SSH Host keys and AIX 7.1 Migration.
Recent releases of AIX installation media
(for 7.1 and 6.1) now contain the OpenSSH base installation filesets. This is
very handy; we no longer need to download or locate the software from other
sources. One thing to consider is what this means
for future AIX migrations. If you are migrating a system (that already
has a version of SSH installed) to AIX 7.1 then you may notice that the first
time you attempt to connect to the server (after the 7.1 migration) the
following ssh message appears: root@nim1

Check your WPAR filesets
Got an issue with mkwpar? Have you checked your WPAR filesets? If you attempt to
create a rootvg WPAR with a VSCSI disk, on a system running AIX 6.1 TL6 and you
encounter the following error: #

Managing users with dsh and chpasswd - (plus info on DSM and dping).
Starting with AIX 7.1, CSM is no
longer supported or available. It has been replaced by Distributed Systems
Managment (DSM). Section 5.2 of the IBM AIX 7.1 Differences Guide Redbook provides
details of the new DSM capabilities.
Fortunately DSM still provides access
to the dsh command. I’ve written about how I’ve used this utility
in the past . The new dsh command (and other tools) are
provided in the new DSM filesets named dsm.core and dsm.dsh . root@nim# lslpp -L dsm*
