Symptom
=======
The db2iupgrade tool fails with the error (db2iupgrade log):
DBI20164E The db2iupgrade command failed because of a problem
with the DB2 product installation on a host machine in the DB2
cluster.
In the /tmp/db2log/DB2Validation.trc of any of the remote hosts,
there is an error, "Version mismatch", in the step
INSTALLED_DB2_VERSION_REMOTE:

Reason and Prerequisites
==================
Before DB2 10.5 FP4, during a DB2 version upgrade of a DB2
pureScale instance, the db2iupgrade tool only upgraded the local
host and thus had to be run on each of the participating cluster
hosts individually.
In DB2 10.5 FP4, the default behaviour has been changed to use
the "-g" parameter, that upgrades all the members and CFs
(globally) in the DB2 pureScale cluster. During this process,
the db2iupgrade tool checks the validity of the remotely
installed DB2 software. There is a programming error on this
validating process against a special build resulting in the
mentioned failure.
This problem affects all platforms supported for pureScale (AIX
and LinuxAMD64); and it covers both the DB2 9.8 (pureScale) to
10.5 FP4 (pureScale) upgrade and the DB2 10.1 (pureScale) to
10.5 FP4 (pureScale) upgrade.
This problem is planned to be addressed in a future 10.5 Fix
Pack. |
****************************************************************
* USERS AFFECTED: *
* It only affects special build made on top of DB2 10.5 FP4 *
* with the command db2iupgrade against a pureScale enabled *
* system during a version upgrade. *
****************************************************************
* PROBLEM DESCRIPTION: *
* In the db2iupgrade.log, there is DBI20164E The db2iupgrade *
* command failed because of a problem with the DB2 product *
* installation on a host machine in the DB2 cluster. *
* *
* *
* *
* In one of the host: *
* db6c3lp07 (2nd member): /tmp/db2log/DB2Validation.trc: *

* 04:36:09 2014 -- , *
* 12493 |||| 1 db2iHostInfo::WriteInputKey 10 -DATA- , *
* STRING = INSTALLED_DB2_VERSION_REMOTE <-- could this be *
* the problem? But I've installed same version of FP4SB *
* 12494 |||| 1 db2iHostInfo::WriteInputKey 890 -DATA- , *
* STRING = 10.5.0.4 *
* 12495 |||\ 1 db2iHostInfo::WriteInputKey EXIT Fri Sep 26 *

* 12496 ||| 1 IValidatorInstallLocation::isValidRHLoc 50 *
* -DATA- , STRING = Version mismatch *
****************************************************************
* RECOMMENDATION: *
* This problem is fixed in DB210.5 FP5. *
