I have used the Alternate Disk Installation method once for a server I
wanted to upgrade from 5.1 to 5.3 and it worked fine. The only issue I
had was that I did not have the bos.alt_disk_install.rte installed on
the server and had to get those filesets from my original media on the
5.1 system.

I have not used it extensively so cannot give commands off the top of
my head. I would recommend that you look at the cloning option and
install AIX 5.1 mksysb on the "unused" disk, then migrate it to AIX
5.3, and finally reboot the system from the alternate disk and see if
it worked okay.

This is the documentation for the command:

OK thanks

You'll also need a install repository, or NIM server setup first. You
can't just feed in the media.

We do it all the time for AIX 5.3 (cloning + upgrade), here are
steps.

0. Ensure rootvg is not mirrored
1. Check all the logical volume (LV) names are less than 12
characters, otherwise alt_disk_install process will fail, as Operating
System does not allow LV name to
exceed 15 characters. ALT_DISK_INSTALL process prefixes 4 characters
i.e. “alt_” to the existing LV names during the process.
2. Check all filesets are committed.
3. Here is a command to exec:

“alt_disk_install -C -D -V -b update_all -I -acgX -l <Update Filesets
Dir> -P all <new__hdisk> > </tmp/stdout.file> 2> </tmp/stderr.file>

Check the stderr.file for any errors, typically for "savebase" routine
execution. As I have noticed, in case of AIX 5.3 ML3 and above, if
"bos.rte.install" is lower than “5.3.0.54” and/or
“bos.alt_disk_install.rte" is lower than “5.3.0.51”, savebase errors
out. The process may complete, but you would not be able to boot the
box with new disk.

GoodLuck !!!
