I have recently had to use the latest ODM drivers since XtremIO isn't supported by my "certified AIX version" of 188.8.131.52. And I noticed that 184.108.40.206 no longer includes high-availability support software for all platforms. Strangely enough, it still includes emcpowerreset utility. Is the high-availability support software now a separate download? Because I don't see /usr/lpp/EMC/Symmetrix/bin/symcurrent or /usr/lpp/EMC/CLARiiON/bin/clarcurrent utilities anymore, but /usr/sbin/cluster/diag/clconraid.dat configuration file is still installed by 220.127.116.11.
Below is an output of software components included with 18.104.22.168 ODM driver, and highlighted in red are what's missing in 22.214.171.124:
126.96.36.199 EMC CELERRA AIX Support Software
188.8.131.52 EMC CELERRA iSCSI Support Software
184.108.40.206 EMC CLARiiON FCP MPIO Support Software
220.127.116.11 EMC CLARiiON HA Concurrent Support
18.104.22.168 EMC CLARiiON iSCSI Support Software
22.214.171.124 EMC INVISTA AIX Support Software
126.96.36.199 EMC INVISTA FCP Support Software
188.8.131.52 EMC Symmetrix AIX Support Software
184.108.40.206 EMC Symmetrix FCP MPIO Support Software
220.127.116.11 EMC Symmetrix FCP Support Software
18.104.22.168 EMC Symmetrix HA Concurrent Support
22.214.171.124 EMC Symmetrix iSCSI Support Software
Can anybody provide clarification on how to ensure the necessary software configured properly for PowerHA for CLARiiON, Symmetrix and XtremIO? Thanks!
If you take a look at the 126.96.36.199/188.8.131.52 readme file in the ODM module, you'll find the following(which was very hard to locate):
OPT 433503 = Removed HA concurrent support package for Symmetrix and CLARiiON considering
those versions of HACMP are no longer supported. Manual deinstallation of the
fileset is required if it's no longer needed.
The HA fileset was needed for HACMP 5.1 and below. It's not needed now.
For XtremIO, I believe you should be using one of the recent ODM versions which has XtremIO support.
(Again, you will probably have to check the readme files in the ODM one by one for any differences)
The HA Concurrent Support filesets were removed in the 184.108.40.206 version of the ODM definitions as they were no longer required.
The functionality provided by the HA Concurrent support filesets was only required up to and including HACMP 5.1, which went end of support with IBM in 2006.
With the functionality no longer required for the versions of PowerHA that IBM currently support (6.1/7.1), the decision was taken to remove these filesets from the ODM definitions.
The README file associated with the 220.127.116.11 ODM Definitions refer to this:
OPT 433503 = Removed HA concurrent support package for Symmetrix and CLARiiON considering those versions of HACMP are no longer supported.
Therefore regardless of whether the Symm/Clariion/XtremIO devices are being used in a PowerHA 6.1/7.1 clustered environment or not, there is no requirement to install the EMC HA Concurrent Support Filesets that were previously available in pre-18.104.22.168 versions of the ODM definitions.
Thanks Owen & Ray. This is interesting, because back during the days of HACMP 5.4.1 (a major mid cycle release), I still had to use the HA concurrent support filesets. If HA concurrent support filesets are no longer needed, why would EMC still package /usr/sbin/cluster/diag/clconraid.dat in ODM 22.214.171.124? The two utilities I mentioned that comes from the HA concurrent support filesets are used to set up this clconraid.dat file. Oh well, I went ahead and manually configured the clconraid.dat file and see if that works.
