but I wonder if a320H with just 32MB RAM will be too sluggish under 4.3.3 ...

For the time being, I used the included /usr/bin/xmodem command to transfersome tarred files and got gkermit compiled and running to be able to better transfer source tar files and start building a better toolchain. It's been a long while since I transferred stuff using kermit at 9600 baud.

if you can get it networked, use ftp from a modern machine, that's how i'vebeen moving files to and from the boxes here... great you're making progress !!

Unfortunately, it came without a LAN adapter. And, V3.1 does not have a SLIP or PPP driver, but I've heard that the SunOS 4.1.x SLIP driver implementation can be easily adapted, and I have the sources for that, so at some point in the future I'll give that a try. Imagine, having that machine connected at 115Kbaud....

I'll need to look at how to fix a non-IBM hd to that caddy...

Does this old version of AIX have mksysb?

Keep in mind that RIOS/POWER1 is a superscalar design and with execution
width that other architectures didn't match for quite a while. It's
possible to get 4 instructions per clock (a branch, a condition-register
instruction, a fixed-point instruction, and a floating-point
instruction) which could include a FMA (fused-multiply add) going on
this implementation.

Yes that would be a bad time. AIX 3.2.5 would be best for that config.
Although 4.1 and 4.2 might be ok too but I don't have a lot of
experience with those.
