Hello,
I've done nimadm alternate disk AIX migration from 5.2 to 5.3 TL8. All went fine, new system rebooted fine but I noticed some fileset inconsistency.

I think that because in AIX 5.2 there were SDD drivers for AIX 5.2 installed and migration process left in ODM "devices.common.IBM.mpio.rte" 5.2.0.x entries as the SDD filesets for AIX 5.2 required them. Now, after I successfully uninstalled the SDD drivers I don't know how to rid of "devices.common.IBM.mpio.rte" for AIX 5.2 entries (the commited ones I think as the onse for AIX 5.3 are only APPLIED)...

1. lppchk -v

lppchk: The following filesets need to be installed or corrected to bring
the system to a consistent state:

bos.rte v=5, r<3 (not installed; requisite fileset)
devices.common.IBM.mpio.rte 5.2.0.0 (not installed; requisite fileset)
devices.common.IBM.mpio.rte 5.2.0.112 (usr: not installed, root: APPLIED)

1. oslevel -s

5300-08-04-0844

1. lslpp -L devices.common.IBM.mpio.rte

Fileset Level State Type Description (Uninstaller)

---

lslpp: 0504-132 Fileset devices.common.IBM.mpio.rte not installed.

1. lslpp -l devices.common.IBM.mpio.rte

Fileset Level State Description

---

Path: /usr/lib/objrepos
devices.common.IBM.mpio.rte
5.3.8.4 APPLIED MPIO Disk Path Control Module

Path: /etc/objrepos
devices.common.IBM.mpio.rte
5.3.8.4 APPLIED MPIO Disk Path Control Module

????

1. lslpp -L devices.sdd.52.rte

Fileset Level State Type Description (Uninstaller)

---

devices.sdd.52.rte 1.6.0.2 C F IBM Subsystem Device Driver
for AIX V52

1. How to fix this post-migration bug?
2. Why migration went fine and there were no complains that these filesets should be uninstalled before migration is started?

1. lppchk -v -m3 2>&1 | grep -c requires

416

1. lppchk -v -m3 2>&1 | sed -n '/requires/{n;p;}'|sort -u

devices.common.IBM.mpio.rte 5.2.0.0

1. lppchk -v -m3 2>&1 | sed -n '/requires/{n;p;}'|wc

416 832 15808
Example output from 'lppchk -v -m3' :

Fileset bos.adt.syscalls 5.3.8.1 requires:
devices.common.IBM.mpio.rte 5.2.0.0

Fileset bos.clvm.enh 5.3.8.2 requires:
devices.common.IBM.mpio.rte 5.2.0.0

Fileset bos.diag.com 5.3.0.40 requires:
devices.common.IBM.mpio.rte 5.2.0.0
What is the IBM's solution to fix it properly? This is the only problem I have after the migration, system works fine...
thx in advance,
K.

Can't offer a method for tidying this up but I believe the SDD readme clearly indicates you need to remove SDD before migrating from 5.2 for 5.3.

thanks but it is not enough to belive. the same I could say that AIX should complains that software XX on level YY is not supported on newer AIX and migration should fail = not be possible to startup in that case to avoid AIX inconsistency.

anyhow, I have found not supported solution (gave by IBM) which helped to fix the problem...

SDD Drivers aren't a core part of AIX. If I had installed HP disk drivers I would read the documentation on how to migrate AIX with them installed, and the same goes for SDD. There's plenty of vital information in the SDD documentation that's never going to be referenced in the AIX documentation.

You're free to ignore the documentation, but then you have to deal with it failing.
