I was cloning a system from a NIM mksysb at AIX 5.3 ML 7 and chose the option to ‘reduce the filesystem’ sizes. This seemed to work fine, but it reduced the size of /tmp to a point that it could not create a boot image when it got to that part of the install. No problem, I just went to the maintenance shell, removed some useless files, and reran the command. The bosboot worked fine. When I exited from the maintenance shell, the install continued and finished successfully. Unless you get failures during the actual restore command, you can often figure out what went wrong and just continue. Sysback operates the same way. It appears to have retried the command, because when I continued on, it looks like it tried the mksysb again:

After that everything works fine.
Hi, I have some trouble with my mksysb …
In fact, I have an old image.data file with fs too small, and during restore of the mksysb of course an “No space left” error occurs. But when my system gives me the options
1. Continue
2. Perform Maint …
and I press 2 and get the dash prompt, any command I issue, I have no return whatsoever. Pressing return again, I get the dash back.
And some time later, the restore wakes up and tells me to put the next CD into the CD drive.
Looks like Maintenance shell just isn’t working.
What am I missing, any bosinst.data parameter?
Thanks a lot and have a nice day, Igor
PS: Yes, we are still on some AIX 4.3.3-11 machines in the year 2011 😉
