 So this is either a semantic error and the goal was actually to check for the symlinks to be created already being present, in which case e.g. ''/usr/hmcrbin/lsnodeid'' should be in the test brakets. Or this is not a semantic error, in which case the aforementioned test for the symlinks to be created already being present should actually be implemented or the symlink creation should be forced ("''-f''" flag). Besides that i would've probably handled the symlink creation in the RPM that installs the binaries in the first place. Well lets open a PMR on this and find out what IBM thinks about this issue. So this is either a semantic error and the goal was actually to check for the symlinks to be created already being present, in which case e.g. ''/usr/hmcrbin/lsnodeid'' should be in the test brakets.

 +Another issue - although a minor one - with the above code expamle is in lines 532 and 534. The shells [[http://www.tldp.org/LDP/abs/html/io-redirection.html|I/O redirection]] is used in the wrong order, causing STDOUT to be redirected to STDERR instead of - what was probably intended - both being redirected to ''/dev/null''.
  
 Aside from that we're currently not experiencing any issues with the new HMC version. I've opened up a RPQ to get the feature [[http://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_rp/6/ENUSP91276/index.html&lang=unknown|5799 - HMC remote restart function]], which is again supported with v7.7.6.0 SP1 ([[http://www-933.ibm.com/support/fixcentral/firmware/readme?fixid=MH01329|MH01329]]). This will come in quite handy for the simplification of our disaster recovery procedures. But that'll be material for another post. Stay tuned until then ... Aside from that we're currently not experiencing any issues with the new HMC version.
