There might be quite a few reasons why a db2iupgrade might complain with DBI1124E, starting from genuine binary issue or, instance been auto started before trying a db2iupgrade or, many times some kind of environment issue related to hard coded path or, bad link etc.
But, there are times when all these environment reasons mentioned above might not be the cause of the problem.
Checking of the above might show all o.k.. But, still might face the same issue.
Complain will look like,
# ./db2iupgrade -u db2inst1 db2inst1
