When trying to update AIX 5.3 to 6.1 using an alt_disk migration, I kept getting this error:

+-----------------------------------------------------------------------------+
Executing nimadm phase 5.
+-----------------------------------------------------------------------------+
Saving system configuration files.
/usr/bin/lslpp: No such file or directory
0505-177 nimadm: An unrecoverable error has occurred during pre-install processing.
Cleaning up alt_disk_migration on the NIM master.
Unmounting client mounts on the NIM master.

I searched around a lot and couldn’t find much of an answer besides one obscure reference to adding more disk space to /, so I did:

# chfs -a size=+1G /
Filesystem size changed to 2621440

..and the problem went away, the alt_disk_upgrade then ran successfully.

The quick way to create a mksysb of an AIX system:

mksysb -i -p -e /path/to/mksysb
